A technique based on IR Thermography measurements is proposed to estimate realistic
values of electric hardware failure rates corresponding to secondary failures,
that is, those caused by past or present out-of-tolerance or abnormal operating conditions.
The technique allows the establishment of useful correlations between these
failure rates, and the corresponding relevant thermal patterns as mapped using JR
Thermography. The technique is applied to practical cases of secondary failures in
typical AC and DC electric power network components having to do with failure modes
due to abnormal stress, corrosion, and erosion. The application of this technique to
fault and failure diagnosis, and both Reliability, Availability, and Maintainability
(RAM) Analysis and Probabilistic Risk Assessment (PRA) of electric power networks is
also briefly discussed.
