Adopting a 10.4-inch industrial grade color touch screen and a menu style operation interface, it supports waveform scaling, storage, retrieval, and automatic distance detection functions, making it easy for non professionals to quickly get started.
Integrating 7 testing methods including low-voltage pulse method, impulse flashover method, and triple pulse method, covering various scenarios such as cable breakage, short circuit, and high resistance faults, with a testing accuracy of ± 1 meter and a maximum ranging range of 60 kilometers.
Powered by a built-in battery, it can work continuously for more than 4 hours without an external power source, meeting the needs of complex outdoor environments.
The acoustic magnetic digital synchronous fixed-point instrument combines the electromagnetic wave and sound wave time difference algorithm, and displays the real-time distance of the fault point (0.1-99.9 meters) through the digital screen, effectively eliminating environmental noise interference, with a fixed-point error of less than 0.1 meters.
Supports synchronous detection of sound and magnetic fields, equipped with multiple filtering modes including high pass, low-pass, and band-pass, suitable for different scenarios such as hard road surfaces and soft soil, greatly improving detection efficiency in complex environments.
Built in high-voltage protection mechanism to prevent equipment damage during impact flashover testing, and equipped with safety warning function to prohibit use in high gas and flammable environments, ensuring operational safety.
The path detection module can accurately determine the cable burial path and depth, and with the help of a fault locator, achieve a closed-loop process of "rough measurement path precise positioning", significantly reducing the time for fault diagnosis.
