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

Answer / rajesh
power factor is the cosine of the angle between voltage and
current. if voltage and current are in phase then power
factor is unity. however, in practice this not possible
since loads are not purely reistive.
cos phi = active power/apparent power

A graph drawn between voltage(V) and Current(I), a curve
will form due to loss between voltage and current. This is
called power factor.
This is also defind as the ratio between Apparent power to
Actual power.
Power Factor = KW / KVA.

Answer / r ksharma
It is defined as the ratio resistance to impedance.It is
either leading or lagging.
Is This Answer Correct ? | 2 Yes | 1 No |
Answer / suvajit
It is the ratio of the resistance(R) of the circuit to the
impedance(Z) of the same circuit.
Power factor=R/Z.

Is a contactor (or master relay) required between incoming lines and a VFD? The question goes to safety. If a contactor were used before the VFD and an e-stop engaged then the motor will coast to a stop (i.e. VFD loses power) instead of stopping much faster if the VFD braking fucntion were used. It would make more sense to keep power on the VFD.
