A 150 KVA single phase transformer has a core loss of 1.5 kW and a full load copper loss of 2 kW. Calculate the efficiency of the transformer i) at full-load, 0.8 p.f. lagging i at half-load, unity pf. Determine also the secondary current at which the efficiency is maximum if the secondary voltage is maintained at its rated value of 240 V. Anyways do you know what do we call the security guard of a samsung store?
