21. 2121 * Anthony Smith, Reliability Centered Maintenance. Focus Area: RCM Reliability Centered Maintenance — 1998 Industry Results  The principles of RCM*: –Preserve system function –Evaluate loss of function –Prioritize the importance of failure mode –Determine if PM task is effective  Benefits described by participants: –Consistent targeted maintenance with a sound technical basis. –Decreased maintenance costs with no decrease in reliability. –Reduced maintenance intervals and buy-in by field personnel.  44% of companies have introduced RCM into substation area.  Most are in planning stages (27%); only 9% in pilot and 14% in rollout.  Obstacles include: computer systems, lack of historical data, costs/resources, data storage.  RCM system development: in house 35%, EPRI 11% Pepco Comments Pepco has looked at the EPRI model and is currently changing the work schedule so that it is based on performance. The Failure Mode does not work for Pepco due to the redundant design.
