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.
