Cable Fault Comprehensive Tester can test various types of copper and aluminum core power cables and local telephone cables of different voltage levels for various faults. The electromagnetic 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 propagation speed for some special cables can be temporarily set on-site using the keyboard. The cable length and fault distance do not require manual conversion; the instrument automatically calculates and displays the fault distance.
• Can test open circuit, low resistance faults of various cable types, 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 use dual cursors to mark the fault point, displaying the fault distance without manual intervention.
• One screen can simultaneously display two waveforms (fault waveform and full view waveform), providing great convenience for users to analyze waveforms.
• The waveform displayed on the screen can be arbitrarily expanded, compressed, shifted left, or shifted right.
• The instrument is equipped with a panel-mounted high-speed micro printer, which can print test waveforms, data, and other relevant content at any time.
• The operation process of the instrument is guided by expert Chinese prompts, making it easy to operate even for first-time users.
• The instrument has built-in operating instructions that can be accessed and displayed for learning at any time.
• It can display two test waveforms simultaneously or compare one test waveform with a standard waveform on the same screen.
• It can store nearly a thousand test waveforms on-site, which are not lost during power failure and can be permanently saved in the instrument.
• The instrument software is fully standardized in design, allowing the software to be copied to any PC.
• It has the functions of measuring speed (propagation speed of electromagnetic 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 access for learning and reference at any time.
• Multiple test methods can be directly used 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 for 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. It can also perform preliminary testing for short circuit and open circuit faults in control cables, local telephone cables, and coaxial communication cables, as well as verify the total length of cables.
