Abstract :
Tests to show the attenuation of voltage and charge phenomena between corona sources located in power transformer windings and the terminals of the transformer are described. The attenuation of corona, or simulated corona, in both major and minor insulation is considered. A circuit developed specifically for the purpose of simulating corona is detailed and its application in the tests is described.
