A 5000 kVA, 12000/30000 V single-phase transformer draws 15 kW and 12 A when idling and has short-circuit parameters ZccL = 1.25 _ and RccL = 0.125 _. Decide:to. Rsc, Xsc and Rfe parameters of the equivalent circuit referred to the secondary.b. relative voltage drops. Ecc, Ercc, Exccc. The voltage in the secondary when the primary is connected to nominal voltage and the transformer supplies a load of 4000 kVA fp = 0.75 inductived. The efficiency when feeding a 3500 kW load fp = 0.8 inductive
