The purpose of a short-circuit test is to determine the series branch parameters of the equivalent circuit of a transformer.
Why the open-circuit test on a transformer is conducted at rated voltage?
In OC test, transformer is operated at rated voltage at rated frequency so the maximum loses will be the flux in the core. Since the iron or core losses are at rated voltage, the power input is drawn to supply the iron losses by the transformer under no load.
What are the advantages of open and short-circuit test on transformer?
In case of open circuit lest, the power required is equal to the iron loss whereas, for a short-circuit test, the power required is equal to full-load copper loss. (ii) These tests enable us to determine the efficiency of the transformer accurately at any load and p.f. without actually loading the transformer.
