Rational Reliability Centered Maintenance Optimization for power distribution systems

Abstract Reliability Centered Maintenance Method (RCM) currently used for maintenance optimization based on the analysis of modes of dysfunctional system failures (FMEA), and after determining the criticality of the system, an adequate maintenance plan is adopted. Following the succession of several applications of this method, in several areas, along twenty years of experience, it was proved that the use of this approach was incomplete for other analysis and evaluation criteria were completely ignored especially in electrical systems. Our view is to apply this method rationally by introducing a whole dependability study (RAMS).
