documented cases where infrared thermography has
been used as a predictive maintenance tool in
determining potential problems with breakers while in
service. Follow-up analysis by the circuit breaker
manufacturer has generally validated mill maintenance
decisions to remove a breaker from service and replace
it, based on infrared scan results. Periodic infrared
scanning used as a tool in identifying potential problems
with sealed molded case circuit breakers will be
discussed. This and other breaker off-line testing
methods used at this site will be reviewed. Finally, overall
reliability improvement and impact on the results of the
existing mill-wide safety compliance programs will be
summarized.
