1. Using the Windows system operating platform, you can freely choose ellipse, straight line, sine wave display, two-dimensional, three-dimensional graphic analysis mode, spectrum window, Q-V-F three-dimensional characteristic window, and static detailed measurement, observation and analysis of partial discharge pulse of one-cycle test voltage . 2. Digital windowing operation can be carried out, windowing in any phase, single window or double window is optional, and the ellipse is rotated 360° to avoid the influence of interference on the measurement. 3. Multi-channel measurement and digital differential technology can flexibly form a pulse polarity discrimination or balance measurement loop, effectively suppressing interference pulse signals. 4. Advanced spectrum analysis processing can effectively reduce background interference. 5. With multiple input channels, the six partial discharge signals (expandable) of the test sample can be measured at one time to facilitate the analysis of the source of the partial discharge signals. 6. Under the full Chinese character operating platform, it can conveniently perform frequency band selection, gain conversion, spectrum analysis, and two-dimensional and three-dimensional graphic display. 7. The system can also save and print a single graph, and save continuous time graph data for analysis.
