I am working on a 11KV system with fault current of 40KA
for 1 second. I have selected 2500MVA 11/0.433KV
transformer.
How can i find the impedance value for this transformer?
Please help me.
Answer Posted / wareagle
First I do not believe an 11 kv system can have a 40ka
fault. You need to check again.
Second I do not believe you can connect a 2500 mva
transformer to an 11 kv system. Maybe 2500 kva.
%Impedance is on the nameplate of the transformer or ask
the manufacturer.
