The scientific approach here has enabled a critical analysis of time-based maintenance variables to identify areas where the underlying principals of the maintenance policy can be challenged.

The methodology was applied to distribution switchgear maintenance as a test bed prior to roll-out into the business. The project investigated the potential for improvement to our maintenance strategy for distribution switchgear using the RCM framework whereby targeted maintenance based on failure modes is carried out in order to improve reliability rather than maintenance being strictly time or interval based.
