What are the common difficulties in cable fault detection? 1. The cause of the cable fault is not clear. Through the detection of the faulty cable, and the data indicators of the cable are not abnormal, it is impossible to judge the type of cable fault, and even the cable is not closed. What are the common difficulties in fault detection? 1. The cause of the cable fault is not clear. Through the detection of the faulty cable, and the data indicators of the cable are not abnormal, it is impossible to judge the type of cable fault, and there is no suitable method. To detect the fault point of the cable. 2. The resistance of the cable is unstable. Because the position of the fault point of the cable is wet or there is water accumulation, the resistance of the detection cable fluctuates up and down, which affects the judgment of the cause of the cable fault. As a result, the progress of the detection work is delayed.
3. The surrounding environment is finally the interference of surrounding sounds. We all know that when the cable fault detector locates the fault point of the cable, the signal sound of the fault point is relatively weak, and a quiet environment is needed to monitor it. If the surrounding environment is too noisy , which will affect the signal snooping at the fault point. 4. Large cable length At present, the detection method of most cable faults is generally to collect the pulse current on the ground wire for analysis, but because the cable line is generally long, the attenuation of the partial discharge signal in the cable is too fast, and the signal detection is difficult. Shenzhen Noyafa Electronic Technology Co., Ltd. is a high-tech enterprise engaged in scientific research, production and sales, and provides technical services for cable fault detection.
At present, a variety of high-voltage test equipment and testing instruments have been widely used in the industry. At the same time, our company provides technical services such as cable fault detection and substation testing and testing to users across the country. The core engineer responsible for providing technical services has 20 years of on-site testing. Experience, can provide solutions according to different types of cables and site environment.
