What is Electrical Grounding / Earthing | Electrical Grounding Explained | Animated Lecture
Control Panel grounding explained
Motor grounding explained
~
In this video you will learn what is electrical earthing, how to earth control panel and electrical motor etc. What are benefits of earthing and what will be result if you don’t earth any control panel, we will show with animations and videos any body with little background of electronics or electrical will be easily able to understand these concepts after watching this. You will see videos from industry how electrical earthing is in practical for control panels and motors. There is big surprise if you watch this video till the end.
Lets start with what is Electrical earthing.
To connect the metallic Parts of an Electric appliance or installations such as electrical control panels or electrical motors to the earth (ground) is called Earthing or Grounding.
Earthing can be said as the connection of the neutral point of a power supply system to the earth so as to avoid or minimize danger during discharge of electrical energy
To understand why it’s important lets understand it with simple example.
Normally we got three wires of power connections in any control panel i.e. Hot, natural and ground. Let’s suppose if hot (Live) wire of control panel gets damage and it will touch the metal case of control panel. Case is now connected to hot wire. Now if any field worker touches panel, he will get get strong electrical shock. This is because current have path that’s via human body to ground

Now if you got another arrangement, where ground wire is connected to electrical control panel case. Ground wire will offer very low resistance path to flow of current, current will flow from panel to ground via earth wire instead of human body which have more resistance compare to ground wire. Please note current always flow to least resistance path ,as we connect live(hot) wire via breaker, In such cases current will increase due to least resistance on that path and it trip the breaker that will discounted power. Now if field engineer or tech touches such panel, he will be protected as human body have more resistance as compare to other path of offered by ground wire.
