Power Factor Correction

Detuned Capacitor Banks are automatic capacitor banks made of several capacitor steps controlled by a power factor (PF) controller. They are able to adjust PF to any value between 0.8 lagging and unity. When the PF differs from the target setting for more than 1 second, the capacitor switching modules switch stages as needed to bring the PF as close as possible to

Why is resistor in parallel with capacitor needed in capacitor bank?

The resistors across the capacitors (especially R1/C1 because they are at high voltage) are there to discharge the capacitors when the device is unplugged, so that if someone touches the output they won''t get shocked. Because the capacitors are there only for smoothing, and not to allow the device to function for a while after power is removed, having the

Pre-insertion Resistors in High Voltage Capacitor Bank Switching

Abstract: The switching of high-voltage capacitor banks for reactive-power or voltage support can produce significant transients. It is well understood that reactors, pre-insertion resistors, pre-insertion inductors, and synchronous switching can mitigate the transients. Circuit inductance can limit peak currents but resistance damps the oscillations most effectively.
