SERIES CAPACITOR SYSTEM WITH FORCEFIRING OF PROTECTIVE BYPASS DEVICEABSTRACT OF THE DISCLOSUREIn a series capacitor transmission system theprotective bypass device has a force firing arrangementresponsive to an applied signal for causing the seriescapacitor bank to be bypassed rapidly, such as within threecycles, for reducing subsynchronous oscillation effects ongenerating equipment connected with the transmission system.A capacitive potential device supplies power to energize afiring control circuit with a pulse transformer placing highfrequency or pulse voltage across the protective device forrapid bypassing. The bypass device may be a protectivespark gap as is normally present for protection of thecapacitor bank against overvoltages.
