Capacitor Discharge Graph: The capacitor discharge graph shows the exponential decay of voltage and current over time, eventually reaching zero. What is Discharging a Capacitor? Discharging a capacitor means releasing the stored electrical charge. Let’s look at an example of how a capacitor discharges.
Discharging a Capacitor Definition: Discharging a capacitor is defined as releasing the stored electrical charge within the capacitor. Circuit Setup: A charged capacitor is connected in series with a resistor, and the circuit is short-circuited by a switch to start discharging.
Easiest and most reliable way to ensure capacitor discharge is to permanently connect resistors across the capacitor terminals. As soon as power source is turned off, capacitor starts to discharge through the resistor. Discharge resistor can be externally connected or mounted inside the capacitor can.
Resistors are the preferred discharge device for capacitors though reactors and voltage transformers can also be used if faster discharge is necessary. By using resistor, the rate of discharge, resistor power dissipation can be controlled to a high degree by the designer.
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.
As soon as power source is turned off, capacitor starts to discharge through the resistor. Discharge resistor can be externally connected or mounted inside the capacitor can. Downside of using permanently connected external or internal resistor is steady state power loss.
