UHV-500 Cable Fault Location Detectorunder Wuhan UHV can help many power workers to carry out all kinds of power tests more conveniently. 

The solutions for cable faults mainly include the following aspects:

Fault location and diagnosis: Use professional cable fault testers, such as local voltage test, insulation resistance test, resistance test, oscilloscope test, etc., to accurately find out the fault point. For buried cables, equipment such as underground conductor fault measuring instrument and buried cable abnormal position indicator can be used to determine the fault location.

Repair or Replacement: Once the fault point has been identified, repair work can be carried out if it is due to external damage or insulation aging. Repair includes steps such as cleaning the fault point, reconnecting or repairing the insulation. If the cable is severely damaged or the cost of repair is too high, consideration should be given to replacing the cable with a new one.

Preventive measures: Strengthen the routine maintenance and inspection of cables, and conduct regular insulation resistance tests to monitor insulation performance. At the same time, attention should be paid to preventing external damage, such as mechanical collision, chemical corrosion, etc. This can be achieved by setting up protective measures and avoiding excessive stretching or pressure.

Optimization of design and installation: In design selection, installation and construction, the cable should be fully considered in terms of the use of the environment, operating conditions and other factors, to select the appropriate cable type and specifications, to ensure the quality of installation. For example, protective measures should be set up in easily damaged places, such as pipes and sheaths.

Strengthen training and education: improve the professional skills and knowledge of cable maintenance personnel, so that they can better recognize and deal with cable faults and reduce the occurrence of faults.

In summary, solving cable faults requires comprehensive consideration of fault location, repair, prevention and optimization of design and installation and other aspects. By taking scientific and effective measures, the occurrence of cable faults can be minimized and the stable operation of the power system can be guaranteed.
