MEPD-5030 Multifunctional Partial Discharge Tester Send email to us

1) It can quickly detect the partial discharge of high-voltage electrical equipment, especially high-voltage cables, on site. It is easy to use, small in size, light in weight and easy to carry.
2) The circuit design of the partial discharge detection sensor uses advanced radio frequency signal processing, high-frequency signal processing and weak signal processing technology, and uses 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) It combines ultrasonic waves, transient ground waves, high frequency and ultra-high frequency to jointly detect partial discharge signals.
4) Built-in non-contact air sound sensor, which can be configured with an external surface-mounted ultrasonic sensor.
5) It has multiple windows such as phase line, PRPD, PRPS, etc. to analyze partial discharge test data.
6) It supports data storage, viewing, deletion and other functions.
7) It supports waveform data recording function.
8) It supports multi-level threshold setting for attention and alarm, and provides intuitive prompts for problems through different amplitude colors.
9) It is powered by a large-capacity lithium battery and can work continuously for 6 to 8 hours on a single charge.
10) Use Linux as the embedded operating system to facilitate later function expansion and integration of Internet of Things technology.
