There are earthing transformer directly connected from 11kV switchboard and earthing transformer is of Wye(neutral grounded)-Delta(broken delta with resistor). However, I did not find connection from neutral point of generator. This is first experience to me.
First, I am not sure if earthing function works.(In this case no neutral earth is required)
Second, how earth current loop is made at earh fault at either generator side of any bus.
Third, Circuit Breaker will trip at earth fault at any rate ?
I need to further study this earthing system. Welcome to advise...
