◆ After digital processing of signals, the HD5000 type partial discharge detector uses an LCD display instead of the traditional oscilloscope tube display.
◆ Operation is exactly the same as traditional analog partial discharge test instruments, easy to learn.
◆ Free selection of ellipse, line, and sine display modes
◆ Digital windowing technology is adopted to avoid the influence of interference on measurement.
◆ Arbitrary phase windowing, single window or double window optional, ellipse rotates 150 degrees.
◆ Can freeze and save the current discharge pattern for static observation and analysis of partial discharge pulses.
◆ Can save the current discharge pattern to achieve traceability of test results.
