Flashover phenomenon: an analysis with influence of the thickness of the layer pollution of the high voltage polluted insulators
(Institute of Electrical and Electronics Engineers (IEEE), 1994-12-01)
Results of the analysis of dynamic behavior of flashover phenomenon on the high voltage-polluted insulators are presented. These results were taken from a mathematical and an experimental model that introduce the variable ...
Análise comparativa entre isoladores elétricos vítreos, cerâmicos e poliméricos em linhas de transmissão de energia elétrica
(BrasilUFSMCentro de Tecnologia, 2022-08-25)
In the vast majority of cases, when consumers think of an electrical power system, the importance that electrical insulators play in the process of transmission and distribution of energy is
often overlooked. However, ...

Silicone insulators of power transmission lines with a variable inorganic load concentration: Electrical and physiochemical analyses
(Elsevier B.V., 2014-04-01)
Polymeric insulation is an increasing tendency in projects and maintenance of electrical networks for power distribution and transmission. Electrical power devices (e. g., insulators and surge arresters) developed by using ...
Theory of electrical characteristics for metal-oxide-insulator Schottky barrier and metal-insulator-metal structures
(1990-12-01)
The metal-insulator or metal-amorphous semiconductor blocking contact is still not well understood. Here, the intimate metal-insulator and metal-oxide-insulator contact are discussed. Further, the steady-state characteristics ...
