The JDZ10-12C1 is a 12kV indoor single-phase voltage transformer featuring epoxy resin casting and double-pole insulated fully enclosed construction. It is designed for indoor applications to measure voltage, electric energy, and provide protective relaying in electrical systems operating at 50Hz or 60Hz with equipment voltages up to 12kV.
This product boasts high reliability, a low magnetism core, and a large creepage distance on the external insulation, enhancing its resistance to pollution. Maintenance-free in operation, it supports a load power factor of cosΦ=0.8 (lagging) and complies with IEC 60044-2 and IEC 61869-1 & 3 technical standards.
