Abstract :
An artificial contamination method for
hydrophobic polymer insulators was newly developed, which can
provide a uniform contaminant layer similar to thc natural one
neither by damaging the polymer surface nor by adding any
chemical agent to the conventional contamination slurry.
Using this method, basic contamination withstand voltage
characteristics of polymer insulators were investigated comparing
with those of porcelain insulators. The results show that although
hydrophobic polymer insulators generally have exccllent
contamination withstand voltage characteristics critical reduction
of withstand voltage occurs sometimes undcr rapid and heavy
wetting and contamination conditions.
