Presentation Outline

3. Introduction
 Internet of Things (IoT) is a system of devices connected to
the internet with the ability to collect and exchange data from
users or environment with no human intervention.
 The device or the “thing” in IoT could be any device embedded
with electronics, software and sensors.
 A protective relay is a switchgear device that detects the fault
and initiates the operation of the circuit breaker to isolate the
defective element from the rest of the system.
 IoT enables relay to be controlled easily via internet from
anywhere.

4. Literature survey
Paper Achievement Research gap
1. Smart circuit
breaker using IoT
technology [1]
The circuit system is
manually controlled
by Blynk application
It is not interface with
GSM modem
The overall circuit
performance is
maintained while
reducing maintenance
cost and unnecessary
downtime
Remote controlling
feature is not available
2. Password based
circuit breaker [2]
Proposed a system
that focuses on the
safety of linemen
while working
Since it contain GSM
modem, it should
have sufficient
balance or data plan
The lineman detects
fault in the electric
line. SMS gets sent to
the substation staff
who then switches off
the line
It can not control
other areas beside the
substation

5. Paper Achievement Research gap
3. Power-system protection
device with IoT based
support for integration in
smart environments [3]
The proposed system
enhances
electrical safety by fast
disconnection of the power
supply in case of fault
events
Integrating the protection
device in the smart city
infrastructure with LoRa
(Long Range Wide-area
network)
It enables real-time
monitoring and notification
events
through an advanced
communication interface
using a data concentrator
architecture
integration of the ELSA
device in power grids with
distributed energy
generators for identifying
and addressing potential
technical issues
4. IOT Based Circuit Breaker
Monitoring & Control [4]
It will reduce the
size of the circuit breaker
EMI/EMC compliance test is
not performed
It will eliminate the
concern regarding security
vulnerability of third party
Integration with
computerized maintenance
management

6.  Nowadays, electrical accidents of linemen are increasing day
by day due to electrical shocks while repairing the electrical
lines.
 This happens due to the lack of communication between the
electrical substation and maintenance staff.
 This IoT based relay system provides real time monitoring and
controlling capabilities.
 It enables remote power cut-off.
 Danger of accidents and electrocution can be greatly
minimized.
Project motivation

7. Objectives
 To monitor line status live from remote location.
 To eliminate the use of fuse which are comparatively
slower as they mechanically break the circuit.
 To be able to detect when and where fault occurs.
 To be able to control circuit breaker status remotely with
mobile app or web platform.
 To be integrated in smart environments like smart homes
or smart cities for protecting the electrical equipment.

8. Proposed Model
fig: block diagram of the
system

9. Operating principle
1. Node MCU is used as it has micro controller with free Wi-Fi
module.
2. Relay Module is reliable for AC load.
3. LCD display is used for displaying the status of Load.
4. IC 74HC595 is used for utilizing only 3 pins of Node MCU.
5. A 9V battery is used to power Node MCU. It can also be
powered by Laptop or PC using USB.
6. Load here can be any AC – devices.
7. MQTT protocol and MQTT broker is used to monitor the
status and control the state (ON/OFF) of the connected loads
remotely.
