The transformer fault management information system design based on the risk assessment

Abstract

Risk assessment is defined to measure the probability and security of risk resources synthetically. In this paper, risk assessment theory is employed firstly to maintenance tactics of transformer, the probability and severity of all failure modes of transformer are measured synthetically, and risk maintenance tactics of usual transformer's failure modes are obtained .Based on these, 5×5 risk matrix and 4 kinds of risk ranges are adopted to express the risk of all transformer's failure modes, and responding risk maintenance strategies are obtained; finally, a example is analysis to verify the correctness of the risk assessment frame and risk maintenance strategies. And the Visual Basic language and the Access database are applied in this paper to design the MIS of the transformer risk management.
