To assess the long-term performance of 72 kV and 230 kV composite long rod insulators different laboratory aging tests have been developed. This paper reports two principal diagnostic tests used to measure the performance of the insulators, the quick flashover salt fog (QFO SF), and the rapid flashover clean fog (RFO CF) tests. The aging processes were: cement coating and clean fog, salt fog, and cement coating and salt fog. Similar sets of insulators were aged also in the field for over three years, and all the insulators evaluated in the laboratory. The cement/salt fog aging process was found to be the most controllable and realistic, when the results were assessed by means of the RFO CF test.
