DKSC series of earthing transformers are mainly used in the isolated neutral three-phase power system and the products supply artificial neutral point for the network system. The neutral point can put to earth directly or through electric reactor and extinction coil. When the single-phase ground fault occurs, the failure current will be released to the ground through the grounding transformers and extinction coil rapidly, which prevent the short circuiting are from burning continously and protect the other equipments in network system again damage to avoid the accident expanding further.
