Abstract

Inspecting compression splices on transmission and distribution lines has long been accomplished using infrared thermography but the results have too often been disappointing. There are instances of splices failing within months of infrared inspections. An understanding of the actual condition of the splices had been `masked' by one or more of the factors discussed in this paper. A number of factors are involved, including a poor understanding of the application of the technology; inadequate training of some service providers; environmental factors; low electrical loading; the resolution limitations of the inspection equipment; low emissivity of the components, and a poor understanding of how to interpret the data.
