3 pole short circuit current, 3-winding transformer
(OP)
Hi
I have a 3-winding transformer Delta/Wye/Delta rated 2500/1250/1250 kVA, Zk= 6% and voltage 6300 V/690 V.
My question is how do I calculate the maximum 3 pole short circuit current on the Low voltage side ? Must I use 1250 kVA for power or 2500 kVA (and why)
