Abstract
1 Scope This technical specification is applicable for the determination of the AC and DC pollution flashover and withstand voltage characteristics of insulators with polymeric housing, to be used outdoors in HV applications and exposed to polluted environments. This is also applicable for insulators with hydrophobic coatings. This document refers to AC systems with a rated voltage greater than 1 000 V and DC systems with a rated voltage greater than 1 500 V. The object of this technical specification is to prescribe standardized test methods, requirements and procedures for artificial pollution tests applicable to polymeric insulators for overhead lines including traction lines, station post and hollow insulators of equipment. Available test experience with polymeric station post and hollow insulators, especially for DC applications, is limited. The proposed tests are not applicable to ceramic and glass insulators without polymeric housing, to greased insulators or to special types of insulators (e.g., insulators with semiconducting glaze). Differently to ceramic and glass insulators without polymeric housing:
The pollution performance of insulators with polymeric housing varies with the hydrophobicity condition of the surface. The specific conditions simulated by standardized tests might not represent the actual dynamic field conditions.
