Reactive Energy Converter

If you've noticed the idea of reactive energy represented in your power bill, necessary knowledge and calculations are required to understand why reactive energy is sometimes invoiced in extra. 

Reactive energy is nothing but the time integral of the product of voltage and the out-of-phase component of current flow at a point of supply, measured in varhours (varh). The reactive energy consumed is inductive and is billed only during peak and full hours (this period is known as Out of Void hours (PV). In contrast, the reactive energy supplied to the grid is capacitive and is billed during hours of emptiness and super emptiness (this period is known as hours of emptiness). KVArh is the reactive energy unit.

How to convert Reactive energy?

Convert kVAR to MVAR: Reactive power in mega volt-ampere reactive Q(MVAR) equals reactive power Q(kVAR) in kilo volt-ampere divided by 1000. As a result, the formula for converting kVAR to MVAR is,

Q(MVAR) = Q(kVAR) / 1000

MVAR = kVAR / 1000


Calculate the MVAR rating for a 20k VAR Capacitor bank,

MVAR = 20/1000


Hence, 20k VAR capacitor bank = 0.020 MVAR.

Reactive energy units

We provide a total of 5 reactive energy power units. Those are:

  • Volt-Ampere Reactive-hour (VARh)
  • Millivolt-Ampere Reactive-hour (mVARh)
  • Kilovolt-Ampere Reactive-hour (kVARh)
  • megavolt-AmphereReactive-hour (MVARh)
  • Gigavolt-Ampere Reactive-hour (GVARh)
