This system creates a low-cost IoT-based monitoring system for power grid transformers to monitor their status in real-time. Sensors measure temperature, humidity, oil level, voltage, vibration, and pressure and send the data via ESP32 to a cloud interface. This allows maintenance centers to detect abnormalities before failures and improve transformer efficiency in smart grids. The low-cost system was built for under $23 using inexpensive and accessible components like an ESP32 board, DHT22 sensor, and ultrasonic sensor. It demonstrates the feasibility of remotely monitoring transformers to extend their lifetimes.

In this paper, a prototype DC electric system was practically designed. The idea of the proposed system was derived from the microgrid concept. The system contained two houses each have a DC generator and load that consists of four 12 V DC lamps. Each house is controlled fully by Arduino UNO microcontroller to work in Island mode or connected it with the second house or main electric network. House operating mode depends on the power generated by its source and the availability of the main network. Under all operating cases, the minimum price of electricity consumption should satisfy as possible. Information between the houses about the operating mode and the main network state was exchanging wirelessly with the help of the RFHC12. This information uploaded to the Ubidots platform by the Wi-FiESP8266 included in the node MCU microcontroller. This platform has several advantages such as capture, visualization, analysis, and management of data. The system was examined for different cases to verify its working by varying the load in each building. All tested states showed that the houses transfer from one mode to another automatically with high reliability and minimum energy cost.

Integration of internet of things with wireless sensor networkIJECEIAES
The Internet of things (IoT) is a major source for technology solutions in many industries. The IoT can consider, Wireless Sensor Network (WSN) as the backbone network to reduce formation or advent of new technology. Integration of these would reduce the burden and form smart sensor node network with nodes given access to internet. WSN is already a major legacy system that has percolated into many industries. Thus by integration of IoT and WSN no huge paradigm shift is needed for the industries.
Building the smart grid means integration of advanced information, communication and networking
technologies in the traditional electric grid to make it smarter and faster in making decisions. IoT platform
provides very high redundancy, virtually unlimited data storage and worldwide data access. Through the IoT,
consumers, manufacturers and utility providers will uncover new ways to manage devices and ultimately conserve

The use of the internet of things (IoT) in solar photovoltaic (PV) systems is a critical feature for remote monitoring, supervising, and performance evaluation. Furthermore, it improves the long-term viability, consistency, efficiency, and system maintenance of energy production. However, previous researchers' proposed PV monitoring systems are relatively complex and expensive. Furthermore, the existing systems do not have any backup data, which means that the acquired data could be lost if the network connection fails. This paper presents a simple and low-cost IoT-based PV parameter monitoring system, with additional backup data stored on a microSD card. A NodeMCU ESP8266 development board is chosen as the main controller because it is a system-on-chip (SOC) microcontroller with integrated Wi-Fi and low-power support, all in one chip to reduce the cost of the proposed system. The solar irradiance, ambient temperature, PV output voltage and PV output current, are measured with photo-diodes, DHT22, impedance dividers and ACS712. While, the PV output power is a product of the PV voltage and PV current. ThingSpeak, an opensource software, is used as a cloud database and data monitoring tool in the form of interactive graphics. The results showed that the system was designed to be highly accurate, reliable, simple to use, and low-cost.

The Ubiquitous Power Internet of Things (UPIoT) is a deep integration of the interconnected power
network and communication network, enabling full perception of the system status and business operations
for power production, transmission, and consumption. To address the challenges of real-time perception,
rapid response, and privacy protection, UPIoT can benefit from the use of edge computing technology.
Edge computing is a new and innovative computing architecture that enables quick and efficient
processing of data close to the source, bypassing network latency and bandwidth issues. By shifting
computing power to the edge of the network, edge computing reduces the strain on cloud computing
centers and decreases input response time for users. However, access latency can still be a bottleneck,
which may overshadow the benefits of edge computing, particularly for data-intensive services. While edge
computing offers promising solutions for the IoT network, there are still some issues to address, such as
security, incomplete data, and investment and maintenance costs. In this paper, researcher conducts a
comprehensive survey of edge computing and how edge device placement can improve performance in IoT
networks. The paper includes a comparative use case of smart agriculture edge computing
implementations and discusses the various challenges faced in implementing edge computing in the UPIoT

Fossil fuel consumption increased quickly, contributing to climate change

particularly SDG 7 and SDG 13. The results considered contributions made
by women in the various sectors while taking geographic dispersion into
account. The bibliometric analysis delves into topics including women's
leadership in environmental groups, their involvement in policymaking, their
contributions to sustainable development projects, and the influence of
gender diversity on attempts to mitigate climate change. This study's results
highlight how women have influenced policies and actions related to climate

The active and reactive load changes have a significant impact on voltage
and frequency. In this paper, in order to stabilize the microgrid (MG) against
load variations in islanding mode, the active and reactive power of all
distributed generators (DGs), including energy storage (battery), diesel
generator, and micro-turbine, are controlled. The micro-turbine generator is
connected to MG through a three-phase to three-phase matrix converter, and
the droop control method is applied for controlling the voltage and
frequency of MG. In addition, a method is introduced for voltage and
frequency control of micro-turbines in the transition state from gridconnected mode to islanding mode. A novel switching strategy of the matrix
converter is used for converting the high-frequency output voltage of the
micro-turbine to the grid-side frequency of the utility system. Moreover,
using the switching strategy, the low-order harmonics in the output current
and voltage are not produced, and consequently, the size of the output filter
would be reduced. In fact, the suggested control strategy is load-independent
and has no frequency conversion restrictions. The proposed approach for
voltage and frequency regulation demonstrates exceptional performance and
favorable response across various load alteration scenarios. The suggested
strategy is examined in several scenarios in the MG test systems, and the
simulation results are addressed.

