To understand power factor, we’ll first start with the definition of some basic terms:
KW is Working Power (also called Actual Power or Active Power or Real Power).
It is the power that actually powers the equipment and performs useful work.
KVAR is Reactive Power.
It is the power that magnetic equipment (transformer, motor and relay) needs to produce the magnetizing flux.
KVA is Apparent Power.
It is the “vectorial summation” of KVAR and KW.
So, now that we understand some basic terms, we are ready to learn about power factor:
Power Factor (P.F.) is the ratio of Working Power to Apparent Power.
Great. I now understand what power factor is. But I’ve been told mine is low.
What did I do to cause this?
Since power factor is defined as the ratio of KW to KVA, we see that low power factor results when KW is small in relation to KVA. Remembering our beer mug
analogy, this would occur when KVAR (foam, or Mac’s shoulder height) is large.
What causes a large KVAR in a system? The answer is…inductive loads. Inductive loads (which are sources of Reactive Power) include:
􀂉 Transformers
􀂉 Induction motors
􀂉 Induction generators (wind mill generators)
􀂉 High intensity discharge (HID) lighting
These inductive loads constitute a major portion of the power consumed inindustrial complexes.
You want to improve your power factor for several different reasons. Some of the
benefits of improving your power factor include:
1) Lower utility fees by:
