Power factor is a measure of how efficiently electrical
power is consumed. A system with a poor power factor
uses more power than it actually needs, resulting in
high energy bills. Power factor monitoring and the introduction
of corrective equipment may result in significant savings.
When a system is 100% efficient, power factor is unity.
If the power factor is less than unity extra power is
needed to do the same work. Power Factor Correction
(PFC) equipment returns the power factor to as close
to unity as possible thus reducing the burden on the
