Features

• Analysis and diagnosis

    Integrating of the German AIA, the United Kingdom DMS and other international well-known detection and analysis features and combined with our spectrum analysis and filtering techniques, our overall technology has reached the international advanced level.

• High sensitivity

     With frequency selective measurement function, it can be easily selected the signal band of the best signal to noise ratio for measurement, to ensure that the detection sensitivity of partial discharge to avoid environmental interference.

• Strong anti - jamming technology

     With powerful frequency spectrum analysis and filtering techniques, it reflects the spectral components of interference signals in real time. Narrow-band filtering, in the condition of no loss of real PD signals can reduce background interference by 60% to 90%.

     Using a combination of pulse identification technology, it identifies automatically the continuous vibration noise in AE band; exclude the influence of sporadic interference signals on the partial discharge measurement.

• High sensitivity

     Selecting the most advanced signal sensors (American PAC's AE signal sensors) currently, the detection sensitivity of ultrasonic signal reaches world leading level.

• Easy to use

     Using vitro detection technology, simply put AE sensor on the metal to do the partial discharge measuring.

• Powerful software

     Chinese software analysis system based on WinCE5.0 platform, with processing, analysis, storage, communications, printing and other functions; full touch screen operation, battery-powered, can be easily achieved online inspection.
