A study was undertaken to investigate the surface tracking phenomena in different polymeric
insulating materials. The polymeric materials chosen were silicone rubber (SR), ethylene …

Epoxy resins have excellent mechanical and electrical properties; thus, they are commonly
preferred in the electrical {electronic sector as insulation materials. These insulation …

Most polymer outdoor insulator may suffer from surface tracking phenomenon due to the
leakage current that flows on the insulator surface. The magnitude of leakage current …

The increased use of polymer insulators on the overhead electrical power system has led to
many designs of insulators, with many profiles and materials, but the performance has not …

Surface tracking is one of the major breakdown mechanisms observed on polymeric outdoor
insulators. Continuous discharges on the surface of the insulator cause hot spots on certain …

Electrical aging of insulators is associated with a wide variety of phenomena such as
breakdown, discharges, treeing, electron interactions with charges, phonons, matters, etc …

Environmental pollution can cause the insulator material to become progressively coated
with dirt and chemicals in the long run. In the presence of wet atmospheric conditions, the …

This research work is carried out to investigate the surface degradation of modified
polymeric electrical insulator when tested under inclined plane tracking method. The test …

Polymer insulating materials are widely used in power distribution and transmission systems
for their good dielectric properties such as light weight, low cost, and good contamination …
