Features and Advantages
1.After the partial discharge signal is digitized, the liquid crystal display is used to replace the traditional oscilloscope display.
2.The operation is exactly the same as the traditional analog partial discharge test instrument, which is simple and easy to learn.
3.Freely select ellipse, straight line and sine display mode
4.Digital windowing technology can avoid the influence of interference on measurement.
5.Any phase windowing, single window or double window optional, and the ellipse rotates 150 degrees.
6.It can freeze the current discharge map, and observe and analyze the static partial discharge pulse.
7.The current discharge spectrum can be saved to realize the traceability of test results.