article introduces an innovative nonlinear methodology for system
identification of a Li-ion battery, employing a nonlinear autoregressive with
exogenous inputs (NARX) model. The proposed approach integrates the
benefits of nonlinear modeling with the adaptability of the NARX structure,
facilitating a more comprehensive representation of the intricate
electrochemical processes within the battery. Experimental data collected
from a Li-ion battery operating under diverse scenarios are employed to
validate the effectiveness of the proposed methodology. The identified
NARX model exhibits superior accuracy in predicting the battery's behavior
compared to traditional linear models. This study underscores the
importance of accounting for nonlinearities in battery modeling, providing
insights into the intricate relationships between state-of-charge, voltage, and
current under dynamic conditions.
Smart grid deployment: from a bibliometric analysis to a surveyIJECEIAES
Smart grids are one of the last decades' innovations in electrical energy.
They bring relevant advantages compared to the traditional grid and
significant interest from the research community. Assessing the field's
evolution is essential to propose guidelines for facing new and future smart
grid challenges. In addition, knowing the main technologies involved in the
deployment of smart grids (SGs) is important to highlight possible
shortcomings that can be mitigated by developing new tools. This paper
contributes to the research trends mentioned above by focusing on two
objectives. First, a bibliometric analysis is presented to give an overview of
the current research level about smart grid deployment. Second, a survey of
the main technological approaches used for smart grid implementation and
their contributions are highlighted. To that effect, we searched the Web of
Science (WoS), and the Scopus databases. We obtained 5,663 documents
from WoS and 7,215 from Scopus on smart grid implementation or
deployment. With the extraction limitation in the Scopus database, 5,872 of
the 7,215 documents were extracted using a multi-step process. These two
datasets have been analyzed using a bibliometric tool called bibliometrix.
The main outputs are presented with some recommendations for future
research.

One of the problems that are associated to power systems is islanding
condition, which must be rapidly and properly detected to prevent any
negative consequences on the system's protection, stability, and security.
This paper offers a thorough overview of several islanding detection
strategies, which are divided into two categories: classic approaches,
including local and remote approaches, and modern techniques, including
techniques based on signal processing and computational intelligence.
Additionally, each approach is compared and assessed based on several
factors, including implementation costs, non-detected zones, declining
power quality, and response times using the analytical hierarchy process
(AHP). The multi-criteria decision-making analysis shows that the overall
weight of passive methods (24.7%), active methods (7.8%), hybrid methods
(5.6%), remote methods (14.5%), signal processing-based methods (26.6%),
and computational intelligent-based methods (20.8%) based on the
comparison of all criteria together. Thus, it can be seen from the total weight
that hybrid approaches are the least suitable to be chosen, while signal
processing-based methods are the most appropriate islanding detection
method to be selected and implemented in power system with respect to the
aforementioned factors. Using Expert Choice software, the proposed
hierarchy model is studied and examined.

The power generated by photovoltaic (PV) systems is influenced by
environmental factors. This variability hampers the control and utilization of
solar cells' peak output. In this study, a single-stage grid-connected PV
system is designed to enhance power quality. Our approach employs fuzzy
logic in the direct power control (DPC) of a three-phase voltage source
inverter (VSI), enabling seamless integration of the PV connected to the
grid. Additionally, a fuzzy logic-based maximum power point tracking
(MPPT) controller is adopted, which outperforms traditional methods like
incremental conductance (INC) in enhancing solar cell efficiency and
minimizing the response time. Moreover, the inverter's real-time active and
reactive power is directly managed to achieve a unity power factor (UPF).
The system's performance is assessed through MATLAB/Simulink
implementation, showing marked improvement over conventional methods,
particularly in steady-state and varying weather conditions. For solar
irradiances of 500 and 1,000 W/m2
, the results show that the proposed
method reduces the total harmonic distortion (THD) of the injected current
to the grid by approximately 46% and 38% compared to conventional
methods, respectively. Furthermore, we compare the simulation results with
IEEE standards to evaluate the system's grid compatibility.

Photovoltaic systems have emerged as a promising energy resource that
caters to the future needs of society, owing to their renewable, inexhaustible,
and cost-free nature. The power output of these systems relies on solar cell
radiation and temperature. In order to mitigate the dependence on
atmospheric conditions and enhance power tracking, a conventional
approach has been improved by integrating various methods. To optimize
the generation of electricity from solar systems, the maximum power point
tracking (MPPT) technique is employed. To overcome limitations such as
steady-state voltage oscillations and improve transient response, two
traditional MPPT methods, namely fuzzy logic controller (FLC) and perturb
and observe (P&O), have been modified. This research paper aims to
simulate and validate the step size of the proposed modified P&O and FLC
techniques within the MPPT algorithm using MATLAB/Simulink for
efficient power tracking in photovoltaic systems.
Adaptive synchronous sliding control for a robot manipulator based on neural ...IJECEIAES
Robot manipulators have become important equipment in production lines, medical fields, and transportation. Improving the quality of trajectory tracking for
robot hands is always an attractive topic in the research community. This is a
challenging problem because robot manipulators are complex nonlinear systems
and are often subject to fluctuations in loads and external disturbances. This
article proposes an adaptive synchronous sliding control scheme to improve trajectory tracking performance for a robot manipulator. The proposed controller
ensures that the positions of the joints track the desired trajectory, synchronize
the errors, and significantly reduces chattering. First, the synchronous tracking
errors and synchronous sliding surfaces are presented. Second, the synchronous
tracking error dynamics are determined. Third, a robust adaptive control law is
designed,the unknown components of the model are estimated online by the neural network, and the parameters of the switching elements are selected by fuzzy
logic. The built algorithm ensures that the tracking and approximation errors
are ultimately uniformly bounded (UUB). Finally, the effectiveness of the constructed algorithm is demonstrated through simulation and experimental results.
Simulation and experimental results show that the proposed controller is effective with small synchronous tracking errors, and the chattering phenomenon is
significantly reduced.

