What is the effect if power factor is above 1 or unity.
Answer Posted / muhammad tahir khan
A power factor of one or "unity power factor" is the goal
of any electric utility company since if the power factor
is less than one, they have to supply more current to the
user for a given amount of power use. In so doing, they
incur more line losses. They also must have larger capacity
equipment in place than would be otherwise necessary. As a
result, an industrial facility will be charged a penalty if
its power factor is much different from 1.
