Abstract


Transformer partial discharge measurement is the major projects of the transfer of power construction and preventive trials.This will combine the transformer partial discharge test of power engineering in recent years and analyze the methods and data to explore the of partial discharge testing of power engineering transformer.This paper introduces the basic concepts of partial discharge, introduction the meaning andt he development of partial discharge. Analysis the causes of partial discharge.combined with the structural of transformer to analysis partial discharge occurs inside the transformer all the weak parts. Analysis of discharge form the destruction of the insulation, thus further clarify the importance of partial discharge test.Then on the basis of the meaning of partial discharge to review of the development of partial discharge detection technology, introduced a variety of conventional test methods.On the base of theoretical analysis, the combination of on-site partial discharge testing features, details the field test program.described partial discharge test methods and the importance by Further experients. provide a valuable reference for future field trials.
