Product Overview

JSZY18-24RJ voltage transformer, is fully enclosed casting insulation structure, the primary winding, secondary winding and the annular core all coating in the epoxy resin casting, The product adds elbow type plug part, improving the filth and moisture resistance, is widely used indoor for measuring current, electric energy and protective relaying in the isolated neutral system with the frequency 50-60Hz and highest   voltage for equipment 24 kV.

Key Features     

• Strong Electromagnetic Interference Resistance：Featuring a unique shielding structure and winding design, it effectively withstands interference from complex external electromagnetic environments. Even in high-voltage substations with severe EMI, it accurately measures voltage and ensures the purity and accuracy of output signals.

• High-precision Composite Winding Design：The secondary side adopts high-precision composite windings, enabling simultaneous output of voltage signals with multiple accuracy classes. This meets the differentiated precision requirements of metering, measurement, protection, and other functional modules, avoids errors caused by signal conversion, and enhances overall system performance.
