A performance model for medium voltage equipment

This paper presents a performance model for condition monitoring, diagnostics and prognostics of Medium Voltage (MV) breakers and switchgears. Scope of the performance model is to assess the current health condition, to predict the future health condition and, possibly, to provide indications about the cause of potential failures of MV equipment. The outcomes of the performance model are then meant to provide relevant information for any successful riskbased, condition-based and predictive maintenance strategy. The performance model presented in this paper is based on the concept of "competing" failure modes. It is modular and scalable in order to take into account different scenarios of data availability (from static product nameplate data to dynamic condition monitoring and test data) and MV equipment of different manufacturers. Finally, the performance model may be easily adapted to any kind of assets.