A remote laboratory utilizing field-programmable gate array (FPGA) technologies enhances students’ learning experience anywhere and anytime in embedded system design. Existing remote laboratories prioritize hardware access and visual feedback for observing board behavior after programming, neglecting comprehensive debugging tools to resolve errors that require internal signal acquisition. This paper proposes a novel remote embeddedsystem design approach targeting FPGA technologies that are fully interactive via a web-based platform. Our solution provides FPGA board access and debugging capabilities beyond the visual feedback provided by existing remote laboratories. We implemented a lab module that allows users to seamlessly incorporate into their FPGA design. The module minimizes hardware resource utilization while enabling the acquisition of a large number of data samples from the signal during the experiments by adaptively compressing the signal prior to data transmission. The results demonstrate an average compression ratio of 2.90 across three benchmark signals, indicating efficient signal acquisition and effective debugging and analysis. This method allows users to acquire more data samples than conventional methods. The proposed lab allows students to remotely test and debug their designs, bridging the gap between theory and practice in embedded system design.
Detecting and resolving feature envy through automated machine learning and m...IJECEIAES
Efficiently identifying and resolving code smells enhances software project quality. This paper presents a novel solution, utilizing automated machine learning (AutoML) techniques, to detect code smells and apply move method refactoring. By evaluating code metrics before and after refactoring, we assessed its impact on coupling, complexity, and cohesion. Key contributions of this research include a unique dataset for code smell classification and the development of models using AutoGluon for optimal performance. Furthermore, the study identifies the top 20 influential features in classifying feature envy, a well-known code smell, stemming from excessive reliance on external classes. We also explored how move method refactoring addresses feature envy, revealing reduced coupling and complexity, and improved cohesion, ultimately enhancing code quality. In summary, this research offers an empirical, data-driven approach, integrating AutoML and move method refactoring to optimize software project quality. Insights gained shed light on the benefits of refactoring on code quality and the significance of specific features in detecting feature envy. Future research can expand to explore additional refactoring techniques and a broader range of code metrics, advancing software engineering practices and standards.

Rapidly and remotely monitoring and receiving the solar cell systems status parameters, solar irradiance, temperature, and humidity, are critical issues in enhancement their efficiency. Hence, in the present article an improved smart prototype of internet of things (IoT) technique based on embedded system through NodeMCU ESP8266 (ESP-12E) was carried out experimentally. Three different regions at Egypt; Luxor, Cairo, and El-Beheira cities were chosen to study their solar irradiance profile, temperature, and humidity by the proposed IoT system. The monitoring data of solar irradiance, temperature, and humidity were live visualized directly by Ubidots through hypertext transfer protocol (HTTP) protocol. The measured solar power radiation in Luxor, Cairo, and El-Beheira ranged between 216-1000, 245-958, and 187-692 W/m 2 respectively during the solar day. The accuracy and rapidity of obtaining monitoring results using the proposed IoT system made it a strong candidate for application in monitoring solar cell systems. On the other hand, the obtained solar power radiation results of the three considered regions strongly candidate Luxor and Cairo as suitable places to build up a solar cells system station rather than El-Beheira.
An efficient security framework for intrusion detection and prevention in int...IJECEIAES
Over the past few years, the internet of things (IoT) has advanced to connect billions of smart devices to improve quality of life. However, anomalies or malicious intrusions pose several security loopholes, leading to performance degradation and threat to data security in IoT operations. Thereby, IoT security systems must keep an eye on and restrict unwanted events from occurring in the IoT network. Recently, various technical solutions based on machine learning (ML) models have been derived towards identifying and restricting unwanted events in IoT. However, most ML-based approaches are prone to miss-classification due to inappropriate feature selection. Additionally, most ML approaches applied to intrusion detection and prevention consider supervised learning, which requires a large amount of labeled data to be trained. Consequently, such complex datasets are impossible to source in a large network like IoT. To address this problem, this proposed study introduces an efficient learning mechanism to strengthen the IoT security aspects. The proposed algorithm incorporates supervised and unsupervised approaches to improve the learning models for intrusion detection and mitigation. Compared with the related works, the experimental outcome shows that the model performs well in a benchmark dataset. It accomplishes an improved detection accuracy of approximately 99.21%.

