A delta-star connected three phase transformer 50 Hz, has 24,000 Volt and 400 Volt as line voltages. The secondary side of the transformer is connected to a star balanced load at 80% power factor, which is in lagging nature. Assume the value of 6 A as the line current on the primary side of the transformer. Find the values of the current in primary and secondary line. Also determine the output power of the transformer in kilo-watt?
