Abstract
According to available statistics, about 70% of high voltage transmission line failures result from inappropriate
performance of insulators in pollution prone environments. This has been observed quite significantly in the
state of Gujarat, which is the one of the most industrially developed states in India. A few years ago, a report
on frequent power failures in the Kutchh area due to insulator failure was published1l.ln the present study,
ten locations were selected across Gujarat State. In these ten locations, three locations covered industrial
zone, two covered desert areas, two locations were in coastal salty zone, one was a nearby cement factory
and two were located in agriculture zone. It has been found out that there could be a correlation between the
rate of pollution deposit andthe variation in environmental parameters. The study reveals that the polymeric
non-ceramic insulators retain their hydrophocity under different pollution levels thereby suggesting their
fitness for use under different pollution conditions found in Indian grids.
