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. Computer …
