The acceleration of industrialization and urbanization, as well as the electrification transformation of electric vehicle charging network, have substantially promoted a significant rise in power consumption, which also allows a variety of high-voltage cables power cables, the use of which increases year by year, the cable as a long-distance, high-capacity transmission of core equipment, is to meet the needs of various towns and industrial zones of electricity demand for the important outdoor facilities.

The unintentional damage of external construction and the erosion of the natural environment have made cable failures indefensible.Once the fault occurs, the traditional way of investigation is like looking for needles in the sea, which not only consumes a lot of manpower and material resources, but also leads to long power outage time, which brings great impact on production and life.And based on the complexity of the operating environment of the power cable, making the traditional "repair after the fact" mode is difficult to meet the safety requirements.

Now, Shenzhen Dingxin Intelligent Technology Co., Ltd. launched the cable online monitoring and early warning ranging system DX-WPS100-GZ02, it is to deal with this complex phenomenon and the exclusive technology program.The system supports traveling wave fault ranging technology, and builds an all-round perception network by deploying high-precision sensors in the key nodes of the cable.High-speed acquisition of instantaneous transient current signals through sensing acquisition device, in addition to real-time monitoring of the operating status of each cable, cable circuit routing for cable main insulation faults, but also specific judgment of the type of faults such as sexual grounding faults or intermittent grounding.

In addition, the background of the system is installed in the main station, configured with a primary system diagram to realize the functions of fault early warning, line selection and distance measurement. Once the parameters are monitored abnormally, the system immediately starts the intelligent analysis procedure, using advanced algorithmic models to deeply mine and analyze the data to determine the type and location of the fault.

Such power cable online monitoring and fault early warning ranging system, is not like the cable installed fully automatic "intelligent medical examination instrument"?Not only can the reliable detection type and indirect type fault problems, in order to realize the full transparency of each cable operation status, fully improve the field inspection to eliminate the efficiency of the fault hidden danger.
