Research of On-Line Monitoring of Trace Moisture Content in Transformer Oil

CHEN Xin-gang,TIAN Xiao-xiao,YANG Yi,GU Liang-ling School of Electronic Information and Automated,Chongqing Institute of Technology,Chongqing 400050,China  
The distribution of moisture in the transformer and its variation in the oil are analyzed,and a detailed scheme of on-line monitoring moisture content in the transformer oil is put forward,using relative saturation and temperature as characteristic parameters. A polyimide-based capacitive humidity sensor and a temperature sensor are employed in on-line monitoring moisture content in the oil. A computer is utilized to sample and analyze the data that the sensors send out. An experiment on a test transformer confirms that the sensors can work reliably and reflect the moisture content in transformer oil accurately. The method that the paper recommends can realize the purpose of on-line monitoring.
