A Factory is supplied froma 3-phase, 4-wire, 400 V, simmetrical system. The resistance of each line is 0.4 Ωand of the neutral 0.6 Ω. The power input to the main is as follows: 10 KVA at a laggin poer factor ofd 0.7 to phase R, 10 KVA at a leading power factor of 0.7 to phase S, and 10 KVA at unity power factor to phase T. Calculate the current in the neutral wire and the voltaje between line R and the neutral at the Factory. Phase secuence RST.
