HM-A30 cable fault locator

Product features

HM-A30 High Voltage Moveable Cable Fault Locator adopt TDR teory, which 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.

The cable fault locator test system can test the high resistance flashover fault of the cable, grounding of high low resistance, short circuit and cable wire-broken and poor contact fault etc, if equipped with a sound detection method fix point meter, can accurately determine the precise location point of failure, especially suitable for testing various types, different rating voltage power cables and communication cables.

Advanced features 
* In China,Under Ground Cable Fault Locator 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 of Under Ground Cable Fault Locator 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.
