Analysis of Flashover Voltages of Disc Type Insulator under Artificial Pollution Condition (TECHNICAL NOTE)
Through this paper work we have analyzed the effect of different contaminants on the flashover by creating artificial pollution condition, considering the natural condition where more than one salt as contaminant deposits on the surface of insulator at a time, under the wet condition that cause flow of highly leakage current, that leads to flashover. We choses the mixture of different salts, so...
متن کاملComputation of AC flashover voltage of polluted HV insulators using a dynamic arc model
Flashover of polluted insulators is still a serious threat to the safe operation of a power transmission system. Despite the extensive investigations carried out on the pollution performance of the insulators, the flashover characteristics are not well understood. Recent theoretical and experimental research on polluted insulators is yet to yield a perfect generalized mathematical model which c...

High voltage insulators form an essential part of the high voltage electric power transmission systems. Any failure in the satisfactory performance of high voltage insulators will result in considerable lo...
متن کاملLeakage Current Based Thermal Modeling of Glass Disc Insulator Surface
The stability of transmission lines relies on the health of the insulators, such as glass string insulators, which may occasionally flashover during an overvoltage. The likelihood of flashover increases notably when the glass insulator is wrapped by a wet contaminant layer. In this paper a study of the surface thermal profile of glass disc insulators insulation had been carried out for both cle...
متن کاملDesignation of an Indicator for flashover prediction of porcelain and glass insulators based on experimental tests.
Flashover of polluted insulators in contaminated areas is one of the most important factors influencing the operation of transmission and distribution lines and finally line outages. Therefore, it is essential to prevent and detect flashover in the insulators. Hence, utilizing the insulator status monitoring systems and predicting their functions have absorbed a lot of attention over the recent...
