1. Earthing, or grounding, provides greater safety for human life, property, and equipment by providing an alternative path for faulty currents to flow safely into the earth.
2. There are two types of earthing: equipment earthing, which connects the metallic enclosures of electrical equipment to earth; and system earthing, which connects parts of the electrical power system like the neutral point to earth.
3. For stand-alone PV systems, there are three scenarios for equipment earthing: an ungrounded enclosure, an enclosure connected to the neutral wire, or a ground wire connected directly to the enclosure.

PPT on earthing, grounding and isolation made by the students of SVIT,Vasad under the valuable guidance of the faculties teaching us Electronics and Electrical workshop(EEW) under the course of GTU.
A switchgear or electrical switchgear is a generic term which includes all the switching devices associated with mainly power system protection. It also includes all devices associated with control, metering and regulating of electrical power system. Assembly of such devices in a logical manner forms a switchgear. This is the very basic definition of switchgear.

Electrical Safety. Electrical hazards can cause burns, shocks and electrocution (death). Assume that all overhead wires are energized at lethal voltages. Never assume that a wire is safe to touch even if it is down or appears to be insulated.
Earthing, also known as grounding, is based on research that demonstrate that connecting to Earth's electrical energy promotes physical wellbeing. The act of Earthing refers to a physical connection between the electrical frequencies of the human body with that of Earth's (think barefoot in the grass, or at the beach).

Hybrid optimization of pumped hydro system and solar- Engr. Abdul-Azeez.pdffxintegritypublishin
Advancements in technology unveil a myriad of electrical and electronic breakthroughs geared towards efficiently harnessing limited resources to meet human energy demands. The optimization of hybrid solar PV panels and pumped hydro energy supply systems plays a pivotal role in utilizing natural resources effectively. This initiative not only benefits humanity but also fosters environmental sustainability. The study investigated the design optimization of these hybrid systems, focusing on understanding solar radiation patterns, identifying geographical influences on solar radiation, formulating a mathematical model for system optimization, and determining the optimal configuration of PV panels and pumped hydro storage. Through a comparative analysis approach and eight weeks of data collection, the study addressed key research questions related to solar radiation patterns and optimal system design. The findings highlighted regions with heightened solar radiation levels, showcasing substantial potential for power generation and emphasizing the system's efficiency. Optimizing system design significantly boosted power generation, promoted renewable energy utilization, and enhanced energy storage capacity. The study underscored the benefits of optimizing hybrid solar PV panels and pumped hydro energy supply systems for sustainable energy usage. Optimizing the design of solar PV panels and pumped hydro energy supply systems as examined across diverse climatic conditions in a developing country, not only enhances power generation but also improves the integration of renewable energy sources and boosts energy storage capacities, particularly beneficial for less economically prosperous regions.

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.

This is a project with the objective to develop a basic website where a consumer is provided with a shopping cart website and also to know about the technologies used to develop such a website.
This document will discuss each of the underlying technologies to create and implement an e- commerce website.
4. IMPORTANCE OF EARTHING
1.Earthing provides an greater safety for human life, property or equipment.
2.To limit spikes and surges from lighting strikers or other high-voltage condition on
PV.
3.Earthing provides an alternative path to faulty current to flow into the earth.
4. A human body can withstand 30mA for 25ms, and even depends on body of a person.
5. Grounding or Earthing
• The process of connecting the metallic frame (i.e. non-current carrying
part) of electrical equipment or some electrical part of the system (e.g.
neutral point in a star-connected system, one conductor of the secondary
of a transformer etc.) to earth (i.e. soil) is called grounding or Earthing.
Grounding or earthing may be classified as:
• Equipment grounding.
• System grounding.
8. Equipment Grounding
The process of connecting non-current-carrying metal parts (i.e. metallic enclosure)
of the electrical equipment to earth (i.e. soil) in such a way that in case of insulation
failure, the enclosure effectively remains at earth potential is called equipment
grounding.
(i) Ungrounded enclosure
(ii) enclosure connected to neutral wire
(iii) ground wire connected to enclosure.
There can be three scenarios:
16. System Grounding
The process of connecting some electrical part of the power system (e.g. neutral point of a star
connected system, one conductor of the secondary of a transformer etc.) to earth (i.e. soil) is called
system grounding
