UHF Ultrasonic Partial Discharge Online Detector

Darui Electric recommends:

  UHF Ultrasonic Partial Discharge Online Detector This device can sense high-frequency signals generated by operating equipment faults, vibrations, leaks, and electrical partial discharges. It uses a unique heterodyne method to convert these signals into audio signals, allowing users to hear these sounds through headphones and see the intensity indication on the pointer. The heterodyne principle is like a radio, accurately converting signals into sound for easy identification and understanding. The advantage of using ultrasonic technology is its ease of understanding and convenience. Ultrasound is a high-frequency short wave signal that is not directly audible to the human ear. When we use an ultrasonic full-function detector, these sounds can be fully detected. Utilizing advanced visual ultrasonic principles and exquisite sensing technology, it vividly displays discharge images and informs maintenance personnel for repair through three methods: digital, sound, and image, ensuring the safe operation of GIS.

Features

1. Comprehensively provides detection and analysis functions of internationally renowned products such as DMS and AIA. Its flexible operation and powerful spectrum analysis functions are well recognized by users familiar with such products; Ensures that the detection sensitivity of partial discharge is not affected by environmental interference;

3. Uses a German monitoring-grade UHF signal receiver. Comparative tests prove that its sensitivity in detecting UHF signals exceeds that of the UK's DMS level and has good anti-interference capability;

4. Selects AE signal sensors and amplifiers from the US PAC company (also selected by Norway's AIA company), making its sensitivity in detecting ultrasonic signals identical to AIA's;

5. Adopts a unique pulse capture technology. Unlike other similar products that require changing measurement modes, it can simultaneously obtain all information for partial discharge analysis, including the most advanced three-dimensional PRPD and PRPS spectra internationally;

6. Uses continuous pulse discrimination technology to automatically identify communication signals in the UHF band and continuous vibration noise in the AE band, eliminating the impact of sporadic interference signals on partial discharge measurement;

7. Has the function of simultaneously measuring UHF+UHF or UHF+AE signals, enabling correlation analysis of the two signals, facilitating the determination of signal sources and characteristics, and improving the reliability of detection results;

8. Configured with multiple types of sensors to meet the detection needs of transformers, mutual inductors, GIS, and other equipment.
