mag. current is tested to see whether all the 3 phases are
properly magnetised or not.If any phase is taking a higher
current then it could be said that in that phase some
conductors are short,So it's better that during this test
variac be used to apply the voltage,one should slowly
increse the voltage or just on-off the multimeter used to
see the quick response,if current is quickly incresing use
variac,to protect the multimeter.

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?
