FDGE8 Discharge Coil
Applications
FDGE8 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.
Accord with DL/T 653-1998 "Discharge Coil Order Technical Condition for Voltage Parallel Capacitor"
