L-G Short circuit Topology
L-G Short circuit Topology
(OP)
Thanks,Mpparent,
I don't have a specific system topology. I can think about a typical one right now.
One ulility line U1 is feeding a plant through a 34.5/13.8KV transformer(DELTA/WYE-G),A MOTOR IS CONECTED TO 13.8KV bus through a trans( 13.8KV/ 4.16KV wye-g/wye-g), A generator is feeding 13.8KV bus through a 4.16/13.8KV Trans(wye-g/wye-g ). A L-G fault is expected on 13.8KV Bus.
I am wondering what kind of data I should acquire from Manufacturers and utility,especiallly for zero sequence data.
Thanks.

I know It is a bit difficult for any electgrical engineer.But I just want to clarify some methodologies through short-circuit studies.
