Zero-sequence and phase-sequence integrated electronic voltage sensors ensure accurate voltage detection, optimized electrical stability, and enhanced fault monitoring. Designed for industrial and grid applications, they provide superior insulation, extended durability, and precise sequence measurement.
Product Overview
The Zero-sequence and Phase-sequence Integrated Electronic Voltage Sensor is an advanced high-voltage power protection sensor specifically designed for zero-sequence protection in power systems. The sensor directly outputs small voltage signals without the need for secondary PT (Potential Transformer) conversion, simplifying the system structure, reducing sources of error, and meeting the demands of “digitalization, intelligentization, and networking” in power systems. It is widely used in gas-insulated ring main units and other power facilities for intelligent measurement and monitoring of zero-sequence and phase-sequence voltages.
Features
- Small Signal Output: Directly outputs small voltage signals, simplifying system design, reducing sources of error, and improving accuracy.
- Coreless Design: Does not contain a core or only uses a small lightweight core, preventing core saturation, providing a wide frequency response range and large measurement range.
- High Safety: No overcurrent or ferromagnetic resonance occurs during secondary short circuits, reducing the risk of system failure and ensuring the safety of both equipment and personnel.
- High Reliability: Able to operate stably during system failure, ensuring reliable operation of protective devices.
- Compact and Powerful Functionality: With multiple functions, it can output either zero-sequence voltage or phase-sequence voltage. Its compact size, lightweight, high energy efficiency, and reduced ferromagnetic pollution make it suitable for modern systems.
- Flexible Configuration: Can output either zero-sequence voltage or phase-sequence voltage, and zero-sequence voltage can be synthesized through control devices to adapt to different application scenarios.
