XD52 series of ultrasonic partial discharge detector

Applicable to tthe electric insulation of switchgear, cables, transformers, and windings in large motors and generators.

XD52 series of ultrasonic partial discharge detector:

      Partial discharges are small electrical sparks that occur within the electric insulation of switchgear, cables, transformers, and windings in large motors and generators. Partial Discharge Analysis is a proactive diagnostic approach that uses Partial Discharge (PD) measurements to evaluate the integrity of this equipment. This article describes how instruments that detect airborne ultrasound can be used to detect and evaluate partial discharge in electrical equipment.

Main Description:

Model	Name	Features description
XD5201	Ultrasonic partial discharge detector	Signal channel
XD5202	Ultrasonic partial discharge detector	Dual channel

Features:

    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.

    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.

    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.

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

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

    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.
