Abstract:

As the voltage level and capacity of the power transformer is rising, its operation safety and reliability is of increasingly importance. At present, many power plants have installed oil chromatogram online monitoring device on the transformers. Through the daily monitoring and data analysis, the hidden trouble existing in the equipment can be effectively found. It mainly introduces the source of chromatographic fault gas and introduces the method of fault diagnosis. It also analyzes two cases of oil chromatographic anomalies which provides reference for operation and maintenance personnel.
