Experience of RCM for substation equipment at Fingrid

摘要

This paper describes the experiencies and results of performing a reliability centered maintenance (RCM) analysis for substation transmission equipment. The RCM analysis was used to evaluate the maintenance policies of circuit-breakers, disconnectors and power transformers. Fault data helped to perform analyses by giving a valuable information of a long-term behaviour of equipment As a result of the analyses some service intervals were extended.
