Contact UsHow to Discharge a Capacitor?
In high-voltage capacitors with a voltage of 10kV and below, a fuse is connected in series on each capacitive element, which serves as the internal short-circuit protection of the capacitor. Some capacitors are equipped with discharge resistors. When the capacitor is disconnected from the grid, it can be discharged through them.