This research is developing an incubator system that integrates the internet of things and artificial intelligence to improve care for premature babies. The system workflow starts with sensors that collect data from the incubator. Then, the data is sent in real-time to the internet of things (IoT) broker eclipse mosquito using the message queue telemetry transport (MQTT) protocol version 5.0. After that, the data is stored in a database for analysis using the long short-term memory network (LSTM) method and displayed in a web application using an application programming interface (API) service. Furthermore, the experimental results produce as many as 2,880 rows of data stored in the database. The correlation coefficient between the target attribute and other attributes ranges from 0.23 to 0.48. Next, several experiments were conducted to evaluate the model-predicted value on the test data. The best results are obtained using a two-layer LSTM configuration model, each with 60 neurons and a lookback setting 6. This model produces an R 2 value of 0.934, with a root mean square error (RMSE) value of 0.015 and a mean absolute error (MAE) of 0.008. In addition, the R 2 value was also evaluated for each attribute used as input, with a result of values between 0.590 and 0.845.

Honey is produced exclusively by honeybees and stingless bees which both are well adapted to tropical and subtropical regions such as Malaysia. Stingless bees are known for producing small amounts of honey and are known for having a unique flavor profile. Problem identified that many stingless bees collapsed due to weather, temperature and environment. It is critical to understand the relationship between the production of stingless bee honey and environmental conditions to improve honey production. Thus, this paper presents a review on stingless bee's honey production and prediction modeling. About 54 previous research has been analyzed and compared in identifying the research gaps. A framework on modeling the prediction of stingless bee honey is derived.

A trust based secure access control using authentication mechanism for intero...IJECEIAES
The internet of things (IoT) is a revolutionary innovation in many aspects of our society including interactions, financial activity, and global security such as the military and battlefield internet. Due to the limited energy and processing capacity of network devices, security, energy consumption, compatibility, and device heterogeneity are the long-term IoT problems. As a result, energy and security are critical for data transmission across edge and IoT networks. Existing IoT interoperability techniques need more computation time, have unreliable authentication mechanisms that break easily, lose data easily, and have low confidentiality. In this paper, a key agreement protocol-based authentication mechanism for IoT devices is offered as a solution to this issue. This system makes use of information exchange, which must be secured to prevent access by unauthorized users. Using a compact contiki/cooja simulator, the performance and design of the suggested framework are validated. The simulation findings are evaluated based on detection of malicious nodes after 60 minutes of simulation. The suggested trust method, which is based on privacy access control, reduced packet loss ratio to 0.32%, consumed 0.39% power, and had the greatest average residual energy of 0.99 mJoules at 10 nodes.
Fuzzy linear programming with the intuitionistic polygonal fuzzy numbersIJECEIAES
In real world applications, data are subject to ambiguity due to several factors; fuzzy sets and fuzzy numbers propose a great tool to model such ambiguity. In case of hesitation, the complement of a membership value in fuzzy numbers can be different from the non-membership value, in which case we can model using intuitionistic fuzzy numbers as they provide flexibility by defining both a membership and a non-membership functions. In this article, we consider the intuitionistic fuzzy linear programming problem with intuitionistic polygonal fuzzy numbers, which is a generalization of the previous polygonal fuzzy numbers found in the literature. We present a modification of the simplex method that can be used to solve any general intuitionistic fuzzy linear programming problem after approximating the problem by an intuitionistic polygonal fuzzy number with n edges. This method is given in a simple tableau formulation, and then applied on numerical examples for clarity.
The performance of artificial intelligence in prostate magnetic resonance im...IJECEIAES
Prostate cancer is the predominant form of cancer observed in men worldwide. The application of magnetic resonance imaging (MRI) as a guidance tool for conducting biopsies has been established as a reliable and well-established approach in the diagnosis of prostate cancer. The diagnostic performance of MRI-guided prostate cancer diagnosis exhibits significant heterogeneity due to the intricate and multi-step nature of the diagnostic pathway. The development of artificial intelligence (AI) models, specifically through the utilization of machine learning techniques such as deep learning, is assuming an increasingly significant role in the field of radiology. In the realm of prostate MRI, a considerable body of literature has been dedicated to the development of various AI algorithms. These algorithms have been specifically designed for tasks such as prostate segmentation, lesion identification, and classification. The overarching objective of these endeavors is to enhance diagnostic performance and foster greater agreement among different observers within MRI scans for the prostate. This review article aims to provide a concise overview of the application of AI in the field of radiology, with a specific focus on its utilization in prostate MRI.
Seizure stage detection of epileptic seizure using convolutional neural networksIJECEIAES
According to the World Health Organization (WHO), seventy million individuals worldwide suffer from epilepsy, a neurological disorder. While electroencephalography (EEG) is crucial for diagnosing epilepsy and monitoring the brain activity of epilepsy patients, it requires a specialist to examine all EEG recordings to find epileptic behavior. This procedure needs an experienced doctor, and a precise epilepsy diagnosis is crucial for appropriate treatment. To identify epileptic seizures, this study employed a convolutional neural network (CNN) based on raw scalp EEG signals to discriminate between preictal, ictal, postictal, and interictal segments. The possibility of these characteristics is explored by examining how well timedomain signals work in the detection of epileptic signals using intracranial Freiburg Hospital (FH), scalp Children's Hospital Boston-Massachusetts Institute of Technology (CHB-MIT) databases, and Temple University Hospital (TUH) EEG. To test the viability of this approach, two types of experiments were carried out. Firstly, binary class classification (preictal, ictal, postictal each versus interictal) and four-class classification (interictal versus preictal versus ictal versus postictal). The average accuracy for stage detection using CHB-MIT database was 84.4%, while the Freiburg database's time-domain signals had an accuracy of 79.7% and the highest accuracy of 94.02% for classification in the TUH EEG database when comparing interictal stage to preictal stage.
Analysis of driving style using self-organizing maps to analyze driver behaviorIJECEIAES
Modern life is strongly associated with the use of cars, but the increase in acceleration speeds and their maneuverability leads to a dangerous driving style for some drivers. In these conditions, the development of a method that allows you to track the behavior of the driver is relevant. The article provides an overview of existing methods and models for assessing the functioning of motor vehicles and driver behavior. Based on this, a combined algorithm for recognizing driving style is proposed. To do this, a set of input data was formed, including 20 descriptive features: About the environment, the driver's behavior and the characteristics of the functioning of the car, collected using OBD II. The generated data set is sent to the Kohonen network, where clustering is performed according to driving style and degree of danger. Getting the driving characteristics into a particular cluster allows you to switch to the private indicators of an individual driver and considering individual driving characteristics. The application of the method allows you to identify potentially dangerous driving styles that can prevent accidents.
Hyperspectral object classification using hybrid spectral-spatial fusion and ...IJECEIAES
Because of its spectral-spatial and temporal resolution of greater areas, hyperspectral imaging (HSI) has found widespread application in the field of object classification. The HSI is typically used to accurately determine an object's physical characteristics as well as to locate related objects with appropriate spectral fingerprints. As a result, the HSI has been extensively applied to object identification in several fields, including surveillance, agricultural monitoring, environmental research, and precision agriculture. However, because of their enormous size, objects require a lot of time to classify; for this reason, both spectral and spatial feature fusion have been completed. The existing classification strategy leads to increased misclassification, and the feature fusion method is unable to preserve semantic object inherent features; This study addresses the research difficulties by introducing a hybrid spectral-spatial fusion (HSSF) technique to minimize feature size while maintaining object intrinsic qualities; Lastly, a soft-margins kernel is proposed for multi-layer deep support vector machine (MLDSVM) to reduce misclassification. The standard Indian pines dataset is used for the experiment, and the outcome demonstrates that the HSSF-MLDSVM model performs substantially better in terms of accuracy and Kappa coefficient.
Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

