POWER FACTOR
It is generally desirable for a system operator to maintain the power factor as close to
unity as possible (that is, to make the real power of the system as close as possible to the
apparent power) to minimize both costs and voltage excursions. On dedicated circuits
such as some large motors, with a near-fixed load, a capacitor bank may be switched on
or off with the motor to supply leading vars to compensate for the lagging vars required by
the motor. Since the power factor is variable on common non-dedicated circuits, it is
