Tutorial on AC Power - Part 1

In this tutorial, you will use the volt-ampere method to calculate power parameters of an AC circuit.

A factory uses 220V commercial power. The principal users of power are a lighting load of 200 kW and an injection molding machine rated at 600 kVA. The molding machine has a power factor of .63 lagging and is 87% efficient in converting electrical energy to mechanical energy.

Draw the power triangle for the molding machine.

What is P for this power triangle? Round your answer to the nearest kilowatt.
