The Study of Dielectric Strength of External Insulation Substations in Polluted and Humid Condition

Article Preview

Abstract:

Comparative study of impact of insulators surface pollution by magnesium silicious proppant powder and cement flour was performed in the present article. Studies were performed both for the case of charge development along polluted surface and polluted wetted surface of the insulators.
