1- Electrical Earthing:

Electrical earthing is a safety system which is protects humans and equipments from leakage current. Electrical earthing is connected to the body of equipments. During current leakage, the current should be immediate discharge into ground through low resistance earth wire and earth electrode. This process is called electrical earthing. Different types electrical earthing are used.

3- Parts of Earthing

1- Earth Pit:

Earth pit is the main part of ground where earth electrode is connected to the distribution earth wire or strip.

2- Earth pipe or Strip:

Earth pipe or strip is connected to the earth plate for current discharging.

3- Earthing Plate:

Earthing plate is used for discharging the current quickly into ground.

4- Earthing wire:

Earthing wire is used for current discharging from equipment to earth pit.

4- Types of Earthing:

A- Construction type:

• 1- Pipe Earthing
• 2- Rod Earthing
• 3- Plate earthing
• 4- Chemical Earthing
• 5- Conductor Earthing

B- Connection type

• 1- Neutral earthing
• 2- Equipment Earthing.

5- Importance of electrical earthing:

Earthing is most essential part of electrical system so it has more importance points as per below mentioned.

• Protect any human from electrical shock during leakage current equipment body.
• Protect to the electrical equipment form any short circut before insulation failure.
• protect to the high rise building and electrical system from sky lightning.
• protect to the electrical equipment from fire case.
