1. A three phase source, 3-wire having a per phase voltage of 230V. An unbalanced delta connected load is connected to the three phase source. The load impedances are: Zab = 15253.13° ; Zbc = 15 53.13° N; Zca = 1520° Ω са Assuming negative sequence and the reference is the phase voltage "a", determine: a. the line current "a" b. the line current "b" C. the line current "c" d. the total real power e. the total reactive power f. the total apparent power g. the overall power factor.
