Application of statistical analysis in the asset management decision process

Abstract

One of the tools to answer some typical asset management (AM) questions is the use of statistical analysis of life time data of high voltage components. When life time data of components is available, statistical analysis can be performed. The analysis can give information about the failure rate of components, expected failures in the future, conditional remaining life estimation and influence of maintenance- and/or replacement strategies. In this contribution the general approach of the analysis is shown together with some examples of typical AM questions for typical high voltage components. Statistical analysis is used to find answers to these questions.
