Influence of Spectral Transfer Function of Ultraviolet Imager on Corona Discharge Detection of Insulators
Research suggests that there is a correlation between the electric energy loss of the high voltage corona and the optical energy measured by solar-blind ultraviolet camera. What’s more, the optical energy is influenced by some radiometric parameters such as distance, atmospheric conditions, and the test configuration. Moreover, the spectral bandwidth of a solar blind ultraviolet camera also affects the measurement of optical energy. In order to overcome the limitations of the camera’s output and measure the spectral transfer function of the camera more accurately, the principle of corona detection by solar-blind ultraviolet camera are proposed, and then carries out simulation and experimental about the spectral transfer function. Finally obtains the relationship between the energy of high voltage corona discharge and the optical energy observed by solar-blind ultraviolet camera. And the relationship between the energy of high voltage corona discharge and the light energy measured by a daily blind ultraviolet camera is finally obtained.
