Product Overview

JSZV18-24RJ 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   

• Wide Voltage Range Adaptability：The JSZV18-24RJ voltage transformer can adapt to significant voltage fluctuations based on the rated 24kV. It not only ensures normal operating voltage monitoring but also stably outputs accurate signals during transient voltage fluctuations or system voltage regulation, safeguarding the normal operation of measurement and protection systems.

• Fast Response Characteristics：With high-speed voltage signal response capability, it captures voltage changes in an extremely short time and converts them into secondary-side signals. When sudden voltage surges or drops occur in the power system, it provides timely signals for relay protection devices to quickly cut off faulty circuits.

• Low Hysteresis Loss：Using special magnetic materials and optimized design, it achieves extremely low hysteresis loss, reducing energy loss during conversion, improving transformer efficiency, minimizing long-term operational heating, and enhancing equipment stability and service life.
