Answer / abhishek goyal

Its related to short circuit current because of that when we
design any plant and there electrical system. design
engg.(first calculate the total load)calculate the max SC
current according to that equipment will be select. Its
called the fault level:
it divided into 2 (Major):
low fault level (for normal equipment)
high fault level (for critical equipment)
as per total load of plant or capacity.

Answer / sakthivel

in our electrical system no of fault available there are
1,open circuits 2,short circuits 3,loose connections 4,earth
faults if any fault depends on voltage and full load current
and insulation cable so that is not idea,

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.
