The JDZ10-12V12G is a 12kV indoor single-phase voltage transformer featuring epoxy resin casting and double-pole insulated fully enclosed construction. It is designed for indoor use to measure voltage, electric energy, and provide protective relaying in electrical systems operating at 50Hz or 60Hz with equipment voltages up to 12kV.
This transformer offers high reliability, a low magnetism core, and a large creepage distance on the external insulation to resist pollution. It is maintenance-free and supports a load power factor of cosΦ=0.8 (lagging). The product complies with IEC 60044-2 and IEC 61869-1 & 3 technical standards.
