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 weather in the coastal regions of Florida. Analytical measurements quantifying the degree of artificial aging are discussed, and artificial aging is compared with service experience. Observations of audible noise and radio influence voltage during the clean fog tests are reported
