Fault-locating Oriented Multi-level Analysis Of Power Transformers

The research and application of the location of the faults failure is still at an exploratory stage .In this paper, a multi-level analysis model of transformer failures for location-oriented is established on the basis of the nature analysis of the transformer failures, In the model a variety of effective means are used to carry out transformer fault step by step .and the model will be very utility for transformer failure in practical. In addition, In the paper a multi-level analysis model of transformer failures for location-oriented is established based on SVM, the model made full use of the advantages of the support vector machine that it has a good deal with small size sample problem , which combined the oil chromatographic results with the electrical experiments through the reduction , established a mapping between fault and attribute variables .Experiments show that the method can accurately point out the fault location of the transformer.
