As a product of its prime factors: 2*2*2*2*2*2*2*2 = 256 or as 2^8 = 256
Pf is the symbol for Power Factor.
PF of 175 = 5 x 5 x 7 or 52 x 71
when lagging Power Factor changes to leading PF, then the voltage across the circuit in which capacitor bank is connected, is increased.
The ratio of active power (real power) and apparent power is called power factor ( pf ). Power Factor ( pf ) = Active Power / Apparent Power = .................. ( kvar )
Power factor = cos (angle)PF=cos @
When voltage and current waveforms are out of synch the power factor is reduced. In a pure resistance load the PF is 1. When inductance and capacitance is involved the PF is from 0 to 1.
It depends on the power factor. If the PF = 1, then you need 75kVA. In general, kVA needed = 75kW/PF.
Watts are the product of amp x volts. 200 x 110 = 22000. The above is correct for a pure resistive load. With an inductive load the formula is Watts = Volts x Current x PF Where PF = Power factor which is between 0 and 1. For definition of Power Factor, search wikipedia.com
0.5 lead PF or Power Factor means that the signal is ahead of the input voltage by a factor of 90 degrees. The lagging PF means it falls behind the input signal. In sinusoidal signals 0.5 lead or lag will be the same.
Power factor measures the phase difference between voltage and current. If they are in phase the Power Factor is one. If the current and voltage are out of phase the power factor is between zero and one. You can describe the PF by saying the current lags the voltage with a PF = .8 or the voltage leads the current with a .8 PF.
KVA is the vector sum of real and reactive power; put differently, KVA at a specified power factor will tell you how many KW you have: KW = KVA * pf You must provide a power factor or power factor angle (if angle, replace pf with cos (pf) in above equation) or total reactive power to calculate.
