Pick EITHER Part A or Part B or Part C Part A: A small shopping center contains three stores that represent three balanced three-phase loads. The power lines to the shopping center represent a three-phase source with a line voltage of 13.8 kV rms. The three loads are: Load 1: 400 kVA at 0.9 pf lagging, Load 2: 200 kVA at 0.85 pf lagging, Load 3: 100 kVA at 0.90 pf lagging. Draw the power triangles of each load (15 marks) Find the total 3 phase power at the source (5 marks) Find the single phase power at the source (2.5 marks) Find the line current (2.5 marks)
