This equipment is designed for UHV AC and DC engineering research and development. It is suitable for the partial discharge measurement of various high-voltage electrical equipment, covering full voltage and capacity grade transformers, reactors and other partial discharge (PD) on-site detection and diagnosis of multi-function, reactor Interference type, AC and DC dual-purpose, four-channel partial discharge detection system, representing the most advanced technology of international and domestic partial discharge detection.

Product Features

1. The four-channel independent notification sampling technology is adopted to ensure uninterrupted and non-lost periodic sampling for each channel. The uncertainty index is better than 3% of the range, and the detection signal is complete, true and reliable.

2. Full program control, large dynamic automatic calibration, automatic power synchronization, automatic voltage measurement, automatic recording function, combined with recording function, combined with automatic infinite time recording and storage function, can store and playback waveforms at any time

3. Independent dynamic digital filter FIR function, with high anti-interference level

4. Multiple display modes of ellipse, straight line, sine, dot matrix, multiple analysis and statistical maps (NQ-Ф, QT-Ф, N-Ф, Q-Ф three-dimensional and two-dimensional maps) are simultaneously displayed on the same screen, and the analysis and diagnosis are more improved. To be effective and fast

5. The software system based on the Windows platform is easy to operate and powerful; the one-key recovery function ensures the stable operation of the equipment

6. Imported double-layer aluminum-magnesium alloy case, portable integrated design, strong and light
