A transformer with 10: 1 rato and rated at 50 KVA, 2400 7 240 V, 50 Hr is used to step down the voltage of a distrbution system. The low-tension voltage is to be kept constant at 240 V i. What load impedance connected to the low-tension side will be loading the transformer fully at 0.8 power factor lagging? ii.What is the value of this impedance referred to high-tension side? iii. What is the value of this current referred to high-tension side?
