No Shortcut, No skipping, and detailed as possible6. FINAL ANSWERS must be rounded up to three decimal places PROBLEM:A three-anode mercury-arc rectifier supplies a 250-kw 230-volt load and is energized from a 4,600-volt three-phase source through a three-phase transformer whose primaries are in delta. Assuming an arc drop of 20-volts, calculate:(a) the d-c load current;(b) the voltage and kilovolt-ampere rating of each transformer secondary;(c) the current and kilovolt-ampere rating of the three-phase transformer.

FINAL ANSWERS must be rounded up to two decimal places with corresponding unit. PROBLEM:The polarity test is performed upon a transformer. If the input voltage is Vin and the voltmeter readings are 121.8 volts (additive) and 110.2 volts (subtractive). Calculate the turns ration.
