Product Features

After the partial discharge signal is digitized, a liquid crystal display is used to replace the traditional oscilloscope display.

The operation is the same as traditional analog partial discharge testing instruments, simple and easy to learn.

◆ Free selection of ellipse, line, and sine display modes

Adopting digital window opening technology can avoid interference affecting the measurement.

Open windows at any phase, choose single or double windows, and rotate the ellipse 150 degrees.

◆ It can freeze and save the current discharge map, and observe and analyze partial discharge pulses statically.

◆ The current discharge map can be saved to achieve traceability of test results.
