  • Product Features
1. Partial discharge detection: partial discharge detection of high-voltage electrical equipment, 2 or 4 channels of independent data acquisition (non channel conversion), synchronous signal sampling, synchronous sampling, processing, display, 2 or 4 windows of independent display of partial discharge measurement results.
2. Provide a variety of anti-interference measures in the complex field: unique antenna noise gating, signal polarity discrimination, dynamic anti-interference, digital analog hybrid filtering and other anti-interference functions. Various anti-interference measures can be flexibly combined and applied, which can effectively reduce the impact of interference on the measurement results and facilitate accurate measurement in the complex environment.
3. Multiple analysis functions: phase analysis, fingerprint, spectrum analysis, three-dimensional and two-dimensional image analysis are available. The software can also conduct detailed investigation and analysis of a certain phase waveform, enlarge and reduce the window at will, or conduct spectrum analysis on this section of data. Analyze the spectrum content of the discharge waveform, so as to make the discharge waveform more comparable, Comprehensive statistical analysis of test data to reduce the influence of instability factors on test results.
4. Automatically generate test report: automatically save test data and waveforms at any time, automatically and regularly, and can redisplay and analyze the saved test records in the past, generate test report, and provide reference for later data analysis.
5. Portable mobile: it is suitable for mobile use on the site with complex environment. The display screen is a high-resolution touch screen, which is convenient for field operation.
6. Gain range: each channel is adjusted separately, and the waveform display can be adjusted smoothly at any time without affecting the measurement results.
7. The special or random waveform can be captured and analyzed in detail.
8. Open window in any phase, single window or double window, and open window freely within 360 degrees.
9. Internal and external synchronization can be selected at will, with zero mark indication and phase resolution function.
10. Single discharge pulse waveform analysis and determination of discharge properties, single capture and capture of special or random waveform and detailed analysis.
