Question

(b) When the instruments connected in high voltage side, the short circuit test
readings for 50KVA,5400/240V transformer are 48V.20.8A and 617W.
Find the leakage impedance, effective resistance and leakage reactance
referred to low voltage side​

Answer 1

The main reason for performing the SC test on the HV side is that the rated current will be low in HV side when compared to the rated current in LV side. ... As the rated current flows in the HV winding,the voltage needed to produce the rated current in HV side will be less,so we neglect the (core or iron loss).
