Description

Description ：

This device has the functions of real - time monitoring and accurate early - warning. Through advanced sensor technology, it conducts all - round monitoring of the cable's operating status, including important parameters such as current, voltage, temperature, and partial discharge. Once an abnormal fluctuation in the parameters is detected, the system can quickly identify potential fault hazards and issue early - warning signals in a timely manner. This enables maintenance personnel to take corresponding measures before a fault occurs, avoiding power - outage accidents and effectively improving the reliability of power supply.In terms of fault positioning, the device uses a variety of advanced technical means, such as traveling wave ranging and impedance method. When a cable fault occurs, these technologies can quickly and accurately determine the location of the fault point with a very small margin of error. This greatly shortens the time for fault troubleshooting and repair, reducing the power - outage time and its impact on users.This device is widely used in urban distribution networks, industrial parks, commercial centers and other places, providing strong support for ensuring the safety and stability of power supply.
