Answer / rajendran

This value is very important....

1) For calculating the fault level of the system....
2) To determine the load sharing !!!!!!! during parrellel
operation of the transformer....

Answer / rajeshsan

The Transformer impedance plays a major role in power system.

The Transformer impedance will reduce the fault current. If there is high impedance transformer placed between the circuit. The transformer will acts as isolation to fault current.

Answer / sanket
