109.Explain power factor

October 03, 2018 Posted by AK No comments
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

Power Factor (P.F.) is the ratio of Working Power to Apparent Power. = KW/KVA

How to improve power factor

1.Installing capacitors decreases the magnitude of reactive power (KVAR), thus increasing your power factor
2.By using synchronous condenser
