RE: pls help for this
I have RMU switchgear connected to transformer 500 kva (package sustation)
And this substation getting supply from main distrbution feeder 11 kv
My question :
When some feeder from the grid station trip the package substation CB trip?
Why the circuit breaker which connected to transformer trip due to other main feeder trip?
I hope my quiestion is clear.
Thanx all.
