Product Details

Cable Fault Comprehensive Tester can test various types of faults in copper and aluminum core power cables and local telephone cables of different voltage levels. The wave propagation speeds of four common power cables, including oil-impregnated paper cables, cross-linked ethylene cables, non-dripping cables, and plastic cables, are pre-set in the instrument. The wave propagation speed of some special cables can be temporarily pre-set on site using the keyboard. The cable length and fault distance do not require manual conversion; the instrument automatically converts and displays the fault distance.

• Can test open circuit and low resistance faults of various types of cables, as well as high resistance flashover faults and high resistance leakage faults of power cables.

• For simple open circuit and short circuit fault waveforms, the instrument can automatically analyze and automatically mark the fault point with dual cursors, and display the fault distance without manual intervention.

• One screen can simultaneously display two waveforms (fault waveform and overall waveform), bringing great convenience to users in waveform analysis.

• The waveform displayed on the screen can be arbitrarily expanded, compressed, shifted left, and shifted right.  

• The instrument is equipped with a panel-type high-speed micro printer, which can print test waveforms, data, and other related content at any time.

• The operation process of the instrument is prompted by expert Chinese characters, so even first-time users can operate it with ease.

• The instrument has built-in operation instructions that can be called up and displayed for learning at any time.

• It can simultaneously display two test waveforms or compare and display one test waveform with a standard waveform on the same screen.

• It can store nearly a thousand test waveforms on site, which are not afraid of power failure and can be permanently saved in the instrument.

• The instrument software is fully standardized in design, and the instrument software can be copied to any PC.

• It has the functions of measuring speed (propagation speed of electric waves in cables) and measuring time (return time of fault point echo).

• The instrument has a variety of standard test waveforms stored in memory, which users can call up for learning and reference at any time.

• It can directly adopt multiple test methods without adjusting the instrument itself.

    Cable Fault Comprehensive Tester can use modern classic DC high voltage flashover method, impulse high voltage inductance sampling method, impulse high voltage current sampling method, low voltage pulse method, and other test methods to perform fault analysis, detection, and pinpointing of various types of faults such as short circuit faults, open circuit faults, high resistance flashover faults, and high resistance leakage faults in various types of power cables. At the same time, it can also perform preliminary testing of short circuit and open circuit faults in control cables, local telephone cables, and coaxial communication cables, and can also verify the total length of cables.
