Before any overhead energy line can be implemented a thorough investigation and study should be carried out to ensure that the most practical route is chosen. There are two principal kinds of higher voltage insulators employed on overhead energy lines, suspension insulators and post insulators to function with the energy transformers Generally porcelain insulators are utilised for both a post insulator and a suspension insulator there is also the option for glass insulators.
The surface of the insulator should also be glazed sufficient so that the water will not be traced on it. Porcelain ought to also be kept totally free from porosity considering that porosity is regarded to be the main cause of deterioration of the material's dielectric home.
Few variables responsible for the failure of higher voltage insulators includes the degradation of dielectric functionality over the years of service, and cracks and structural harm in ceramics and glass insulators that may possibly happen in the insulators.
When subjected to a high sufficient voltage, insulators suffer from the phenomenon of electrical breakdown When the electric field applied across an insulating substance exceeds in any location the threshold breakdown field for that substance, the insulator abruptly becomes a conductor, causing a large improve in existing, an electric arc via the substance.
Upkeep concerns associated with the management of aging porcelain insulators and related inspection fees are driving some utilities to question the use of porcelain insulators, although life-cycle expense considerations and ease of inspection linked with toughened glass insulators are steering other utilities toward this latter technologies.
