The capacity of the transformer is 20/25 MVA, Ratio is
132/11 KV, Vactor group YNyno. and impedance is 10.07%. As
per the calculation the secondary current is 1312.2Amps.
The maximum fault current the transformer should sustain is
13.030KA. How many times the transformer should sustain the
maximum short circuit current of 13.030KA over a period up
1 Year. The transformer is repaired one & 10 Years old.
