What is Power Factor Correction?
Power Factor Correction, or PFC as it is often referred to is designed to reduce reactive power (kVAr) and improve the ratio between useful power (kW) and true power (kVA). In most cases, poor power factor is caused by inductive loads, such as motors. This can be compensated by introducing electrical devices called capacitors into the circuit.
Power Factor Correction is normally installed on the incoming electrical supply and reacts to load fluctuations, bringing capacitors into circuit as the load requires. You simply set a target power factor and the automatic controls do the rest, ensuring the best possible power factor is achieved regardless of how the load fluctuates.
Power Factor Correction is connected in parallel to the main incoming supply meaning there is no need for a shutdown of your supply for installation and no disruption to your day to day business.
