For most power system switching applications, once the voltage is decayed below 10% it is typically safe for reclosing, switching etc. The most common method of power capacitor discharge is to permanently connect resistors across the terminals.
When does a capacitor discharge?
It will spring back to its relaxed state whenever it is released from whatever is keeping it stretched. More specifically, a capacitor discharges whenever the voltage in the circuit the capacitor is part of has a smaller magnitude than the voltage stored on the capacitor.
How do you discharge a capacitor?
You can discharge a capacitor using a tool specifically designed for the purpose, like a discharge resistor. This tool helps to safely release the stored electrical charge in the capacitor without causing damage. If you don’t have a discharge tool, you can use a well-insulated screwdriver with a metal shaft.
