POWER FACTOR =R\Z.(RESISTANCE divided by IMPEDANCE)

POWER FACTOR=KW\KVA(KILOWATTS divided by KILOVOLTAMPS,OR APPARENT POWER)

POWER FACTOR= cos

TOTAL POWER when three phase Pt=Ixvxpfx1.732

PF = KW/KVA 1000kw/1200kva = 0.83

Dear

its nothing but how much real power and reactive power the device is drawing.

if energy meter with display of kW and kVA is available for individual equipment or plant incoming.

PF = kW/KVA

If you want to improve the power factor, the required kVAR calculation is

Required kVAR for compensation = kW (TanQ1 - TanQ2)

Q1 (pi1) = Present power factor (ex = 0.6)

Q2 (pi2) = Required power factor (ex = 0.99).

This is to improve the power factor from 0.6 to 0.99.
