The JDZ10-12 series, including JDZ10-12, JDZ10-12V, JDZF10-12, and JDZF10-12V, are 12kV indoor single-phase epoxy resin voltage transformers featuring epoxy resin casting and fully enclosed construction. They are designed for indoor applications to measure voltage, electric energy, and provide protective relaying in electrical systems operating at 50Hz or 60Hz.
These transformers support equipment voltages of 7.2kV or 12kV and are suitable for use in three-phase V connections. They offer high reliability, a load power factor of cosΦ=0.8 (lagging), and comply with IEC 60044-2 and IEC 61869-1 & 3 standards, ensuring stable and accurate performance in indoor medium-voltage systems.
