The equivalent impedance referred to the primary of a, Ask an Expert

Engineering

The equivalent impedance referred to the primary of a 23001230-V, 500-kVA, single-phase transformer is

Calculate the percentage voltage regulation (P.V.R.) when the transformer delivers rated capacity at 0.8 power factor lagging at rated secondary voltage. Find the efficiency of the transformer at this condition given that core losses at rated voltage are 2 kW.
