Pole-type Current and Voltage Transformer (Sensor)

It is suitable for external mounting on ZW32 circuit breakers. This pole integrally integrates a zero-sequence voltage sensor and an electromagnetic current sensor (including phase sequence and zero sequence). While realizing the full functionality of measurement, metering and protection, it greatly improves the accuracy of line grounding judgment and boosts the upgrade of power supply stability and reliability.

Features

This pole is structurally designed in accordance with the technical requirements of primary and secondary integrated complete pole-mounted circuit breakers of the State Grid Corporation of China and China Southern Power Grid Co., Ltd., as well as the group standard T/CES 018-2018 Technical Specifications for AC Sensors in 10kV and 20kV Distribution Networks. It innovatively adopts an integrated design of combined sensor, insulating cylinder and lower outlet terminal, and is equipped with a standardized secondary wiring harness. While ensuring the compliance of sealing and insulation performance, it reduces assembly difficulty and improves assembly efficiency and quality. Comprehensively optimized in terms of performance and cost, it provides users with a cost-effective solution for upgrading and replacement.
