It is because we cannot measure the high current directly.So
for this we will keep CT's to measure high currents.In
primary side it will be 1250A and in secondary side it will
be 50A,this is nothing but CT Ratio.

Which power will flow first if we switch on a motor Active or Reactive? How?

1)we have 1000 cfm Blower,Dia-1Mtr,Velocity of air 94 m/s 2)We have Natural Air velocity 94m/s 3If i Put Wind Mill in natural air ,speed is 94m/s Then it will generate Assume 100kw 4)If i put same wind mill across the Blower,air speed is same 94m/s now the Question is Will it generate 100 kw?
