Basappa, Subba Reddy and Kumar, Udaya (2012) Simulation of surface and volume stress for high voltage transmission insulators. In: International Journal of Computers & Applications .Full text not available from this repository.
The bulk of power transmission from the generating stations to the load centres is carried through overhead lines. The distances involved could span several hundreds of kilometres. To minimize line losses, power transmission over such long distances is carried out at high voltages (several hundreds of kV). A network of outdoor lines operating at diﬀerent voltages has been found to be the most economical method of power delivery. The disc insulators perform dual task of mechanically supporting and electrically isolating the live phase conductors from the support tower. These insulators have to perform under various environmental conditions; hence the electrical stress distribution along the insulators governs the possible ﬂashover, which is quite detrimental to the system. In view of this the present investigation aims to simulate the surface electric ﬁeld stress on diﬀerent types of porcelain/ceramic insulators; both normal and anti-fog type discs which are used for high voltage transmission/distribution systems are considered. The surface charge simulation method is employed for the ﬁeld computation to simulate potential, electric ﬁeld, surface and bulk/volume stress.
