Research on evaluation of transformer online monitoring data and experimental data

At present, the state of transformer equipment is evaluated to carry out maintenance, the power cut test is usually used to obtain the state of transformer equipment. But the blackout experiment generally has a long period of time, which is far from meeting the needs of current real-time control of equipment state. The application of on-line monitoring in power field enriches the methods of equipment monitoring. By pretreatment of on-line monitoring data, classification and fusion evaluation of on-line monitoring data and test data, the status of transformer can be better evaluated, which is conducive to targeted maintenance work.
