Online monitoring of insulating oil chromatography technology is an important part of condition-based maintenance of transformers,and has been widely used in practical projects,including specific film type,and headspace style. However,the method is imperfect in data reliability and repeatability. Aiming at these problems, an on-line monitoring system was designed by using photoacoustic spectroscopy to monitor the fault characteristics of gas contained in oil of transformer so that real-time monitoring and fault diagnosis of transformers could be realized. The new method was adopted to several key steps of the system design,which achieved a technological innovation for transformer faults on-line monitoring.
