Abstract

Rapid urbanization and industrization in Malaysia over last two decades has resulted in increased demand for reliable electric power. The reliability in turn is greatly influenced by the grid system and its components being properly maintained. One of the important components is the high voltage insulators used in the overhead lines, substations and power stations. IV The main objective of this project is to select an appropriate insulator for 275kV Transmission Line. In order to select the appropriate insulator, the flashover mechanism, hydrophobicity characteristic and aging of various kinds of insulators that involve in 275kV transmission line will be investigated. Every insulator will be analyzed with detail observation. All the characteristics of each insulator will be recorded and the suitable one will be selected. Design of275kV insulator of transmission line has always been restricted by limited choice of material and closely linked to the development of manufacturing process. Introducing the new designs of insulator has often been complicated. However, the types of insulators that have been used in high voltage transmission line are porcelain, glass, non-ceramic and silicone rubber Ethylene Propylene Diene Monomer (EPDM)
