Application

This type of discharge coil is single-phase, cast resin insulated used in doors or outdoors connected with high voltage parallel connection capacitor group. When the capacitor group is cut off from the system, it can take only five second to reduce the residual voltage of the capacitor group from  2Un to below 50V. When operating normal, the secondary winding is used as voltage indicator and the residual Winding is connected as split triangle. If the pole of capacitor partial breaks down, it would bring the zero sequence voltage to drive relay protection gear. The product is small, light, little  partial discharge energy and high resistance to over voltage. It is a new product for superseding the oil type discharge coil.
