Markov models are a well established technique widely used for modeling deterioration processes of the electric power equipment and in reliability analysis. Recently, several papers using Markov and semi-Markov models have been published addressing the issue of the calculation of the remaining life, future failure rates and the probability of failure of power equipment. This paper focuses on one such...
This paper deals with the ageing behavior of different circuit-breaker types. Furthermore, the model simplifies the condition control of pieces of equipment and provides the asset manager with information about the yearly capital and operational expenditures (CAPEX and OPEX). Capital expenditures include new installation costs in consequence of replacement and grid enlargement and operational expenditures...
Maintenance managers of today's electrical distribution systems are faced with the problem of where their maintenance resources will be utilized best. In previous work the authors have developed a method for maintenance policy optimization for electrical networks. This paper presents results from an application study performed for a distribution system, including both urban and rural parts, for this...
