Question

Power required during the open circuit and short circuit test is?

(a) losses incurring in the transformer

(b) executing the power requirements by measuring instruments

(c) power for the core losses only

(d) all of the mentioned

The question was asked during an interview.

I'd like to ask this question from Open Circuit and Short Circuit Test topic in division Transformers of Electrical Machines

Answer 1

Right option is (a) losses incurring in the transformer

Best explanation: The power measured while conducting the tests is the winding losses and the core losses.
