Question on fault current

[coulter]

i would not feel comfortable making any recomendation. Maybe you could look at Bussman's website software.

I'm curious as to how this comes out, but I need to know;

1. What is the voltage on the HV side of the transformer?
2. What is the (R and X values of short circuit impedance) or (X/R of the system and impedance Z)? This info will come from utility. You cannot do calcs without it.
3. What is the actual size (KVA) of the transformer and impedance of the transformer?
