Strømfaktorkorreksjon

Strømfaktorkorreksjon, also known as power factor correction, is a technique used to improve the power factor of an electrical system. The power factor is the ratio of real power (kW) to apparent power (kVA) in an AC electrical system. A low power factor indicates inefficient use of electrical power, leading to increased energy costs and potential equipment damage due to excessive heating.

There are several methods to correct the power factor, including the use of capacitors, synchronous condensers, and static VAR compensators. Capacitors are the most common method, as they are simple, reliable, and cost-effective. They work by providing leading reactive power to offset the lagging reactive power in the system, thereby improving the power factor.

The choice of correction method depends on various factors, such as the size of the load, the desired power factor, and the available budget. It is important to consult with a qualified electrical engineer to determine the most appropriate correction method for a specific application.

Regular monitoring and maintenance of the power factor correction system are essential to ensure its continued effectiveness. This includes checking the condition of capacitors, inspecting connections, and verifying the system's performance. By maintaining a high power factor, electrical systems can operate more efficiently, reduce energy costs, and prolong the life of equipment.
