A Multivariate Decision Tree Diagnosis Method for Transformer Fault Based on Rough Set Theory
Ren Xueping · Journal of Anhui Electrical Engineering Professional Technique College · 2011
In this paper a multivariate decision tree algorithm based on roughness of rough set theory in transformer fault diagnosis is presented.This method selects generalization relative to decision attribute in transformer fault decision table as root of the transformer fault diagnosis decision tree.Then this condition attribute will be the branching node if which has the smallest roughness.A more compact and reasonable multivariate decision tree of transformer fault diagnosis is formed ultimately.Results of instance comparison test verify the effectiveness of the method.
