This report describes research conducted to determine the contamination performance of {sup 138} kV transmission line insulators utilized by Florida Power and Light Co. Although test results for both ceramic and nonceramic insulators are reported, emphasis is placed on the performance of nonceramic line posts before and after artificial aging. Since it was not possible to obtain nonceramic insulators that were aged in the same environment and for the same amount of time, there was a need to develop an accelerated aging chamber in order to age these insulators artificially. The aging cycle for these tests is designed to represent the severe coastal climate of Florida. Aging is judged by physical observations, leakage current analysis during aging, analytical material measurements and contamination flashover voltage. Flashover performance is evaluated as a function of contamination severity as determined by equivalent salt deposit density (ESDD). Radio interference (RI), television interference (TVI) and audible noise (AN), during contamination flashover tests, are also described.
