8.1-A Y-connected balanced three-phase source is feeding a balanced three-phase load. The voltage and current of the source coil are: v(t) = 340 sin(377t + 0.5236) V i(t) 100 sin(377t + 0.87266) A = Calculate the following: a. The rms phase voltage. b. The rms line-to-line voltage. c. The rms current in the source. d. The rms current in the transmission line. e. The frequency of the supply. f. The power factor at the source side, state leading or lagging. g. The three-phase real power delivered to the load. h. The three-phase reactive power delivered to the load. i. If the load is connected in delta configuration, calculate the load impedance.
