Answer / patel rakesh i

The meaning of synchronous in 'synchronous machine' is it's
rotor is rotating at constant speed.

Answer / vishal

when there is no slip between rotor speed and speed of
rotating magnetic field. then we call motor as synchronous.
if slip is there then motor is induction type.

Answer / devanshu tiwari

At a constant speed by the supply frequency and the number
of pole

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.
