Two electric furnaces are supplied with 1- phase current at 80V from a three phase,11 KV
system by means of two single-phase Scott connected transformers with similar secondary
windings. When load on one furnace is 0.5 MW (teaser secondary) and on other furnace is 0.8
MW (Main transformer secondary).
What current will flow in each of three phase lines at
i) Unity power factor
ii) 0.5 power factor
