Multiple Pulse Cable Fault Tester

I. Overview:

The XFH-8637 Cable Fault Tester is designed for detecting short circuits, open circuits, low-resistance ground faults, high-resistance leakage, and high-resistance flashover faults in various cables below 35kV voltage levels.

The XFH-8637 Cable Fault Tester is developed based on the advanced secondary pulse method cable fault testing technology. In addition to all the advantages of the secondary pulse method cable fault tester, it introduces a significant feature: while performing high-voltage impulse discharges, the pulse generator continuously sends a set of eight cable fault testing pulses and a set of eight full-length cable testing pulses (totaling 16 pulses) with different delay times. Operators can select an easily analyzed cable fault reflection waveform from the eight groups of cable fault waveforms displayed on the screen. This eliminates the need for complex parameter settings and repeated high-voltage impulse discharges. This is because the eight groups of fault waveforms are obtained at the moment of triggering the pulse generator with high-voltage impulses at different time intervals. It also eliminates the cumbersome medium-voltage extension arc device, simplifies the testing process, and provides users with a more straightforward method for fault waveform judgment.

This instrument utilizes the most advanced internationally available technology."The 'Multiple Pulse Method' technology, an independently owned testing technology, and a multi-pulse generator with Chinese characteristics, endow the instrument with excellent cable fault waveform judgment capabilities and a simple and convenient operating system. This instrument boasts independent intellectual property rights and is the first domestically developed successfully in China."IndependentUniqueNo Chinese content provided."Pulse Testing Instrument for Cable Faults Using the 'Multiple Pulse Method'"

The advanced aspect of the multiple-pulse method lies in the fact that the fault waveforms obtained from on-site testing provide operators with more flexibility, eliminating the need for continuous adjustment of the test pulse delay time to achieve an ideal secondary pulse waveform.No need for cumbersome medium-pressure rolling arc equipment. Reduced technical and experience requirements for operators. Enhanced accuracy in identifying on-site malfunctions. Anyone can conveniently and accurately interpret waveforms, calibrate fault distances, achieving the goal of rapid and precise cable fault testing.

The overall technology of the XFH-8637 Cable Fault Tester is comparable to foreign counterparts, and its performance-to-price ratio is significantly superior to similar products domestically and internationally.

The XFH-8637 Cable Fault Tester features a large, true-color touch screen with clear waveform characteristics display. Thanks to the defined screen touch simulation buttons, the operation is extremely simple.
