Abstract

Improvements in commercial IR thermal imaging equipment and advances in the related data and image processing capacities make differential infrared thermography (DIT) a highly promising tool for condition monitoring and predictive maintenance of electronic, electrical, and mechanical elements. The controlled and systematic application of DIT can dramatically improve the reliability, maintainability, and operational life of these elements throughout the power generation and distribution community. This paper describes a program initiated by the Electric Power Research Institute (EPRI) Nondestructive Evaluation (NDE) Center to apply DIT to operating elements within a power generating station environment. It traces the selection of candidate elements at some of EPRI's member facilities, the implementation of exploratory measurements on selected candidates using available on-site infrared imaging equipment and the analysis of significant findings on one specific critical element. Finally, a summary of the advantages and limitations of DIT is provided along with a description of several variations of the technique.
