What is reactive power?

The electricity that you receive and consume every day comprises two sorts of power: active power and reactive power. When added together, the result is known apparent power.

  • Active
  • +
  • Reactive
  • =
  • Apparent

Active power is measured in kWh and is the result of transforming electricity into work and heat.

Reactive power is measured in units of kVArh and is generated by the operation of certain electrical devices which use windings that transform energy into electromagnetic fields (engines, transformers, etc.).
