Product Introduction
The 24kV Solid-sealed Pole (Outdoor) complies with the technical specifications of State Grid’s primary and secondary fusion equipment, and is designed and manufactured in accordance with the requirements of T/CES 018-2018 Technical Conditions for 10kV and 20kV AC Sensors for Distribution Networks. It is an integrated AC sensor integrating phase-sequence voltage, zero-sequence voltage, phase-sequence current, zero-sequence current and voltage power-taking. The power-taking sensor, voltage, current and power-taking device are placed inside the product, which can directly form a primary and secondary fusion intelligent circuit breaker with the circuit breaker. It features simple installation, low power consumption, high accuracy and stable measurement.
