Power Factor Correction

Real numbers you can use

When a facility’s kW draw is much less than its kVA (total apparent power), the electrical utility must provide significantly more apparent power (kVA) in order to support the real power (kW) required to supply the facility’s electrical load requirements.

This means that the inductive component of power (kVA-L),
which is typically caused by inefficient AC induction motors (running at little or part load), welding equipment, and large, sudden variations in loads throughout the billing cycle.

As a result, the utility will apply a ‘power factor penalty’ on the user’s bill.

Eliminating the power factor penalty requires a correction, which improves the Power Factor to near unity by introducing Capacitive Power (KVAR-C) to the electric circuit.

The amount of correction is generally based on the measure of the initial power factor ratio. 

Typical ROIs for Power Factor projects can range from 12 to 36 months.