One of the most common causes of blackouts is unexpected failures at
power system transformer levels. The purpose of this project is to create a
low-cost Internet of things (IoT)-based monitoring system for power grid
transformers in order to investigate their working status in real-time. Our
monitoring system’s key functions are the gathering and display of many
metrics measured at the transformer level (temperature, humidity, oil level,
voltage, vibration, and pressure). The data will be collected using various
sensors connected to a microcontroller with an embedded Wi-Fi module
(DOIT Esp32 DevKit v1), and then supplied to a cloud environment
interface with a full display of all the ongoing changes. This technology will
provide the power grid maintenance center with a clear image of the
transformers’ health, allowing them to intervene at the right time to prevent
system breakdown. The method described above would considerably
improve the efficiency of a power transformer in a smart grid system by
detecting abnormalities before they become critical.

1. INTRODUCTION
The internet of things (IoT) is a fast-increasing technology that links everything and enables
effective communication between the linked “things”. The IoT, also known as the internet of objects, refers
to a remote system connecting objects; often, the system will be remote and self-designing, such as family
unit machines [1]. The phrase “Internet of Things” has evolved to refer to several technologies and study
fields that allow the internet to extend out into the physical world of tangible items. Traffic monitoring,
healthcare, security, transportation and logistics, and daily living are the top five IoT applications. In this
paper, we are going to take advantage of these IoT technologies to improve one of the functional prospects of
a power grid.
A traditional power grid consists of a large number of loosely connected synchronous alternating
current (AC) networks. It fulfills three main functions: generation, transmission, and distribution of electrical
energy. Each network is centrally controlled and monitored in order to ensure that the power plants generate
electrical energy as required within the framework of the electricity network [2]. Power grids also face a

