Nowadays, the consumer demands for electrical energy are increasingly growing, because this energy is present in all fields of human activity. Any company producing and distributing electric power sets two main objectives, namely: customer satisfaction and profit making. The aim of this paper is to investigate appropriate tools (multi-criteria decision making methods) aiding decision makers to achieve...
The electrical substation components are often subject to degradation due to over-voltage or over-current, caused by a short circuit or a lightning. A particular interest is given to the circuit breaker, regarding the importance of its function and its dangerous failure. This component degrades gradually due to the use, and it is also subject to the shock process resulted from the stress of isolating...
Competing risk problems involving degradation failures are becoming increasingly common and important in practice. In this paper, we investigate the modeling of competing risk problems involving both catastrophic and degradation failures of oil circuit breaker under normal functioning conditions. Using a real case study, shocks highlighted by short-circuits frequency and magnitudes are modeled using...
