DOI: http://dx.doi.org/10.1108/02656711211230526 Abstract Purpose To review cotemporary maintenance programs and analyze factory production data for an SF6 gas filled circuit breaker population. Various maintenance techniques and studies are reviewed to understand the reliability of circuit breaker models and the impact manufacturing can have on long term maintenance considerations. Design/methodology/approach Production and field event data were analyzed using statistical analysis tools. The population data was formatted so that a recurrent event analysis could be conducted to establish the mean cumulative function (MCF) by model and product family (class). Average Field Two-year Recorded Event Rate (AFTRER) is introduced and compared to
