ABSTRACT:
There is disclosed a method for determining the location of an arc or corona as occurring in a high voltage power supply. The technique utilizes sheets of sensitive photographic film which are placed between printed circuit boards of the supply or between high voltage components and the metallic chassis walls of the power supply. During supply operation if an arc or corona occurs the film becomes exposed. The amount of exposure is determinative of the magnitude of the arc as well as indicative of the location of the arc or corona discharge which location and magnitude is determined by developing the film after supply operation. In this manner a comparative analysis of the amount of corona or arc as a function of time can be made by comparing the film density after photographic chemical development. The technique enables one to, therefore, accurately determine not only the magnitude of the arc or corona discharge but the exact location of the same.
