Original Partial Discharge Tester Product Features
1. The partial discharge detection system adopts a pure program-controlled working mode;
2. Full Chinese menu prompts;
3. Automatic calibration, automatic synchronization, automatic voltage recording, automatic measurement saving and playback;
4. Automatically generate test reports;
5. Two-dimensional and three-dimensional partial discharge pattern display;
6. Digital windowing technology is adopted, with strong anti-interference capability;
7. Dual-channel measurement and digital differential technology can simultaneously measure partial discharge signals from two test objects or two measurement points of one test object, making it easy to analyze the source of partial discharge signals.
Original Partial Discharge Tester
A true four-channel product that simultaneously has broadband testing and narrowband testing functions. It adopts a large-screen oscilloscope, with clear test waveform display, high-frequency elliptical scanning (power consumption less than 1 VA), large dynamic range of the amplification system, multiple frequency band combinations (nine types), auxiliary zero-marking system, linear and logarithmic dual-function pointer meters and digital meters, which can simultaneously display the discharge quantity of discharge pulses.
It has a sine wave display function. When the partial discharge instrument is combined with a capacitive voltage divider measuring impedance, it can display a sine wave synchronized with the test power supply on the oscilloscope screen. The newly added narrowband measurement function allows the center frequency to be continuously adjustable within the range of 40kHz to 1MHz, effectively avoiding interference and selecting a frequency band with a high signal-to-noise ratio for partial discharge signals to extract them. This allows test personnel to more intuitively distinguish partial discharge signals from noise.
