Cable fault tester - the cause of insulation aging deterioration and overvoltage Cable fault tester The intelligent cable fault tester management system produced by Shenzhen Noyafa is composed of test system, path signal generator, path signal receiver and positioning instrument. Cable fault test Tester - Reasons for Insulation Aging, Deterioration and Overvoltage Cable Fault Tester The cable fault intelligent tester management system produced by Shenzhen Noyafa consists of a test system, a path signal generator, a path signal receiver and a positioning instrument, which can complete the detection of cable faults. Testing and management of cable data are two tasks. Laptop for measurement control, data processing and cable data management. The fault test system cooperates with the notebook to measure the distance between the fault point and the test end at one end of the faulty cable, and can also be used to measure the length of the cable and the propagation speed of the radio wave in the cable; the path signal generator can generate 15KHZ, the maximum amplitude of 30V intermittent The sine wave signal is used to find and measure the cable path; the path signal receiver is used to receive the path signal, find the direction of the cable and estimate the buried depth of the cable; the locator is used to accurately locate the fault point.
Product nickname: cable fault detector, locator, path detector, cable fault path finder, cable fault tracer, portable cable fault location system, cable fault flash tester, cable fault locator, cable routing instrument Shenzhen Noyafa will introduce to you Reasons for insulation aging deterioration and overvoltage: Insulation aging deterioration (1) The slag or air gap inside the cable medium is freed and hydrolyzed under the action of the electric field. (2) The cable is overloaded or the cable is poorly ventilated, causing local overheating. (3) The insulation of the oil-impregnated paper insulated cable is lost.
(4) The power cable is used over time. Overvoltage Overvoltage can cause electrical breakdown of defective cable insulation, causing cable failure. The main reasons are: atmospheric overvoltage (such as lightning strike); internal overvoltage (such as operating overvoltage).
Shenzhen Noyafa is a source enterprise specializing in the production of power testing equipment. It is a manufacturer of insulation resistance testers, grounding resistance testers, cable fault testers, etc. The company has won unanimous praise from the market and customers with its good credit and high-quality products.
