The JDZX15-12 is a 12kV indoor single-phase voltage transformer designed for use in single-phase or three-phase AC circuits to measure electric capacity, voltage, and support protective relaying. It operates at a frequency of 50Hz or 60Hz and is suitable for systems with a rated voltage of 11kV.
This transformer features a fully enclosed epoxy resin casting structure, offering low magnetism density and a large creepage distance for enhanced external insulation. It is highly reliable, resistant to pollution and humidity, and designed to be maintenance-free. The product complies with IEC 60044-2 and IEC 61869-1 & 3 standards, supporting a load power factor of cosΦ=0.8 (lagging).
