1) On site, it can quickly detect the partial discharge status of high-voltage electrical equipment, especially for switchgear. It is easy to use, small in size, light in weight, and easy to carry.
2) The design circuit of the partial discharge detection sensor utilizes advanced RF signal processing, high-frequency signal processing, and weak signal processing technologies, and adopts high-precision AD conversion and high-speed digital signal processing chips for digital signal processing, which has good anti-interference performance and measurement accuracy.
3) Combining ultrasonic waves, transient ground waves, contact ultrasonic waves, and high-frequency multiple methods to detect partial discharge signals.
4) Built in non-contact airborne acoustic sensor TEV sensor.
5) Having multiple windows such as waveform chart, phase chart, bar chart, and four element chart to analyze partial discharge test data.
6) Supports data storage and viewing functions, and can directly export data through SD card or USB.
7) Support multi-level threshold settings for attention and alarm, providing intuitive prompts for problems through different amplitude colors.
8) Powered by high-capacity lithium batteries, it can work continuously for more than 10 hours on a single charge.
