The earthing conductor must be as short and straight as possible in its run be of phosphor bronze or high conductivity lined copper. It should not be less than half the sectional area of the largest cable being protected provided that it need not be larger than 0.6 Sq. cm in sectional area. No joints are permitted in the earthing cable.
Now a days, earth-pits are most common method for earthing, especially for electrical networks. Electricity always follows the path of least resistance. To divert the maximum current away …
In an electrical installation or an electricity supply system an earthing system or grounding system connects specific parts of that installation with the Earth's conductive surface for safety and functional purposes. The point of reference is the Earth's conductive surface, or on ships, the surface of the sea.
In this video we are going to discuss about Earthing pit construction and procedure
May 09, 2020· Constructing and Maintaining an Earth-Pit Nowadays, earth-pits are the preferred method for earthing, especially for electrical networks. Electricity always follows the path of least resistance, and to divert the maximum current away from a circuit, earthing pits are designed to reduce ground resistance, ideally to 1 ohm. Read More
The size of the pipe depends upon the current to be carried and type of soil. Normally, the size of the pipe uses for earthing is of diameter 40 mm and 2.5 meters in length for ordinary soil or of greater length in case of dry and rocky soil. The depth at which the pipe must be buried depends on the moistures of the ground.
C. Earth Pit: Precast, square or circular section concrete handhole (minimum 450 mm internal diameter), with ultra heavy-duty cover for areas where heavy vehicles cross, and extending to about 150 mm below top of earth rod. Earth pit is to be provided for each earth rod where connected to an earthing conductor.

Pipe earthing uses 38mm diametre and 2 metres length pipe vertically embedded in the ground to work as earth electrodes. In plate earthing, an earthing plate made of copper or G.I. is buried into the ground at a depth more than 3 metres from the ground level. This earthing plate is embedded in an alternative layer of coke and salts.
1) Install an earth pit. 2) Insert plate electrodes. 3) Make earthing and water connections. 4) Backfill the pit and build an inspection chamber. EARTH PIT: Excavation happens at a feasible spot in the substation, and an earth pit of minimum size 900mm x900mm and a depth of 3m below the surface is created. PLATE ELECTRODE:
