Selective capacitor disconnection for passive harmonic filters
Capacitors must be easily accessible in order for customers or equipment manufacturers to implement a suitable switching device. When capacitors are connected, this can lead to extremely high starting currents. And once they have been connected and disconnected a number of times, switching contacts tend to become worn or welded.
Capacitor
If the capacitor is connected to the battery, then the voltage stays constant. It stays equal to the battery voltage. The battery is a charge pump. It can pump charge from one plate to the other to maintain a constant potential difference. If the battery is disconnected from the capacitor, the charge on the plates stays constant.
Capacitor charged then disconnected
FAQ: Capacitor charged then disconnected 1. What happens to a capacitor when it is charged and then disconnected? When a capacitor is charged and then disconnected, it retains the stored electrical energy in the form of an electric field between its two plates.
