Thus the number of capacitors is identical to the number of steps: six capacitors controlled by six steps. However, compensation banks with unequal steps, for example 50 kvar and 25 kvar (see Figure 1), enable compensation in ''fine-stepping'' mode.Smaller units up to 150 kvar approximately have combinations of different-sized capacitors for economic reasons.

KVAR (kilovolt-amperes reactive) is a unit of measurement for reactive power in an electrical circuit. It represents the magnitude of the reactive power, which is the power that does not perform useful work but is required to maintain the voltage levels in an AC circuit. How much does a 25 KVAR capacitor weigh?
Enter the reactive power in kVAR, supply frequency and voltage. Then choose which unit you need to calculate the capacitance value (mF or μF or F). Then press the calculate button to the kVAR to Capacitor value. kVAR is the SI unit of reactive power and Farad is the SI unit of Capacitor.
A 25 KVAR capacitor is typically used for power factor correction in electrical systems. It helps reduce the reactive power demand, improve the power factor, and increase the overall efficiency of the electrical system. What is the price of a 2 kVAR capacitor?
For the system shown in the picture above, capacitors are rated at 400kVAR at 7.2kV. Individual capacitors are connected line-neutral. The System line-line voltage is 12,470V. The net rating of the bank is 400*3=1,200kVAR. To calculate the full load current, enter 1,200kVAR as rating and voltage as 12,470V in the three phase calculator above.
Multiply this number with the existing active power in kW. You can find the real power by multiplying the voltage to the current and the existing lagging power factor i.e. P in Watts = Voltage in volts x Current in Amps x Cosθ1. This easy way, you will find the required value of capacitance in kVAR which is needed to get the desired power factor.
Thus the number of capacitors is identical to the number of steps: six capacitors controlled by six steps. However, compensation banks with unequal steps, for example 50 kvar and 25 kvar (see Figure 1), enable compensation in ''fine-stepping'' mode.Smaller units up to 150 kvar approximately have combinations of different-sized capacitors for economic reasons.

1 unit air-compressor ( 3 phase 415 VAC ) used an average of 90 kW with an existing power factor of 80%.The desired power factor is 95%. The factor value for this case is 0.421 to raise the power factor from 80% to 95% using table 1. 0.421 x 90 kW = 38 kVAR. So we need capacitor size 38 kVAR to get power factor 95% for 1 unit air-compressor 90 kW.
