How to detect cable fault detection The main method of cable fault test, then as a cable fault test, the most important thing is a detection requirement of cable fault, so what is a cable fault? It is not difficult to provide the status indication of power transmission and load bearing. In the fault analysis report of Dingsheng Power, it is not difficult to find that cable faults are generally divided into open circuit faults, short circuit faults, high resistance type faults and low resistance type faults. In terms of the probability of the application field of low-voltage cables, the probability of ground faults in low-voltage cable faults is much higher. On the contrary, most of high-voltage cables are high-resistance faults. Of course, we only refer to some after-sales data to get a probabilistic accounting Specifically, the characterization of cable faults requires the support of data, usually digital megohmmeters and multimeters. This time, we will share the basic detection methods of high and low voltage cable faults with a cable fault tester. At present, in the field of cable fault finding, the principle of fault cable detection is basically the same, the difference lies in the way of processing through this principle is different.“Low pressure pulse method”and“high pressure flashover”, In addition, the two-pulse cable fault tester and the multi-pulse cable fault tester have the same measurement principle, but in order to meet the needs of different users, the processing methods are different. The low-voltage pulse method refers to a principle method adopted in that the fault resistance of the faulty cable is relatively small. According to the application experience of Dingsheng Power, when the resistance is less than a certain ohm, the fault point can be located by the potential difference between the two points. Accurately locate and learn how to find low-voltage cable faults.
This is the main market value of Shenzhen Noyafa Electronic Technology Co., Ltd. as the main way to control the cable fault now.
