FDGE8 type discharge coilDetailed product description：

Overview
The FDGE8 discharge coil is suitable for power systems with a rated frequency of 50Hz or 60Hz and a rated voltage of 10kV and below. It is connected in parallel with a high-voltage parallel capacitor bank. When the capacitor bank is disconnected from the system, it can reduce the remaining voltage on the capacitor bank to a safe voltage within 5 seconds. During normal operation, the secondary winding can serve as a voltage indicator. If the user has special requirements, the residual voltage winding can also be included to provide relay protection.
The product complies with the technical specifications for ordering discharge coils for voltage parallel capacitors (DL/T 653-1998).
