In this article, an innovative approach to assess the risk of uniform/non-uniform pollution and wet high voltage glass insulator is proposed. The assessment is based on a new index, named as Rhi, which is derived from the 3rd, 5th and 7th harmonics of the leakage current. Two 33 kV strings of cap an...
