The influence of a camera's spectral transfer function used for observing high voltage corona on insulators

A number of previous investigations implied that there is a relationship between the high voltage electrical losses incurred by corona and the optical energy observed by solar-blind ultraviolet cameras. Furthermore, these previous investigations proved that the optical energy detected is influenced by a number of radiometric parameters such as distance and atmospheric conditions, as well as the electrical test configuration. In addition this presents the results of a study to determine the influence of a specific solar-blind ultraviolet camera's spectral bandwidth on the camera's optical measurements. This shows how to uniquely overcome limitations of a particular camera's processing output such that the spectral transfer of the camera can be measured. The aim of this paper is to stimulate and provide additional insight into the electrical losses on dielectric insulators, including the relation of the optical energy observed by solar-blind ultraviolet cameras.
