HM-A50 Cable Fault Locator Operation Video
Product Overview
Overview
To meet the rapid development demands of the power industry, Goldhome has developed the HM-A50, an integrated device combining traditional standalone cable fault pre-locators, high-voltage power supplies, multi-pulse generators, path transmitters, and insulation resistance testers.
This system is suitable for cable fault distance rough measurement, path tracing, and precise fault location. The testing software can identify and capture complete waveforms, automatically determining the cable fault distance.
Key Features & Advantages
- The system features an integrated design for easy portability and flexibility.
- Suitable for testing various main insulation faults and outer sheath faults in cables ranging from 380V to 220kV.
- Integrates multiple testing functions, including fault testing, high-voltage power supply, insulation resistance testing, and cable route tracing.
- The fault testing unit employs an industrial control embedded computer platform running the Linux operating system.
- The high-frequency high-voltage power supply unit employs a touchscreen control system, enabling user-friendly operation with a clear and intuitive display.
- The insulation resistance test unit features a digital design with an LCD screen displaying real-time instrument status and test results.
- The cable path test LCD screen synchronously displays signal frequency and strength from both transmitter and receiver.
- The system includes a 25-meter test cable for convenient cable fault location in long-distance, short-distance, and complex environments.
Functions
1.Cable fault re-locator unit
Adopt 12.1in big screen, knob mouse operation, highlight LCD display, suitable for outdoor use in the sun. Lithium power supply for cable fault distance, very convenient for field test.
Adopt latest integrated communication technology, signal acquisition is stable.The host can select 6 frequency automatically , as low as 6.25MHz, as high as 200MHz. The adaptive pulse width can meet the test requirements of cables in different length, reduce the prediction error and improve the test accuracy.
2.High voltage power supply unit
Integrated design, built-in capacitance.
Touch screen man-machine interaction, easy to set up and operate, instrument status display intuitive and convenient.
With functions of voltage regulation, automatic voltage stabilization and automatic protection.
The output high voltage has the function of single pulse and continuous pulse, which can cooperate with fault tester and fixed point instrument to find fault points respectively
The output high voltage has DC output, which can work with the ball gap.
The software controls the vacuum impact spark discharge, adaptive discharge and pulse cycle.
With emergency stop key, automatic discharge function, emergency stop or stop automatic buck discharge, safe and reliable.
The continuous working time no less than 6 hours, which can meet the longest working time of cable failure test.
