Pollution test of naturally and artificially contaminated insulators

Working Group D1.44 was established at the direct request of CIGRE/IEC after it was considered that there was a lack of standardisation with respect to test methods for the quick but reliable evaluation of the flashover performance of naturally polluted ceramic and polymeric insulators. The brochure proposes relevant test methods and detailed scenarios to perform the tests of naturally polluted insulators in an optimum way depending on number of insulators available.
