System Components

IN-309 Transformer Acoustic Vibration Online Monitoring SystemIt consists of high sensitive contact vibration sensor (optional triaxial), sound pattern acquisition and analysis terminal and background of sound pattern diagnosis and analysis system.

system function

The IN-309 Transformer Acoustic Vibration Online Monitoring System is an advanced monitoring solution designed for power systems, aiming to achieve a comprehensive assessment of transformer health by monitoring the transformer's acoustic vibration data in real time. Highly sensitive vibration sensors are capable of capturing weak acoustic signals during operation and support wide-screen signal acquisition to ensure coverage of the acoustic frequency range of all possible products of the transformer. The analysis terminal integrates a high-performance data acquisition and high-capacity storage unit with a built-in intelligent algorithm to automatically identify abnormal signals. The system is able to analyze the sound vibration data in depth and generate diagnostic reports.

Highly sensitive vibration sensors: As the "tentacles" of the system, it is installed in the key parts of the transformer, and can keenly capture the extremely weak vibration signals generated during the operation of the transformer, which contain information about the operation status of the windings, cores, and other components inside the transformer.
Voiceprint Acquisition and Analysis Terminal: It carries the burden of signal aggregation and initial processing. It collects vibration signals from multiple highly sensitive vibration sensors and converts them into sound pattern data for easy analysis. Through the use of fast Fourier transform and other algorithms, the acoustic data is spectrally analyzed to extract key parameters such as frequency and amplitude.
Sound monitoring and diagnostic system software: It is the "intelligent brain" of the whole system. It receives the processed data from the acoustic pattern acquisition and analysis terminal, and compares it with the massive database of acoustic pattern characteristics under normal operation and various fault states pre-stored in the system. Using pattern recognition, machine learning and other advanced technologies, it intelligently judges the current operating status of the transformer, and once abnormalities are found, such as loose windings, core magnetostriction abnormalities, etc., it can quickly issue an early warning and give preliminary diagnostic results of the type and severity of the fault.
The system has real-time, high sensitivity, non-intrusive and other significant advantages, can not affect the normal operation of the transformer, 24 hours uninterrupted monitoring of its operating status. Through the continuous analysis and trend prediction of acoustic vibration data, potential transformer faults can be found in advance, nipping the fault in the bud, significantly reducing the economic losses and social impact of equipment failure and shutdown, and strongly guarantee the safe, stable and reliable operation of the power system.
