Method using hardware and functional method to divide power transformer composition

The risk of failure and status maintenance decision methods and other key issues in-depth study: ① power  electric meter  failure modes and effects analysis. Power transformer on the structure and function of depth and detailed analysis, based on the method of using a combination of hardware and functional method for power transformer  electri cenergy meter  is divided, and then the various components of all possible failure modes and effects of in-depth analysis, to avoid a complete according to the system structure failure mode and effects analysis of the complexity of the transformer reliability and fault risk assessment basis. ② based on multi-characteristic parameters of the power transformer fault probability comprehensive evaluation method.
