How to Safely Discharge a Capacitor?
The best way to select a proper resistor is to use this formula: P = V²/R, where P is the power in watts, V is the voltage across the resistor, and R is the resistance in ohms.. For example, let''s say you''re discharging a capacitor with a voltage of 25V. If you wanted to use a 100ohm resistor, then you would need a power rating of at least 0.25W (25V/100ohms = 0.25).
Methods of Reactive Power Compensation
Capacitor Banks: In this method, a bank of capacitors forms a connection across the load. As we know that the capacitor takes the leading reactive power, thus this causes the decrease in power taken from the source. This resultantly improves the value of the power factor of the system. This is further classified as series and shunt compensation.
