KILOVAR Meaning and
Definition
-
A kilovar is a unit of electrical reactive power in the International System of Units (SI). It is abbreviated as kVAR and is equivalent to 1000 volt-ampere reactive (VAR). Reactive power represents the power that oscillates between the source and the load in an alternating current (AC) system, without being converted into useful work.
Kilovar is primarily used in the field of electrical engineering to measure and quantify the reactive power of a system or device. Reactive power is necessary for the operation of inductive devices, such as electric motors, transformers, and fluorescent lamps. It is denoted as the product of the voltage (V) and the reactive current (I) in a circuit.
One kilovar is equal to the reactive power of a perfect inductor or capacitor that takes one kilovolt-ampere (kVA) to create a 90-degree phase shift between voltage and current. It is important to manage and control reactive power in electrical systems to maintain voltage stability and to optimize the power factor, which measures the efficiency of a system in converting electrical power into useful work.
By measuring and controlling kilovar, engineers are able to ensure the smooth and efficient operation of electrical systems, preventing issues such as voltage sags, equipment overheating, and unnecessary energy consumption.

Etymology of KILOVAR
The word "kilovar" is a combination of two components: "kilo" and "var".
- "Kilo" is a prefix derived from the Greek word "khilioi" meaning a thousand. It is used to indicate a factor of one thousand in the metric system. For example, kilogram represents 1000 grams and kilometer represents 1000 meters.
- "Var" is short for "volt-ampere reactive". A volt-ampere reactive is a unit used to measure reactive power in electrical circuits. Reactive power is the power consumed in an AC circuit due to reactive components like inductors and capacitors.
Combining these two components, "kilovar" represents a thousand volt-amperes reactive, or 1000 VARs.
