The O.C and S.C test data are given below for a single phase, 5 kVA, 200V/400V, 50Hz transformer.
O.C test from LV side:200V 1.25A 150WS.C test from HV side:20VV 12.5A 175W
Draw the equivalent circuit of the transformer (i) referred to LV side and (ii) referred to HV side inserting all the parameter values.
