A three-phase 'abe' sequence Y-connected source supplies 14 kVA with a power factor of 0.75 lagging to a parallel combination of a Y-connected load and a A-connected load. The Y- connected load uses 9 kVA at a power factor of 0.6 lagging and has a phase current of 102-30°A. a) Find the complex power per phase of the A-connected load. b) Find the magnitude of the line voltage.
