Capacitor bank discharge methods – Voltage Disturbance

In automatic power factor [PF] correction capacitor banks, steps are typically only reenergized after voltage is reduced to less than 10% of the rated voltage. Resistors are the preferred discharge device for capacitors though reactors and voltage transformers can also be used if faster discharge is necessary.

Discharging a capacitor automatically | All About Circuits

When the capacitor voltage rises to about 6.2 volts, the SCR will trigger "on". That will dump the charge in the capacitor. The 15 ohm resistor limits the dump rate so the current will not melt the SCR. When the dump current drops below the hold current, the SCR will turn off and the capacitor will resume charging.

6 FAQs about [Capacitor automatic discharging device]

Which discharge device should be used for capacitors?

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.

How does a capacitor discharge?

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.

How do I control the discharge time of a decoupling capacitor?

The discharge time for each decoupling capacitor can be controlled using a series resistance to set the RC time constant. This enables the sequencer to turn off each POL after a known time delay following deactivation of the previous converter in the sequence.

Can a power capacitor be discharged?

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.

How long does it take to discharge a capacitor?

Traditional discharge resistors may take up to a minute for discharging capacitors at LV and up to 5 minutes at MV. For many applications requiring frequent switching, this time unacceptably long and another faster method would be preferred. Capacitors can be rapidly discharged if reactors are connected across the terminals.

What happens when a capacitor is disconnected from a power source?

When capacitor is disconnected from power source, an auxiliary relay connects capacitor terminals to resistor ‘r’ dissipating the charge across the resistor. See figure 3. Resistor ‘R’ is the built-in discharge resistance of the capacitors which is typically of high ohmic value.
