What is Reactive Power ? The rational use of electrical energy calls for economical generation, transmission and distribution with little loss. That means restricting all factors in electrical networks that cause losses. One of these factors is lagging reactive power. Consumers in industrial and public electrical networks are primarily of an ohmic-inductive nature.                           

What is Power Factor Correction (PFC)? The purpose of systems for power factor correction in networks is to compensate the generated lagging reactive power by leading reactive power at defined nodes. In this way impermissibly high voltage drops and additional ohmic losses are also avoided. The necessary leading power is produced by capacitors parallel to the supply network, as close as possible to the inductive consumer
