To improve the accuracy and sensitivity of partial discharge detectors, the following measures can be taken:
1. Choose high-quality sensors:
Choose sensors with high sensitivity and wide frequency response to capture various types and intensities of partial discharge signals.
Regularly calibrate and maintain sensors to ensure their stable performance.
2. Optimize signal processing technology:
Use advanced digital signal processing techniques such as filtering, denoising, amplification, etc. to reduce the impact of background noise and other interference signals on the detection results.
Introducing machine learning or artificial intelligence algorithms for pattern recognition and analysis of partial discharge signals to improve the accuracy and reliability of detection.
3. Improving the testing environment:
When conducting partial discharge detection, ensure that the testing environment is as close as possible to actual operating conditions to simulate a real discharge environment.
Take measures to reduce or eliminate interference factors such as electromagnetic interference and mechanical vibration in the environment, in order to improve the signal-to-noise ratio of detection signals.
4. Improve instrument accuracy and stability:
Choose high-precision, low-noise electronic components and amplifiers to improve the measurement accuracy and stability of the detection instrument.
Regularly calibrate and maintain testing instruments to ensure they maintain high performance throughout their entire lifespan.
5. Adopting multi parameter detection method:
Combining multiple detection parameters (such as electrical signals, sound, vibration, etc.) for comprehensive detection to improve the accuracy and reliability of the detection.
Through multi parameter analysis, the characteristics and location of partial discharge can be more comprehensively understood, providing stronger support for fault diagnosis.
6. Enhance the skill level of operators:
Provide professional training to operators to enable them to proficiently master the operation methods and skills of partial discharge detectors.
Improve the fault recognition and analysis ability of operators, enabling them to accurately judge the detection results and take corresponding measures.
7. Innovative technology application:
Pay attention to the development trends of new technologies and timely apply them to the research and production of partial discharge detectors.
For example, introducing new detection technologies such as ultra-high frequency (UHF) detection technology and optical detection technology to improve the accuracy and sensitivity of detection.
In summary, improving the accuracy and sensitivity of partial discharge detectors requires comprehensive consideration of multiple aspects, including sensor selection, signal processing technology, testing environment, instrument accuracy and stability, multi parameter detection methods, operator skill levels, and new technology applications. By continuously optimizing and improving these aspects, the performance and reliability of partial discharge detectors can be improved, providing strong guarantees for the safe and stable operation of power systems.
ZC-254B partial discharge detector is one of our company's most classic products, which has been highly recognized and has a leading market share since its launch many years ago. The detector has independent 4-channel, solid-state drive, user-friendly selection of front and rear four-way electrical signal channels, a brand new integrated motherboard, high frequency, and high-speed acquisition card for more stable use. The detection sensitivity is increased to 0.05pC, and the sampling rate of each channel is 80MHz. The large-sized LCD touch screen, Bluetooth wireless transmission, rich peripheral interfaces, and lighter body are more suitable for mobile use in complex environments.
This instrument is suitable for detecting and locating partial discharge of AC and DC in transformers, reactors, generators, transformers, bushings, GIS, lightning arresters, high-voltage switches, switchgear, and other high-voltage electrical equipment.
