Smart Cable Fault Tester
DARUI Electric recommends for you
High Voltage Cable Fault Tester is a new generation of portable cable fault testing instrument carefully designed and manufactured by our company based on user requirements and field use considerations. It combines the fault testing part and path part of the original cable fault tester into one, reducing the size, adding DC power supply and USB communication interface. It can be used to detect various cable faults such as low resistance, high resistance, short circuit, open circuit, leakage faults, and flashover faults, and can accurately detect the fault point location, cable length, and burial path of underground cables. It adheres to our consistent principle of high technology, high precision, and high quality, bringing cable testing to a new level. It features accurate testing, high intelligence, wide adaptability, stable performance, and portability.
The instrument uses a Chinese character system, high-definition display, and user-friendly interface.
Features of the complete set of instruments:
The complete set combines fault testing and path detection into one, powered by lithium battery, lightweight host, easy to carry, and convenient for testing.
It adopts a new large-screen LCD display with high brightness and strong anti-interference capability.
Built-in DC power supply, convenient for on-site testing, field testing, and mine cable testing.
USB communication interface: currently only for professional production and technical personnel to debug and upgrade the host program.
Built-in micro printer, can print fax waveforms, providing convenient technical services for users to accurately analyze and guide waveforms on site.
The newly developed current sampler is a brand new sampling method, with simple wiring, intuitive waveform analysis, complete isolation from high voltage, and safety for the host and operators.
The key is the pinpointing instrument part, which borrows German technology, adopts advanced acoustic-magnetic synchronous reception technology, completely isolates external noise interference, and can quickly determine the cable path and accurate fault point location. It is another innovation in domestic similar pinpointing technology, providing strong guarantee for quickly and accurately locating cable faults and reducing power outage losses.
Dimensions: (length × width × height) 370×180×240mm.
This tester is used to roughly measure the actual underground distance of the fault point from one end of the cable, and also to measure the cable length and determine the propagation speed of electromagnetic waves in the cable.
