Tehokerroinhyödyllinen
Tehokerroinhyödyllinen is a Finnish term that translates to "power factor beneficial" or "useful power factor." It describes a situation where the power factor of an electrical load is close to unity (1), meaning that the real power (measured in watts) is being effectively utilized. A high power factor indicates that the electrical system is operating efficiently, with minimal wasted reactive power.
In alternating current (AC) circuits, power is divided into real power and reactive power. Real power is
A low power factor, meaning a power factor significantly less than 1, can lead to several inefficiencies.
