Hi If connecting a temp generator 670KVA .415kv with step up Tx .415/11kv. I am given Generator impedances Z1 Z2 Z0 to 100MVA base. Do I need to work out the generator fault current by using these impedances i.e gen rating / impedance. Then use this as my source impedance for the calculations that follow.
