How to Discharge a Capacitor
Discharging capacitors makes them a lot safer and more reliable to work with. Resetting Capacitor Charge Discharging capacitors also helps to reset them for use. As we have said earlier, the capacitor works with two conductors separated by an insulator. While
Everything You Need To Know About Safety Capacitor
Safety capacitors (both the type X and type Y) work by supplying an instantaneous high-capacity current to the device that is connected to the power source. In most cases, the capacitors are used in combination with the overvoltage protection devices or surge protectors whose function is to detect any surge of current in a circuit.

How to Select the Right Safety Capacitors for Power Applications
X/Y Capacitors: Some safety capacitors handily combine classes, for example, X1/Y2. This simply means that the capacitor can be used as an X1 capacitor in an across-the-line application or as a Y2 capacitor in the line-to-ground portion of the circuit.
