The Engineering Analysis And Research Of Fault For Power Transformer

Based on the malfunction datum of 328 power transformers (110kv or above), the paper makes the following studies by both the analysis of the datum and lots of tentative tests and presents the corresponding research results:The research on the malfunction mode classification of power transformers by the failure tree analysis method (FTA);The research on the status prediction criterion of running power transformer;The research on detective methods and criterions of the disability of the power transformer;The research on evaluation the life of the power transformer;The research on the relationship between the status estimate system and status examination & repair of the power transformer.
