5-Questions :
1- What are the advantages of Transformer Tests?
2- Why is the high voltage winding of single phase transformer is kept open and
measurement made on the low voltage side during no load test.
3- Why are the low voltage winding short-circuited and high voltage excited during
the short-circuit test of single phase transformer.
4- Drive the condition of maximum efficiency of single phase transformer.
5- Why is the iron losses neglected in case if short-circuit test of single phase
transformer.