number of other challenges, including growing energy demands, reliability, security, new renewable energy
sources, and aging infrastructure problems. To solve these challenges, the smart grid (SG) paradigm has
proven to be a promising solution with a variety of information and communication technologies [3]. In
power transmission, the electricity from power plants to remote load centers is carried over high-voltage
transmission lines. SG uses different types of devices to monitor, analyze, and control the network, so it
becomes useful for many tasks, like making important decisions based on energy needs. The monitoring
devices are used in power plants, overhead lines, transmission towers, and distribution centers [2]. Whereas a
power grid comprises numerous transformers that are needed for the transmission and distribution of
electrical energy, one of the current vital goals is to assure the proper operation of these critical components
while also extending their life [4]. This is now a feasible aim owing to IoT-based monitoring devices that can
easily be implemented to monitor the functioning state of transformers at various levels of the grid [5].
Governments all around the world are focused on adopting and integrating smart grid technologies
as the old grid infrastructure ages and struggles to keep up with rising power consumption. For years, the
European Union has focused on it as a system to “efficiently offer ecological, economic, and secure power
supplies”. Many studies have been conducted in preparation for this trip [6].
Shastrimath et al. [7] developed a fault detection and protection system for power transformers
based on Arduino. Instead of differential relays, Arduino was used to monitor transformer functioning and
create tripping or alarm signals based on observed values. Fault signals were sent to a Wi-Fi module and
displayed on the Blynk app. The control system was implemented using an Arduino ATmega328
microcontroller with a 16 MHz crystal. The temperature of the transformer was measured using an LM-35
temperature sensor. The voltage, current, and temperature readings were presented on the liquid-crystal
display (LCD). In [8], a program that enables power levels and control devices to be obtained from any
location on the planet was proposed. A sensor was put on the heap to identify the current, and a circuit was
utilized to measure the voltage; power estimation was performed using these two, and control characteristics
were discarded in a cloud database. The major aims of the study [9] were to monitor the electrical grid
system process, reveal this system at a harmful level, monitor the current line, and minimize conventional
system expenditures. In this work, an electrical microcontroller was set up to monitor a single-phase
electrical device using an Arduino to read sensor voltage and current and then transfer measured data via a
new Android application for wireless monitoring.
Pursuing the research work [7]–[9] that has been done in the same context, we designed a more
precise and improved monitoring system that can collect the maximum information about a transformer’s
working conditions in real-time and provide visualization as well as the possibility of future analysis using
the gathered data at a lower cost by using a simple design that can be easily implemented. This system will
allow us to detect and correct the problem as soon as it occurs. This can definitely help us extend the
transformer’s life-time.
2. INTERNET OF THINGS SYSTEMS AND REAL-TIME DATA COLLECTION
There has been a tremendous growth in the number of smart devices and their applications (e.g.,
smart sensors, wearable devices, smart phones, and smart cars). This is accompanied by a new form of
interconnection between the physical and digital worlds, commonly known as the IoT [10]. Therefore, the
core idea behind the Internet of Things is to connect numerous objects utilizing technologies such as radio
frequency identification (RFID), sensors, actuators, and smartphones, allowing these products to
communicate with one another. IoT relies on smart devices with a range of capabilities, such as sensing,
networking, processing, and actuation, as a dynamic global network architecture, allowing people and things
to interact in various and complicated environments [11].
Real-time data refers to information that is supplied as soon as it is collected. Real-time data is
frequently employed in navigation and tracking and can be either static or dynamic, like in our system that
collects diverse values at a specific time and then continuously repeats the same operation after a defined
delay [12]. However, it is vital to highlight that real-time data does not imply that the data is immediately
available to the end user. There might be any variety of bottlenecks in the data gathering infrastructure,
bandwidth between multiple parties, or even the end user’s personal computer (PC). Real-time data does not
guarantee data in a specific number of microseconds, but it is still extremely essential in applications such as
traffic global positioning system (GPS) systems, which display to drivers what is going on around them [13].
It is useful for all types of analytics initiatives as well as keeping people informed about their natural
surroundings due to its capacity for fast data distribution. The model in the early days of computers was to
capture any data for storage. With the growth of mobile devices and other technological breakthroughs, it is
becoming increasingly common for software to simply transmit acquired data straight to an end user [14].
This data may be then used to improve products, services, and experiences. To get the most out of their

investments, companies must ensure that they have the infrastructure in place to handle real-time data
processing at scale [15].
3. FAULTS IN POWER GRID TRANSFORMERS
A defect might have an impact on transformer performance. Faults can appear in any transformer,
new or old, and can lead to expensive transformer failures. All the problems that can occur at the transformer
level can be classified as one of the two main fault types, which are external faults or internal faults. External
faults are faults outside a transformer while internal faults are faults inside a transformer. Those two
categories can be divided into sub-categories in this section [16]–[18].
3.1. External faults in a power transformer
3.1.1. External short circuit of a power transformer
A short circuit can happen in two or three phases of an electrical power supply. It is determined by
the voltage that has been short-circuited as well as the impedance of the circuit up to the fault location. A
high fault current causes substantial mechanical strains in the transformer.
3.1.2. Under frequency effect in a power transformer
The phenomena of a reduction in the transformer’s impedance with a drop in the applied frequency
is referred to as the under-frequency effect in power transformers. When the frequency of a system is
reduced, the flow in the core increases, and the impact is comparable to that of an overvoltage. The impact is
strongest at low frequencies. Under frequency protection is used to lessen the impacts of this phenomena by
detecting a fall in system frequency and immediately commencing a load shedding scheme to reduce system
load.
3.1.3. High voltage disturbance in a power transformer
High voltage and high frequency surges in the power system can occur as a result of any of the
following: arcing ground if the neutral point is isolated; changing the operation of various electrical devices;
and lightning strikes in the atmosphere. All of these can cause breakdowns in the insulation between turns
adjacent to line terminals, which may create short circuits. There is always the possibility of system
overvoltage due to the unexpected separation of a big load. Overvoltage in the system increases the stress on
the transformer insulation. Core bolts, which ordinarily transport minimal flow, may be exposed to a
significant component of flow redirected from the saturated section of the core beneath. Under such
conditions, the bolt may get quickly heated, destroying both its own and the winding insulation.
3.2. Internal short circuit of a power transformer
3.2.1. Inter turns fault in a power transformer
Due to a lightning surge on the transmission line, a power transformer linked to an electrical extra
high voltage transmission system is highly likely to be subjected to large magnitude, steep slope, and high
frequency impulse voltage. The voltage strains between winding turns grow so great that they cannot be
sustained, resulting in insulation breakdown in some places. The transmitted surge voltage stresses the low
voltage (LV) winding.
3.2.2. Internal earth faults in a star connected winding with neutral point solidly earthed
The value of fault current in a star-connected winding with a securely earthed neutral point is
determined by two major elements. Fault current is proportional to the leakage reactance of the part of the
winding that connects the defective and neutral points of the transformer. It can be observed that the
reactance reduces extremely quickly as the fault point approaches the neutral, and hence the fault current is
greatest towards the neutral end. In this scenario, the earthing impedance should be zero.
3.2.3. Internal earth faults in a star connected winding with neutral point earthed through an impedance
The value of fault current is determined by the earthing impedance as well as the distance between
the defective and neutral points. The voltage at the fault site in this situation is determined by the number of
windings turns that occur across neutral and the fault point. The fault current is also affected by the leakage
reactance of the section of the winding that is connected to the faults and neutral. However, in comparison to
the earthing impedance, it is relatively low, and it is plainly neglected since it is in series with considerably
greater earthing impedances.

