35kv Multiple Pulse Cable Fault Tester/Underground Cable Testing

1.Product Overview:
This cable fault tester is developed based on the application of the advanced secondary pulse cable fault tester.Besides having a second pulse method has all the advantages of the cable fault tester, also extends the characteristics, is an important impact on high voltage flashover at the same time, pulse generator for sending a group of eight different delay time cable fault testing pulse length and a set of eight cable testing pulse (a total of 16 test pulse).The operator can select one of the eight cable fault waveform from the screen to analyze the cable fault reflection waveform.Save the complicated parameter setting and repeated impact high pressure flashover time.Because these eight sets of fault waveform are obtained at different time intervals in the moment of the impact high voltage trigger generator.It can simplify the test method and provide the user with a more simplified method to judge the fault waveform.
The cable fault tester adopts currently the most advanced "multiple pulse method" testing technology, its have the best cable fault waveform judgment and the most simple and convenient operating system.
The advantage of multiple pulse method is : the test of fault waveform make the operator has more choices, no longer in order to obtain an ideal second pulse waveform and to adjust the delay time of pulse test in the test, to reduce the technique and experience requirements for operators.The accuracy of fault diagnosis was improved.Anyone can read the waveform easily and accurately, calibrate the fault distance, and achieve the purpose of fast and accurate test of cable fault.
The whole technology of this cable fault tester can be compared with similar products abroad, and its performance price is much better than that of domestic and foreign products.
This cable fault tester adopts the super - color touch screen, and the waveform features are clear.The operation is very simple by using a well-defined screen touch simulation button.2. Product functions and features:
