FDGE9 Discharge Coil |
| Applications |
FDGE9 discharge coil is suitable for electric power system with rated frequency of 50Hz or 60Hz and rated voltage of 10kv or under. Parallel connected with high voltage capacitor bank. When capacitor bank break with system, FDGE8 can decrease the left voltage of the capacitor bank to be under safe voltage within 5 seconds. Under normal operation, secondary winding can indicate the voltage. If user has special demands, it can also load the left voltage winding to have the function of relay protection.

| Structure and Feature |
| The series discharge coil is post type. Its hemetically sealed by epoxy resin, with design advantages of anti-pollution, anti-damp, easy to be installed is also suitable fortropic area and free from special maintenance except periodically surface clean. Secondary outlet teminal is equipped with connection teminal box. Upside and profile of the box have a hole respectively. The two holes together with outlet terminal are for leading out.There have earth bolt at the bottom of the PT. Six holes at the bottom of the PT are suitable for mounting. |
