Q2] The efficiency of a 6600/384V, 200kVA, 1-phase transformer is 97.5% at full load 0.8 power factor and 96% at 75% of full-load unity power factor. The power factor on no load is 0.25 and the full load regulation at a lagging power factor of 0.8 is 4%. a- draw the equivalent circuit referred to the low voltage side and insert all values. b- calculate the secondary voltage at 80% full-load and 0.8 power factor leading. c- find the maximum voltage regulation at full-load.
