AI Customer ServiceMETAL-ENCLOSED POWER CAPACITOR BANKS... NEPSI’s Medium Voltage Metal-enclosed Shunt Power Capacitor Banks are custom designed for application on industrial, commercial, and utility power systems that require medium voltage power factor correction. The capacitor banks are configurable as fixed or automatic controlled with 1 or more stages.
It is preferred to connect discharged capacitor banks to the network because the voltage difference will be equal to the voltage of the system or less. In contrast, if a charged capacitor bank is connected at the wrong time instant, there can be a voltage differential of up to two times the nominal system voltage [ 1 ].
The energy from the capacitor banks is discharged by driving the transformers into saturation after disconnection from the grid. To investigate this, simulations were conducted in PSCAD to identify the relationship between the size of the transformer, the size of discharge resistor and the time taken for the capacitor bank to discharge.
Capacitor bank can hold dangerous voltage after disconnecting from power system unless discharging devices are connected to the capacitor terminals.
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.
It has been shown that if the PSCAD simulations of the full-scale circuit are correct, discharge times under 0.2 s can be achieved depending on the transformer size and discharge resistor size chosen. From this paper, it was shown that this method of discharging capacitor banks is likely to achieve the results obtained from the initial simulations.
