1) A rule of thumb has been developed over the years to help simplify this process. To select the correct capacitance value, start with 30 to 50μF/kW and adjust the value as required, while measuring motor performance. We also can use this basic formula to calculate capacitor sizing : 2) Determine the voltage rating for capacitor.

In order to adjust capacitance, a variable capacitor modifies the surface area of its overlapping plates. A variable capacitor, sometimes referred to as a tuning capacitor, is a kind of capacitor in which the capacitance can be mechanically or electrically altered on a regular basis.
One can limit the accuracy of a variable capacitor by understanding the physics of capacitors. A variable capacitor's error is typically proportional to the difference between its rated capacitance and physical size. Reducing the rated capacitance or making the object larger physically will lessen this.
Let’s explore the key factors that influence capacitor sizing decisions. The voltage rating of a capacitor determines the maximum voltage it can withstand without experiencing failure. When sizing a capacitor, always choose one with a voltage rating higher than the maximum voltage in your circuit to prevent breakdown and damage.
For P.F Correction The following power factor correction chart can be used to easily find the right size of capacitor bank for desired power factor improvement. For example, if you need to improve the existing power factor from 0.6 to 0.98, just look at the multiplier for both figures in the table which is 1.030.
