Dynamic discriminant analysis for predictive maintenance of electrical components subjected to stochastic wear

摘要

An optimal maintenance program for electrical power system components should be based on their reliability. Since, for components characterized by high reliability and cost such as HV circuit breakers, available statistical data are in limited number, a physical model for their Ageing is opportune. In the paper a Predictive Maintenance Program (PMP), for determining When a HV circuit-breaker should be rebuilt, is formalized; it is based upon an adequate stochastic Model of electrical wear associated with breaking operations due to system faults.
