Definitions:

Inductive VARs

In power systems, inductive VARs (Volt-Ampere Reactive) are reactive power components generated by inductive loads, contributing to the overall power factor but not to the actual work performed.

Power Factor

A dimensionless measure of how effectively electrical power is converted into useful work output, particularly the ratio of real power to apparent power in a circuit.

Capacitive VARs

Reactive power measured in Volt-Ampere Reactive (VAR) generated by capacitive loads, which can be used for power factor correction in electrical systems.

Power Factor

An indication of the efficiency with which electrical power is turned into actual work, measured on a scale from 0 to 1, where a value of 1 signifies the highest possible efficiency.
