How are Plate Earthing & Pipe Earthing done?

How are Plate Earthing and Pipe Earthing done? | How Do Plate Earthing and Pipe Earthing?

Earthing is very important in every electrical installation. But how is this Earthing done? In this article, we have explained closely.

2 Types of Earthing

  1. Plate Earthing
  2. Pipe Earthing

Plate Earthing

Plate Earthling

In the name of this type of Earthing, we can understand that a Plate of metal is used in it. Copper metal for Plate Earthing or G.I. Plate is used.

To make a Plate Earthing, a 90 × 90 cm pit is dug deep up to 3 meters in the ground.

Pipe Earthing

Pipe Earthing

A pit is made 70cm long, 70cm wide and 3.75 meters deep in the ground for Pipe Earthing. a G.I., 38mm in diameter and 2 meters long. The Pipe is used as the earth electrode in that pit.

The entire surface of that Pipe has 12mm holes. Which are made at a spacing of 7.5 cm. This means the electrode is fitted with a reducing socket with a diameter of 19mm and two such 12.7mm diameter G.I. Pipes are connected.

A funnel is attached at the top end of the 19mm diameter Pipe. The funnel is used to water the Earthing. An open conductor for the earth lead is connected to the earth electrode through a 12.7mm diameter Pipe.

The purpose is that the earth lid should not be damaged anywhere.

Earth is laid around every layer of electrode at an interval of 15-15cm with sandy, sand and coal layer by layer.

Meaning the pit above the electrode is covered with soil.

The earth conductor, which is lifted out of a Pipe of 12.7mm diameter, is carried forward 60 cm below the ground, to the place where Earthing is to be done.

A 30 × 30 cm cement concrete tank is built around the funnel. It is covered with a lid of cast iron.

This type of Pipe is used for wiring installation of Earthing low and medium voltage.
