Power Factor:
Power factor is a calculation representing the relationship of "real" power (kw)
which performs useful work in turning a motor, to "apparent" power (kva) which
magnetizes motor and transformer coils. Motor loads frequently adversely affect
the power factor of a circuit, usually from oversized or lightly loaded motors.
Certain other types of loads can reduce power factor.
A low power factor also reduces the capacity of circuit conductors to deliver "real"
power and can increase wiring costs as well as electric demand on the utility
system. FPL reserves the right to adjust meter reading kw for billing where power
factor is less than 85%.
Capacitors are sometimes connected on the load side of a motor controller to
improve the power factor of the circuit. When this is done, the total kvar
connected should not exceed the value required to raise the power factor of the
motor to unity when it is running unloaded.
