A Volt-Ampere Reactive Hour (VARh) is the standard unit used to measure reactive energy.
Think of reactive energy as "helper" energy. In an electrical system, you have two fundamental types of energy:
While reactive energy doesn't do the "work" itself, it's essential for this equipment to function.
Tracking VARh is the key to measuring your system's electrical efficiency.
A high VARh reading on your utility bill is a direct sign of a low power factor. A low power factor means your electrical system is inefficient.
Power companies often charge utility penalties for a low power factor because this high demand for "helper" energy puts extra strain on the electrical grid.
Because of this, many businesses monitor their VARh and use power factor correction strategies.
This often involves installing capacitor banks (a type of energy-saving device) to reduce reactive energy, avoid utility penalties, and lower their overall energy bills.
Managing VARh is vital for both utility providers and large consumers to keep the power grid stable and reliable.
For Utility Providers, controlling VARh helps:
For Consumers, managing VARh helps:
