Porcelain versus Polymer Insulator- A Changing Era in Transmission Lines

Abstract

For the past few years with an increase in the globalization, the environmental challenges and an increase in pollution levels have become a global phenomenon as well as matter of discussion. The power transmission lines passing through transverse areas within the country as well as worldwide are facing various problems related to environment and pollution. Such an exponential increase in the pollution levels lead to frequent faults in transmission lines which finally lands to permanent breakdown of transmission lines. These breakdowns sometimes may leads to collapse of grid and are also inconvenient to everyone besides interrupting the growth of nation as well as society breakdown. Over the years engineers and scientists have made efforts to meet such threats and to overcome situations rising form the failure of transmission lines the environmental challenges and an increase in pollution levels. The scientific community proposes a solution to resolve transmission failure by adopting polymer insulators instead of conventional porcelain insulators because the demand is on increase by virtue of its proven inactive use. In this article, an effort has been made to understand difference between the two and agency would decide the type of insulators to be deployed for ensuring long life of transmission line with respect to rate of rise of pollution in country.
