Sensor Information Fusion Technology Applied On The Transformer Fault-Line Monitoring

Based on the advantages of sensor information fusion technology Such as fault-tolerant and complementary nature, real-time, high accuracy, low cost, etc., an proposal is given that this technology can be applied to monitor the transformer fault-line trouble. The physical performances of the transformer fault are analyzed. A method based on the surface fitting of multi-sensor data fusion is studied. The fusion processing and analysis for the pressure and temperature monitoring data of a pressure sensor on the transformers top were given. Results of the analysis indicated that sensor data fusion technology has more capabilities in the transformer fault-line monitoring system than the traditional online monitoring.
