Özet:

 

This paper presents a theoretical dynamic model based on   the Hampton criterion and Mayr's equation for predicting the critical values   of flashover on the surface of nonuniformly polluted cap and pin porcelain   insulators. The nonuniform pollution layer on the surface of the insulator,   the number of disk insulator units, and the geometry of the insulator such   as diameter and ribs are the important factors used for prediction. Two   types of pollution layer configuration, linear and graded, are   introduced as nonuniform pollution layers. The influences of the nonuniform   pollution layer on critical flashover voltage are investigated. Furthermore,   a random value is added to the surface discharge length during propagation   in order to consider the effects of the wind and thermal convection on   surface discharge length. The specifications of a real porcelain disk   insulator are used in the model. Finally, the estimated results of the   proposed model are compared with the measured data of the tests in order to   validate the proposed model.
