Excel Calculator For Power Factor Correction


File Size: 126 Kb

Description
The permitted range of applied voltage at fundamental frequency, plus harmonic  components, together with manufacturing tolerances of actual capacitance (for a  declared nominal value) can result in a 50% increase above the calculated value of  current. Approximately 30% of this increase is due to the voltage increases, while a  further 15% is due to the range of manufacturing tolerances, so that  1.3 x 1.15 = 1.5
The capacitors will draws a leading current and partly or completely neutralize the lagging reactive
component of the load current. This This raises the power factor of the load.
Qc = Sqrt(3) (I)(V) SINφ
