ACCELERATED AGING AND FLASHOVER TESTS ON 138 kV NONCERAMIC LINE POST INSULATORS

(1992)

Abstract

The behavior of 138 kV nonceramic line post insulators is investigated by means of clean fog tests conducted before and after aging in a specially designed accelerated aging chamber. The laboratory aging cycles are justified on the basis of actual veather in the coastal regions of Florida. Analytical measurements quantifying the degree of artificial aging are discussed and comparisons of' artificial aging vith service experience are presented. Observations of audible noise and radio influence voltage during the clean fog tests are reported.
