Reactive power compensation

Thu, 11 Jan 2024 16:40:45 +0100

Reactive power compensation is the process of optimising the efficiency of electricity networks and equipment by reducing the amount of reactive power that must be transmitted through the network. Reactive power is the portion of electrical power that does not perform any useful work, but is necessary to create and maintain electromagnetic fields in electrical machines and equipment.
