In the power system, cable failure will not only affect the continuity of the power supply but also may cause equipment damage and safety accidents. Therefore, power engineers need to master a complete set of emergency handling processes to quickly restore the power supply and ensure the safety of the system and personnel. The following is a detailed emergency handling process that aims to provide effective and practical guidance for power engineers.

In power systems, cable faults significantly impact stability and safety. Understanding cable fault types and mastering detection methods are critical for ensuring reliable cable operations. Below is an overview of common cable fault types and detailed detection methods with key operational tips.

In testing cable faults it is necessary to determine the underground cable path, otherwise we cannot locate the point directly above the cable and within the distance of the rough fault. When relocating and remodeling cables, we need to know the underground path of the cable, otherwise we can't work.

Recently, our company was delighted to receive good news, successfully securing orders for a total of three devices from new clients in Chile and Croatia. Among these, two are high-performance relay protection testers, and one is an advanced cable fault locator. This not only demonstrates our company’s competitiveness in the international market but also highlights the strength of our factory and our exceptional services.

When cable faults occur, obstacles must be eliminated quickly to restore communications as soon as possible, first of all, the nature of the obstacle should be judged and then select the appropriate instrument to determine the precise location of the obstacle in time to carry out cable line repair work, the determination of the precise location of the obstacle is generally used to determine the precise location of the obstacle to the instrument cable fault tester.

Cables are susceptible to faults caused by insulation aging, insulation moisture, cable overheating, mechanical damage, sheath corrosion, overvoltage, material defects, intermediate joints and terminal head design and manufacturing process problems during normal operation and maintenance operations.

Once a fault occurs, it usually takes a lot of manpower and material resources to dig the cable out of the ground for troubleshooting. This type of troubleshooting method is most likely to cause problems such as low troubleshooting efficiency, long search time, and low test accuracy. This article will combine the work experience in recent years to explore the types of signal cable faults, the main causes, and the methods and techniques for finding cable faults using cable fault testers.

Discover the efficient cable fault testing system: Based on the principles of "thumping flash," it quickly locates cable issues and is widely used across industries to ensure electrical safety.
