Abstract [en]

The Swedish traction power supply system (TPSS) has approximately 134 frequency converters; there are two main types, static and rotary, with ten different models. Previous work performed a Reliability, Availability, and Maintainability (RAM) analysis of the converters to estimate their performance. The aim of this article is to use these RAM components to rank the converter models and identify the models that need more attention to improve overall operational availability. The study finds that the performance factor aggregated from IEEE Std 762 indexes can rank the converters. Furthermore, the paper has been found that the rotary models Q48 and TGTO have a low performance from RAM point of view.
