Two balanced three-phase loads are supplied by 840 Vrms, 60hz line as shown below. Load 1 is wye-connected with 30 + j40 ohms per line. Load 2 is a three-phase motor drawing 48kW with a PF of 0.8 lagging. V=840 V (Rms) Balanced load 2 Balanced load 1 (a) Capacitors for pf Correction Combined load a) The total complex power is kVA Degrees. Write your answer in numeral form without units rounded off to two(2) decimal places. b) The KVAR rating of the three delta-connected capacitors connected in parallel with the load as shown in fig (b) to raise the PF of the system to unity is KVAR. Write your answer in numeral form without units rounded off to two(2) decimal places. c) The total current drawn from the supply line at unity PF is Amps. Write your answer in numeral form without units rounded off to two(2) decimal places.
