High Voltage Transducer

This high voltage transducer is compatible with 50 ± 2.5 Hz power systems and can operate stably within a wide temperature range of −40 ℃ to +45 ℃. Whether under low-temperature conditions in harsh cold regions or in high-temperature, dry outdoor environments, it maintains stable and reliable performance, fully meeting the requirements of complex outdoor distribution applications.

Its core performance parameters are excellent. The rated zero-sequence voltage is (10 kV/√3)/(6.5 V/3), and the accuracy class reaches 1 (3P), enabling precise voltage signal acquisition and providing accurate data support for power system metering, monitoring, and fault protection. The rated load is 2 MΩ (AC), demonstrating strong load adaptability and stable matching with the operational requirements of distribution networks of different scales.

The insulation protection performance meets stringent standards, with insulation resistance greater than 1000 MΩ, a power-frequency withstand voltage of 42 kV/min, a lightning impulse withstand voltage of 75 kV, and partial discharge not exceeding 20 pC under 14.4 kV test conditions. These characteristics effectively resist overvoltage surges and partial discharge in the power grid, ensuring the insulation safety of both the equipment itself and the entire distribution system.

 

This high voltage transducer offers a wide range of applications and is primarily designed for use with ZW32-type pole-mounted high-voltage switches. It is widely used in urban 10 kV/20 kV distribution network upgrades, rural power grid renovations, industrial park distribution systems, new energy power plant grid-connection projects, and outdoor distribution applications in substations. It meets the voltage measurement, metering, and protection requirements of traditional distribution networks and aligns with the development trend toward primary and secondary integration in smart distribution networks, laying a solid technical foundation for the safe, efficient, and precise operation of power systems.
