AI Customer ServiceThe capacitor power necessary for this compensation is calculated as follows: Qc = P · (tan φ1 – tan φ2) Compensation reduces the transmitted apparent power S (see Figure 3). Ohmic transmission losses decrease by the square of the currents.
The k factor is read from a table 1 – Multipliers to determine capacitor kilovars required for power factor correction (see below) and multiplied by the effective power. The result is the required capacitive power. For an increase in the power factor from cosφ = 0.75 to cosφ = 0.95, from the table 1 we find a factor k = 0.55:
