Question

Why no load test done on low voltage and sc on high voltage side?

Answer 1

heyyy broo

the reason is that:

1....for LV side, rated voltage required will beless compare toHigh voltage side. so low range voltmeter and wattmeter sufficient to conduct the test...

2...In no load test,no load currentis only 4 to 6 percentage of full load current, so forLV side rated current is high and no load current whuch only 4 or 6 percentage willbe high compare to no load current in case of high voltage winding. So that's why no load current can be accurately measured....
