Abstract

The application of infrared thermography (IR scanning) in utilities for aerial surveys, inspection of substation and overhead connections and equipment is well known. This paper describes a new application for infrared thermography--examination of underground secondary connections in manholes and service boxes. The analysis of over 300 potential failures detected by IR scanning, to date, has shown failure mechanisms in all which eventually would have caused the connection to fail. Infrared scanning of undergound secondary connections has been shown to be a viable method for preventive maintenance. Potential failures are detected before the occurrence of an emergency (customer outage) condition. Analysis of these potential failures by QA & R provides a check on the efficacy of the operator, equipment and procedure.
