Capacitor absorbs reactive power

Reactive power of capacitors

Inductive-reactive power is conventionally positive (absorbed by an inductive load), while capacitive-reactive power is negative (supplied by a capacitive load). As reactive-inductive loads and line reactance are responsible for voltage drops, reactive-capacitive currents have the reverse effect on voltage levels and produce …

Introduction to STATCOM Systems

The out-of-phase power is called reactive power and is designated volt-amp reactive (VAR)—the unit adopted in 1930 for reactive power. In an AC system, the power factor is defined by the ratio of real power used by a load to the apparent power in the circuit—A system with a lower power factor will have higher amounts of energy …
