kWh of energy

1. If a 480-V supply delivers 50 A with a power factor of 0.8, find the real power (kW), the reactive power (kVAR), and the apparent power (kVA). Draw the power triangle.

2. Suppose a utility charges its large industrial customers $0.04/kWh for kWh of energy plus $7/month per peak kVA (demand charge). Peak kVA means the highest level drawn by the load during the month. If a customer uses an average of 750 kVA during a 720-hr month, with a 1000-kVA peak, what would be their monthly bill if their power factor (PF) is 0.8? How much money could be saved each month if their real power remains the same but their PF is corrected to 1.0?
