Introduction of bridge tester medium and low voltage cable fault detector (bridge tester) At present, a large number of cable fault detectors, such as a series of cable fault detectors, generally include: fixed point tester, path tester, pulse capacitor, etc. Its application range is: testing high-voltage cables, low-voltage cables, street light cables, buried line low-resistance faults, high-resistance flashover faults, high-resistance leakage faults, disconnection faults, grounding faults, etc. The test principle of the bridge tester cable fault detector: the low-voltage pulse method is used to test the full length of the cable, the transmission speed, the disconnection fault, and the low resistance fault, and the test distance can reach 13KM.
The high voltage pulse method is used to test for high resistance faults. Perform fault location using acoustic and magnetic synchronization principles. Use electromagnetic waves to find cable paths.
In conclusion, the traditional configuration is a complete configuration that can perform most of the cable fault testing functions. Advantages: Because the cable fault detector has complete functions and functions, the user can solve most cable faults, the cost is low, the scope of application is wide, the instrument popularization rate is high, and the use and maintenance are convenient. Disadvantages: Due to the rough detection of faults, the precise point of faults, and the cable fault detector in one set of instruments.
Therefore, there are high requirements for the technical level of personnel. Users are usually required to receive technical training from the manufacturer prior to use. Also, the rough test method is the flash test method.
Therefore, for joint faults with long creepage distances, there is no fault point waveform during rough testing since the fault point cannot flash. Bridge Tester 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.
