Abstract
In a series capacitor transmission system the protective bypass device has a force firing arrangement responsive to an applied signal for causing the series capacitor bank to be bypassed rapidly, such as within three cycles, for reducing subsynchronous oscillation effects on generating equipment connected with the transmission system. A capacitive potential device supplies power to energize a firing control circuit with a pulse transformer placing high frequency or pulse voltage across the protective device for rapid bypassing. The bypass device may be a protective spark gap as is normally present for protection of the capacitor bank against overvoltages.
