Transformer Primary side is Delta Connected, so there we
dont provide Earth fault Protection thats why it is not
solidly earthed, only earthing is provide at transformer
body. But on the secondry side which is usually star
connected, we have to provide solidly earthing to neutral
so that we can use earth fault protection system.

When we have earthing mesh or underground earthing network in industrial plants, weather we have NT-S or NT-C-S kind of earthing system, so eventually weather we must use 4 or 5 wire in 400 volt level (For example 3×150+70 mm2 or 5×150 mm2) in this connection I would like to know exactly the paragraph of IEC or IEEE number
