Transformer insulation system is an important part of power transformer.To a great extent,it defines the re-liability and economy of transformer.Partial discharge is one important reason of insulation deterioration in transformer, which is also an important feature of transformer insulation condition.This article analyzes the reason of partial discharge phenomenon,introduces several kinds of transformer partial discharge on-line monitoring methods,and carries on the com-parison to these methods.An optimization on-line monitoring method is used to get the three-dimensional map of transformer partial discharge.
