A New Method of Rough Set Decision for Transformer Fault Diagnosing
Dong Chun-hui · Electrical Measurement & Instrumentation · 2010
The questions were found when the DGA new rules were applied in the practice.So a new method of rough set decision of transformer fault diagnosing is brought forward through combining rough set with DGA in the paper.Then better greedy algorithm is used in the course of discretization of continuous attributes in order to assure performance of result of discretization.Finally decision rules of transformer fault diagnosing are gained and in the result the new method has higher exact ratio.
