Accurate perception of line state

Convenient operation and maintenance

It is easy to install onsite, and it supports remote maintenance, module hot plug and replacement maintenance, which can significantly reduce dependence on automation technicians and the operation and maintenance workload.

It can provide remote metering, remote signal and remote control of lines, and it has also integrated various line state monitoring and edge computing functions such as differential protection, line loss measurement, on-site feeder automation, and wave recording playback.

The zero-sequence voltage, zero-sequence current, transient-state first half-wave and transient-state phase asymmetry method are adopted as comprehensive criteria, and complicated failures can be detected sensitively, such as high-resistance grounding and arc grounding in low-current grounding systems, which has high reliability.
