Abstract :
This paper presents the results of round robin tests performed
to evaluate the electrical performance of Room Temperature
Vulcanizing (RTV) silicone rubber coatings used for
improving the contamination performance of outdoor
ceramic insulators. The tests, performed in six different
laboratories, included several salt-fog chambers and a
tracking wheel. Most test facilities were equipped with an
on-line data acquisition system for measurement of leakage
current activity. Four generic formulations of RTV silicone
rubber coatings applied on ceramic rods were evaluated. The
results indicate a general consensus in the ranking of the
coatingsʹ leakage current suppression capability, despite the
variation in the experimental conditions employed. This
suggests that guidelines for a laboratory test for evaluating
the RTV coating marcrialʹs electrical performance under
contaminated conditions could be developed.
