HM-A30 Cable fault test system

underground cable fault locator Used to test various faults of power cable, cable path and depth of cable buried.And the accurate test of railway airport signal control cable and street lamp cable fault.

◆The built-in field waveform and field physical wiring diagram are conducive to the field test comparison and daily study, and can automatically generate test reports and print.
◆The key precise pointing device part can directly show the distance of the tester from the fault point by digital, adopting the static noise technology

Product features

HM-A30 cable fault test system is to cater to industrial solutions of the electric power industry and the rapid development of the IT era, make limitations of the original cable fault tester with industrial control platform for embedded computer system, network services, the USB communication technology systematically, and greatly improve the function of the use of the instrument and the use value and convenient site environment operation.In particular, it provides a unique multi-solution service mode and management learning software for the increasing fault of buried cable.The whole system meets the general technical conditions of special test instruments for power equipment in the standard <<DL/T849.1 ~ DL/ t849.3-2004>> of the power industry of the People's Republic of China, and the production follows the license of manufacturing measuring instruments of the People's Republic of China.This equipment is qualified products used by National Power Grid and China Southern Power Grid.The test system are consists of three parts: the system host, fault locator and cable tracing which are used to test various faults of power cable, cable path and depth of cable buried.And the accurate test of railway airport signal control cable and street lamp cable fault.

another name:power cable fault locator,underground cable fault detector,underground cable fault detector,underground cable fault locator price,cable fault locator machine.

Advanced features 

◆In China, it is advanced to adopt the embedded computer platform system of industrial control, the operating platform of the full computer XP system, the integrated software test, and equipped with the cable fault test software

◆Domestic leading use 12.1in big screen, touch mouse operation, high screen display, suitable for outdoor sunlight, lithium power supply, convenient field test.Engineering aluminum alloy housing, shock and moisture resistance to achieve strong stability.

◆With the latest USB communication interface, the acquisition signal is stable. The host can automatically select five sampling frequencies of 6.25mhz and 100MHz at the minimum. The adaptive pulse width can meet the test requirements of cables of different lengths, reduce the rough test error and improve the test accuracy.

◆The software can compress and expand the waveform arbitrarily. Two waveforms which are closer to the standard are displayed randomly on the same screen for you to compare and analyze accurately. The movement of double cursors can be accurate to 0.15m to improve the test accuracy and reduce the error.

◆Host support host comes with WIFI receiver function, special 3 g software can realize remote real-time field testing technology service experts at any time, experts host remotely users, business technology equipped with mobile phone android version of the testing software, field test to users to provide timely, accurate waveform analysis and communication anytime and anywhere, make you easy work (optional).

◆The built-in field waveform and field physical wiring diagram are conducive to the field test comparison and daily study, and can automatically generate test reports and print.

◆The key precise pointing device part can directly show the distance of the tester from the fault point by digital, adopting the static noise technology, which is another innovation of the same kind of fixed point technology in China, providing a strong guarantee for the fast and accurate finding of cable fault and reducing the loss of power failure.

◆The four types of high-voltage discharge parts are available for users to choose. The domestic leading  28kg HM-350 hf HV power supply replaces 65kg test transformer and operation box, and the integrated high-frequency HV power supply high-voltage impact part with capacitance built-in HM-350 is widely applicable, truly comprehensive and portable, leading in China.
