What are kW and kVAR?

Active power—or kW—is the one that supplies the energy for heat, sound, motion, and light.

Reactive power, on the other hand, is inductive and is the energy that powers magnetic fields that are essential in rotating equipment.
So, if something in the equipment moves, it’s likely operating under the inductive load. These are often in the form of compressors, refrigerators, freezers, motors, washers, dryers, dishwashers, pool pumps, and computer fans along with furnace blow motors, air conditioning units, well pumps, ceiling fans, and more.
