Answer Posted / sudhakar g
For any transformer it is better to install two for body
eathing and two for Neutal earthing
Body Earthing: GI pipe 40mm dia using charcoal and salt
like this
Neutral Earthing: Copper plate 600x600x3 mm size for
netural earthing with all neccesary materials
After completion of Earthing you need to check the earth
resistance value for these earthing it should be below 3ohms
I think these are the neccasary requiremnts for your
trasnformer
According to IS standards the distance between pits must be
2.5mtrs and from the building it should be far from 3000mm