4. BUILDING THE MONITORING SYSTEM
Gathering the data from the transformer environment requires having different sensing units that
will allow us to trigger the surrounding conditions of these power grid components. All the collected data
will be processed by the programmable microcontroller that will send it via Wi-Fi to a cloud environment
where it will be displayed and visualized. Therefore, our system can be divided into three main levels, as
shown in Figure 1.
Figure 1. Levels of our monitoring system
4.1. Used tools and their estimated cost
The primary goal of this paper is to not only build a monitoring system for power grid transformers,
but also to make this system simple and functional at a lower cost. For this reason, the chosen materials are as
shown in Table 1. These materials are inexpensive and widely available. They are also easy to work with and
do not require complex implementation steps.
4.1.1. Hardware
Table 1 shows the hardware components used to build the system and how much each one costs,
while Figure 2 shows how the components are linked together to form the system. The main component
which is the ESP32 card costs only 10 dollars. The system as a whole cost less than 23 dollars in total.
Table 1. Estimated cost for used equipment

DHT22 Temperature and Humidity sensor 6$
2 Resistances 1.5$
Ultrasonic distance sensor-HC-SR04 3$
SW-420 vibration sensor 2.5$
Total cost 23$
4.1.2. Software
ThingSpeak, an open-source program for internet-enabled device connections, was chosen as our
cloud environment for free data presentation [19]. We made a private channel on ThingSpeak and then
decided how many fields we wanted on it. As seen in Figure 3, we also labeled each field after the parameter

5. METHODOLOGY DEVELOPMENT
5.1. Building the test system
Transformers are typically housed in oil tanks, big drums, or pipelines. If a transformer is put in a
tank, the tank must be completely sealed to avoid oil spillage in the event of a leak. The tank is often filled
with a cooling substance, such as oil. The cooling agent is used to disperse the heat generated by the
transformer when it is in operation. Therefore, to test the system, we used a small transformer (input voltage:
220 V and output voltage: 12/24 V) and an alimentation bloc that can create 220 V. We put the transformer
in a 20-centimeter-high container filled with mineral oil (oil density=0.84 g/cm3
) to simulate the environment
of a genuine power grid transformer, as illustrated in Figure 4.

5.2. Data collection
5.2.1. Temperature and humidity sensing
We used a DHT22, which can measure both values with very acceptable precision (temperature
accuracy of 2%-5% and humidity accuracy of 5%). The temperature range of the DHT22 is 40 to 80 °C [20],
whereas the maximum temperature of a normal transformer is supposed to be 40°C [21]. This means the
measurement range provided by DHT22 is enough for our system.
5.2.2. Voltage and current sensing
We just need to build a voltage divider between our board’s VCC and ground pins to monitor
voltage and then compute current because the ESP32 can already receive analog input between 0 and 3.3 V.
The resistance values R1 and R2 must be carefully set to offer a sufficient measuring range. The resistances
of R1=100 kOhms and R2=1 kOhm were chosen to enable a maximum measurement of 300 V. The
measurement range supplied is adequate because the maximum voltage across the transformer secondary
under consideration will not exceed 24 V (the maximum output voltage of the transformer we used to verify
system performance). Figure 5 depicts the voltage divider we used to gather voltage measurements around
the transformer secondary. If this last has a different voltage range, it is easy to substitute resistances in the
system with others that have acceptable values while respecting the 0 3.3 V in (1) [22].
𝑉𝑜𝑢𝑡 = 𝑉𝑠𝑒𝑐𝑜𝑛𝑑𝑎𝑟𝑦 ∗ 𝑅2/(𝑅1 + 𝑅2) (1)
The reason behind excluding current visualization is that its value depends directly on the voltage value,
which means that observing voltage changes is enough to know how the current at the level of the
transformer secondary is changing as well. Here is the equation that represents current values based on
voltage value (Ohm’s law).
𝐼 = 𝑉𝑜𝑢𝑡/𝑅2 (2)
Figure 5. Voltage divider implementation
5.2.3. Oil level and pressure sensing
We measured the distance between the upper portion of the transformer container and the upper
portion of the oil using an ultrasonic distance sensor-HC-SR04 as shown in Figure 4, which allowed us to
compute the oil level using (3):
𝑂 = 𝐻 − 𝐷 (3)
where O is oil level, H is transformer container’s height, and D is distance between the upper part of the
transformer container and the higher level of the oil. For the pressure it is calculated using (4) [23]:
𝑃 = 𝑂. 𝑟. 𝑔 (4)
where O is oil level, P is liquid pressure on the upper surface of the transformer, g is gravitational constant of
earth, and r is oil density.

