A Millivolt-Ampere Reactive Hour (mVARh) is a unit of measurement for a specific type of electrical energy called reactive energy.
Put simply, it's a tiny unit, equal to one-thousandth of a Volt-Ampere Reactive Hour (VARh).
It's used when measuring small amounts of reactive energy, allowing for exact and precise calculations.
To understand mVARh, you first need to know about reactive energy. In an electrical system, you have two types of energy:
Real Power (measured in Watts): This is the energy that does actual work, like lighting a bulb or spinning a motor.
Reactive Power (measured in VARs): This is "wasted" energy that is stored and released in the circuit. It's necessary to create the magnetic fields that devices like motors and transformers need to run. Still, this energy doesn't perform the final "work."
A simple analogy is a glass of beer. The liquid beer is the real power—it's what you actually drink. The foam on top is the reactive power. You need the foam to complete the beer, but the foam itself doesn't quench your thirst.
A Millivolt-Ampere Reactive Hour (mVARh) is a unit that measures the flow of this reactive "foam" over a period of one hour.
The "milli" in mVARh means one-thousandth.
It's a subunit of the more common Volt-Ampere Reactive Hour (VARh), just like a milliliter is a subunit of a liter.
The conversion is straightforward:
Since a VARh is often too large for specific applications, the mVARh unit exists for more granular measurement.
Using this smaller, standardized unit (as part of the International System of Units, or SI) is essential for:
Precision: It allows engineers to be highly accurate when designing and analyzing small-scale electrical circuits.
Energy Billing: Utility companies sometimes use it to measure and bill for reactive energy consumption, as too much reactive power can be inefficient for the grid.
Technical Standards: It ensures that electrical measurements are consistent and understood by professionals worldwide.
A Kilovolt-Ampere Reactive Hour (kVARh) is the standard unit used to measure reactive energy.
It is a larger multiple of the base unit, the Volt-Ampere Reactive Hour (VARh).
1 kVARh = 1,000 VARhReactive energy is often called "wasted" or "non-working" power.
Here's a simple comparison:
A high kVARh reading indicates a low power factor, which means your electrical system is inefficient.
It's drawing more current from the grid than it actually needs to perform the useful work.
Many utility providers, especially for commercial and industrial customers, issue penalties for high reactive energy consumption.
High kVARh levels force the utility to generate and transmit more current to meet your demand, which puts extra strain on their transformers and distribution lines.
These costs are then passed on to you, often appearing as a "power factor penalty" or "reactive power charge" on your monthly electricity bill.
You can lower your kVARh consumption through a process called power factor correction.
The most common method is installing capacitor banks, which act as local reactive power generators. By supplying this energy on-site, they reduce the amount of reactive power you need to pull from the grid.
