What is Earthing?

Earthing is the process by which a component of the electrical system helps remove excessive amounts of current fault perpendicularly to the ground through low resistance wire. Earthing protects human life from the dangers of lightning. Let us take an extensive dive into the factors that affect earthing.


Advantages of earthing

The main advantages of electrical earthing are the following:

  1. Ensures the safety of electrical appliances and devices from the excessive amount of electric current.
  2. Helps in the flow of electric current directly inside the ground.
  3. Keeps the electric appliance safe from the damage
  4. It protects building breakdown from the lightning
  5. It shields from fire occurred due to an electric short circuit and saves goods from fire.
  6. Earthing helps in the protection of overvoltage, stabilization of voltage.
  7. Earthing prevents injury damage and death caused by electric current.
  8. It helps in avoiding the risk of fire in electrical installation systems.

It ensures the safety of electrical appliances and devices from the excessive amount of electric current. The earthing provides the way to default current even after the failure of the insulation. The earthing protects the appliances from high voltage surges and lightning discharge. Earthing keeps the voltage constant in the healthy phase. It ensures the safety from the fire which may be occurred from the current leakage Earthing is used in many industries and sectors such as:

  • Steel plant
  • Solar system
  • Highways
  • Lightening system.
  • Oil Refinery
  • Datacenters
  • Power plants
  • Railways
  • Cement plants
  • Transformers
  • Dg Sets, etc.

Types of Earthing:

These are some main types of Earthing system are found:

1- Plate Earthing:

The plate earthing requires a plate electrode (earth pit ) made of copper or galvanized iron buried vertically more than 10 feet inside the ground. The pit is then filled with salt and charcoal.  The dimensions for the copper plate earthing should be 60cm x 60cm x 3.18mm. The dimension for galvanized iron should be 60cm x 60cm x 6.35 mm.

2- Pipe Earthing:

A pipe earthing system is a pipe made of galvanized steel or iron and buried vertically in the ground. The size of pipe earthing depends on the magnitude of the current and the type of soil which includes moisture soil, sandy soil, rocky soil. Pipe earthing helps in the dissipation of fault current in the electrical system.

3- Rod Earthing:

Similar to the Pipe earthing. A copper rod replaces the pipe electrode. Similar to pipe earthing, the burying of a rod made of copper or galvanized iron these rods are specially designed rods made up of metal and alloys to conduct fault current.

4- Wire Earthing:

In wire earthing, strip electrodes are buried inside these several dug trenches these strip electrodes are made up of copper or galvanized iron. The ground wire provides a path back to the source of the electrical current in the fault current.

5-Waterman method :

The process of earthing in which waterman or galvanized gi pipes is used is known as the waterman method. In this process, the rod is buried inside the ground to reduce resistance.

There are mainly two types of electrical Earthing:

1.Neutral Earthing:

The neutral of the system is directly connected to the earth with the help of GI wire.

These neutral earthing are used in the generator transformer etc.

2.Equipment Earthing:

The equipment earthing is connected to the earth with the help of the conducting wire. If any fault occurs in the apparatus, the short-circuit current to pass the earth with the help of a wire. Thus, protect the system from damage


From the above information, we conclude that earthing is very important for human life as well as for luxurious and expensive electrical appliances.
