Abstract

Two 235 MVAR series capacitors have been successfully applied at the 500 kV Broadview substation of the Colstrip Transmission Project. The series capacitors have an overvoltage protection system based on metal oxide varistors. The system provides instantaneous bypass and reinsertion of the capacitors following external line section faults. The excellent performance of the equipment was demonstrated during staged fault tests performed in October 1985. The banks have been in successful operation since January 1986
