How to increase the size of the capacitor
Capacitor sizing for power factor correction
So we need capacitor size 38 kVAR to get power factor 95% for 1 unit air-compressor 90 kW. If working power (kW) or Present Power Factor are not known you can calculate from the following formulas to get the three basic pieces of information required to calculate kVAR.The best range for desired power factor is around 95% until 100%.
Effect of capacitor size on output voltage of a rectifier …
$begingroup$ You said in your question this: What I noticed also is that the bigger the capacitor size, the longer it took for the voltage to stabilise and, I gave the reason being that more current is …

POWER FACTOR CORRECTION – Applied Industrial Electricity
Since we know that the (uncorrected) reactive power is 119.998 VAR (inductive), we need to calculate the correct capacitor size to produce the same quantity of (capacitive) reactive power. Since this capacitor will be directly in parallel with the source (of known voltage), we''ll use the power formula which starts from voltage and reactance:

Determine Physical Size: Consider the physical size and form factor of the capacitor to ensure it fits within the available space in your circuit layout. By following these steps and considering these factors, you can determine the appropriate size of …
Can You Use a Larger Run Capacitor?
Run Capacitors. A run capacitor is an electrolytic capacitor with a relatively high capacitance value. A run capacitor is used to store electrical energy and to help maintain a constant voltage level n capacitors are designed to stay connected to a circuit for long periods of time and can handle large amounts of current. Run capacitors …
Basics of Capacitance
For example, if two parallel plates in the air had a capacitance of 120 pF and then the air was replaced with glass (the area and distance between the plates being unchanged), the capacitance would increase to 720 pF. …
