Answer / k.prakashchandra

If the load is 100 A ,the meter records correctly if the CT ratio is 100/5 as the meter gets 5A current . If the CT ratio is 600/5 the current in the meter will be 5/6 A for the same load current . Hence to get the correct reading ,multiply by 6.

During the main stator winding insulation testing (phase to ground)of 11kv alternator (Lerysomer) i found 0 and resistance with multimeter and found 20 killo ohm while the power cables are connected both end (Generator & VCB). In VCB PT (Potential transformer) are connected. Please any body explain that method of insulation is correct or not? also describe of PT connections
