hi can you give any body fault level calculation, generator
fault level calculation,transformer fault level calculation
for system fault level with equation? i have 3.3kv
generation voltage three gas gen sets, one is 1.9MW,2nd is
2.5MW,& 3rd is 3.8MW & i have 11 kv generation voltage one
gas gen sets is 3.8MW, we are step up to 22kv by transformer

Answer / dhiren

Hello Rajeshbhai,

You have not mensioned the capacity & impedance of the
transformer

for example if we have

A 5MVA, 11/22KV transformer with a 5% impedance.

Maximum fault MVA will be

5MVA/0.05 = 100MVA
