TRANSMISSION LINE POLYMERIC INSULATORS LEAK CURRENTS AND PERFORMANCE

.
(1992)

Abstract

The surface of polymeric insulators possess a more dynamic behavior than those of ceramic or glass insulators and undergoes through a series of transitions which may be crucial for discharge activity and which may increase the risk of flashover and surface damage. The results obtained from the measurement of leak currents and the performance of commercial polymeric insulators, belonging to two different families Ethylene-Propylene Rubber (EPDM) and Silicone Rubber (SR), which were exposed to HVDC and HVAC at the field station of Anneberg during a period of three years ( 1989-1991 ), show an essential difference which may be attributed to the polymeric material family.
