Question

What is direct loading test on single phase motor?

Answer 1

load test gives accurate results due to actual loading of transformer,whereas in open circuit test we neglect cu losses and in short circuit test we neglect core losses,so readings are not accurate.

2.we can’t predetermine the efficiency and regulation by loading test,which can be obtained by o.c. and s.c. test.

3.for higher rating of loads load test is not suitable,
