Answer / sujit288
PF is the ratio between true power & apparent power./PF is
the angle between voltage & current.
PF in HT side PF=KWH/KVAH

Answer / rajesh singh
The angle between crrent& voltage is called power
factor.Formula- p.f=p/v.I
| Is This Answer Correct ? | 28 Yes | 17 No |
Answer / hari
The cosine angle between voltage and current vectors is called a power factor.
power factor = active power/apparent power.
Note:The power factor is depending up on reactive power. so it is not need on(special) HT side.

Answer / rajkumar
Power factor is an angle between the waveform of voltage
and current P.F=cos*
P.F=KW/KVA
| Is This Answer Correct ? | 12 Yes | 9 No |
Answer / shivakumar k
The phase angle between current and voltage.
The ratio between true power and apparent power.
cos*=kWh/kvah
| Is This Answer Correct ? | 1 Yes | 1 No |
It is ratio of True Real Power to Apparent power.
Cos phi = KW/KVA = R/Z = True Real Active Power / Apparent power
KW = sq root of 3 x V x i x Cos Phi
hence cos phi = KW / ( sq root of 3 x V x I)
