POwer Factor is a cos angle between Voltage and current.

Answer / paramesh

real power /Uperant power is called PF

Answer / saravanan.n

true power/apparent power

Answer / gautham

power factor is the Cosine of Angle between the Applied
VOltage and current. It directly depends on the Load. If
the load is Inductive then the PF is LAGGING.If the load is
resistive the PF is leading.Power Factor takes value from 0
to 1. Unity Power Factor is the Idealised condition, means
least power dissipated and high effeciency.

It can also be calculated from R/Z and KW/KVA ratings.

Answer / sudhakar

true power(kw)/apparent power(kva)

Answer / sree

ration of power utilised and power suppied

Answer / satish m

It is the ratio of the resistance to impedance.

PF= R/Z.
OR
It is cosine of phase angle between voltage & current.

It can be improved by connecting the capacitors in parallel
to the supply.

Answer / ibrahim

real powere/Apparent power
kw/kva
R/z

Answer / srinivasan

power factor=real power\apparent power

Answer / saravanan.n

the power factor of acircuit may be defined as:

(1)the ratio resistance and impedance = r/z

(2)the ratio = watts/voltampers=trepower/apparent
power=V x I x cosQ /V X I

(3)the cosine of the angle of lead or lag current from the
applied voltage

In case of HV test on medium voltage cables, BS is asking for 4 U0 where as IEC is asking for 3.5 U0. Can any one advise me how this 3.5 times or 4 times U0 is derived?