5.2.4. Vibration sensing
To identify any kind of unstable movement at the transformer level, we utilized a SW-420 vibration
sensor. This module includes a potentiometer, a vibration sensor, and an LM393 comparator chip to provide
an adjustable digital output dependent on the amount of vibration. The potentiometer may be changed to alter
the sensitivity to the appropriate amount. When activated, the module produces a logic level high (VCC) and
a logic level low (GND). There is also an integrated LED that illuminates when the module is activated [24].
5.2.5. Microcontroller programing
We used C code to program our microcontroller (DOIT Esp32 DevKit v1) in order to get data from
all the sensors in the system and then send it via Wi-Fi to a cloud environment for the next step of data
visualization. The code was written using Arduino IDE. We imported the ESP32 card library and chose it as
our development board. All the needed libraries such as ThingSpeak and Wi-Fi libraries were also imported.
5.3. Data visualization
After we construct a private channel, where each parameter represents a channel field, all of the
collected data is shown in real time in a ThingSpeak platform interface. message queuing telemetry transport
(MQTT) is the communication protocol utilized between the collecting system and ThingSpeak [25]. The
collected information is processed and graphical representations are created in the ThingSpeak interface.
Users can watch the process of data collection, transmission and visualization in real time as well.
5.4. Data analysis
For this step, we can use MATLAB analysis as ThingSpeak already supports this feature, which can
provide us with further but also basic information about the aggregated data [26]. MATLAB analysis of
recorded data is necessary to see what patterns are occurring and whether or not there are any peaks in the
data. Important information may be derived from the recorded data, such as the highest values, minimum
values, and average values of the various observed parameters. This data may be used to see whether there
are any significant variances in the transformer conditions observed at different times of day. For more
developed analysis, the collected data can be analyzed using other sophisticated tools, but as this paper’s
objective is to only build a monitoring system, we will not get into any deep analysis.
6. RESULTS AND DISCUSSION
6.1. Temperature
We altered the room temperature (we set the cooling system to 16 °C). The aim of this modification
is to test if the surrounding temperature will change as a result. The graph below indicates that after turning
on the cooling system at 16:42, the temperature began to fall until it reached about 16 °C, as shown in
Figure 6.
6.2. Humidity
As we switched on the cooling system, the humidity rose from 53.5% at 16:42 to above 56.5% at
16:52. Which can be seen in Figure 7. When the system turned on, the atmospheric relative humidity (RH)
increased by 3%. This indicates that there was an increase in the moisture level in the air and that our system
is able to detect and record humidity changes.

6.3. Oil level
At first, the oil level was 175 mm; when we reduced it to 150 mm at 17:36, the system displayed the
change in oil level value; for the rest of the time, we kept changing the oil level between 150 mm and
200 mm to see if the system accurately measured the oil level. As a result, we got the graph shown in
Figure 8. This result indicates that the system is measuring the oil level accurately and sending the measures
to our ThingSpeak channel in real time.
6.4. Voltage
Using an adjustable alimentation block, we altered the voltage in the transformer's primary and
obtained a Vsecondary that increases when we raise the voltage in the primary and decreases when we lower
the voltage in the primary. The values we obtained were adequate with the changes in alimentation voltage.
Figure 9 shows the changing values of voltage in decivolts.
Figure 8. Oil level visualization on ThingSpeak Figure 9. Voltage visualization on ThingSpeak
6.5. Vibration
We used a phone vibrating close to our transformer for the vibration test. At 17:14, we raised the
vibration slightly, resulting in a greater vibration value reported on our chart. When we reset the phone
vibration to 19, the chart illustrated in Figure 10 showed a decreasing vibration that reached 19 by 17:18.
This decrease in vibration was due to the change we made. These results indicate that the vibration levels in
transformers are measured in line with our goal.
6.6. Pressure
The pressure imparted to a solid body covered by a liquid is determined by the density and level of
the liquid. We altered the oil level many times, resulting in variable pressure readings presented on the
pressure chart based on how much we varied the oil level. The system gathers pressure measurements in real
time, as shown in Figure 11, indicating that the system is working as planned.

6.7. Discussion
Unlike the systems previously discussed in the introductory section, which do not take into account
all of the conditions affecting the transformer’s performance, the system shown in the results section collects
values of different parameters in real time and reflects any change in the transformer's surroundings. This
monitoring system will provide the monitoring center with the needed information to act at the appropriate
moment before a failure occurs on the transformer’s level. Normal values of all the studied parameters can be
set for the system to generate alerts whenever a value is not within its normal range. The data can also be
used to extract useful information on the changing behavior of environmental conditions in correlation with
each other, which can allow further system development in the future.
7. CONCLUSION
In this study, we built a low-cost, real-time IoT-based monitoring system for power grid
transformers. This system has several advantages since it allows us to gather and display data in real time
with high accuracy at a lower cost with no implementation complexity and, most importantly, it is practical
and feasible. The distance between the monitored transformers and the monitoring center is no longer a
concern because the visualization cloud interface may be viewed from anywhere. Using the collected data,
further analysis may be performed to extract important information about the transformers’ behavior based
on the surrounding circumstances for future purposes, such as designing more efficient cooling systems or
other enhanced systems.
