Product Description
This 12kv Discharge Coil of discharge coil is of outdoor epoxy resin casting full-sealed product. It is applicable to be used for the power system with AC frequency 50Hz and rated voltage 10kV and below. It is connected with high voltage parallel connection capacitor group.When capacitor group cuts off from the system, it can take only five second to reduce the resi-dual voltage of the capacitor group to safe voltage. When operating is normal. The secon-dary winding is used as voltage indicator. If users have special requirements, it can have relay protection action with residual voltage winding.
