The JDZ10-12Q(A/A1) voltage transformer is designed for indoor use with a rated primary voltage of 11kV and a rated secondary voltage of 0.11kV. It features epoxy resin casting with a fully enclosed structure to ensure reliable insulation and environmental protection. This transformer is suitable for accurate voltage measurement, electric energy metering, and protective relaying in single-phase or three-phase AC systems operating at 50Hz or 60Hz.
Offering multiple accuracy classes, including 0.2, 0.5, 1, and 6P, this transformer supports rated outputs ranging from 10 VA to 300 VA and thermal limiting currents up to 200 VA. It is designed with a rated insulation level of 12/28/75 kV, ensuring safe operation under electrical stresses typical in medium-voltage distribution networks.
