Summary
JDCF voltage transformer is a kind of outdoor fully-enclosed magnetic oil-paper insulated voltage & electricity measuring and relay protection device used in neutral point earthing power system with maximum voltage of 126kV and rated frequency of 50Hz or 60Hz.
JDCF has reliable design and low magnetic flux, able to avoid resonance overvoltage. Secondary windings separate measuring and protection. The measuring precision can reach Level 0.2, meeting different user requirements and high precision measuring requirements put forward by power departments.
JDCF has metal expander with stainless steel shell and the sealing adopts imported cushion. The body adopts advanced vacuum drying and vacuum oil treatment technique, featuring small dielectric loss and low partial discharging volume and enabling e the product run reliably and safely.
