A Megavolt-Ampere Reactive (MVAR) is a unit used to measure reactive power in an electrical system.
Think of it as a measurement for a type of "unproductive" power that doesn't do real work, but is still essential for the system to operate.
One MVAR is equal to one million volt-amperes reactive (VAR).
MVAR is a key measurement used in power factor correction. Here's a simple breakdown:
Essential but "Unproductive": Some equipment, like motors and transformers, need reactive power (measured in MVAR) to create magnetic fields just to run.
The Problem: This reactive power doesn't do any useful work (like turning the motor's shaft). High levels of MVAR in a system lead to a "poor power factor."
Why It's Bad: A poor power factor is inefficient. It causes wasted energy, higher electricity bills, and extra strain on the electrical grid.
The Solution: Utility companies and large facilities install equipment (like capacitor banks) to balance these MVARs. The goal is to get the power factor as close to 1.0 (or 100%) as possible, which is the most efficient state.
It's easy to confuse reactive power (MVAR) with "real" power, which is measured in Megawatts (MW).
Megawatts (MW): This is the "real" or "active" power. It's the power that does useful work, like lighting a bulb, heating a room, or turning a motor's shaft.
Megavolt-Amperes Reactive (MVAR): This is the "reactive" or "unproductive" power. It doesn't do useful work, but it's still essential for creating the magnetic and electric fields that allow many types of AC equipment to operate.
Beyond efficiency, balancing MVARs is fundamental for maintaining voltage stability across the electrical grid. Think of it as managing "pressure" in the system.
Too Few MVARs: An inadequate supply of reactive power causes the system's voltage to drop. This can lead to "voltage sag" (like dimming lights), equipment malfunction, or even blackouts.
Too Many MVARs: An excess of reactive power causes "over-voltage." This high-voltage condition can damage sensitive electronics and equipment.
Grid operators constantly manage MVARs to keep the voltage stable and ensure you receive reliable electricity.
A Kilovolt-Ampere Reactive (kVAR) is a unit used to measure reactive power in an electrical system.
One kVAR is equal to one thousand volt-amperes reactive (VAR). Think of it as the counterpart to a kilowatt (kW), which measures real power (also known as "working power").
kVAR measures reactive power, often called "non-working" power or "wattless" power.
While it doesn't perform actual work (like lighting a bulb), it's essential for equipment that uses magnetic fields to operate. This includes common industrial and commercial items like:
This power is "reactive" because it just moves back and forth (oscillates) between the power source and the load. This extra movement increases the total current in the wires, which can put a strain on the entire electrical system.
A high amount of kVAR is the primary cause of a poor power factor.
Power factor is a critical measure of your electrical efficiency, on a scale from 0 to 1. A low power factor score means your system is using energy inefficiently.
To fix this, buildings install power factor correction (PFC) systems, which are usually capacitor banks. These banks supply the needed reactive power directly to the equipment.
This process "cancels out" the reactive power that would otherwise be pulled from the utility grid, which provides several key benefits:
Excessive kVAR is bad for both your system's health and your wallet. Because it increases the total current flowing through your wiring, high kVAR leads to several significant problems:
To cover the costs of this strain on the grid, utility companies often charge demand fees or power factor penalties, especially for commercial and industrial customers.
