Question: What are the methods for Shenzhen cable fault detection? Answer: During the construction and maintenance of the mechanical and electrical equipment installation project, there will be cable failures caused by various reasons. Therefore, it is necessary to have applicable theories and methods to solve all kinds of faults. The question of this article: What methods are there for Shenzhen cable fault detection? Answer: During the construction and maintenance of the mechanical and electrical equipment installation project, there will be cable failures caused by various reasons. Therefore, it is necessary to have applicable theories and methods to solve all kinds of faults. This paper expounds the traditional detection methods. The fault point detection of cables generally has to go through three main steps: fault type diagnosis, fault point distance measurement, and precise point determination. .
The fault type diagnosis is mainly to determine the fault phase of the fault point of the cable, which is high-resistance grounding or low-resistance grounding, so that the tester can choose the appropriate detection method. The fault point distance measurement is also called pre-positioning. A test signal is applied to the faulty cable core wire or online measurement and analysis of the fault information are carried out to initially determine the distance of the fault and minimize the fault range to facilitate accurate point determination.
