Abstract: With the increase in operating voltage of transmission system to transport large amounts of power to meet increased demand switching surges became governing factor in the insulation design of EHV and UHV systems. Insulation failure probability under switching surges that is switching surge flashover rate (SSFOR) is the main concern in the switching surge design of transmission lines. In this paper, SSFOR of 1200kV UHVAC transmission line under switching surges which are generated during energization of no-load transmission line is estimated. 
Keywords: Electrical stress, Insulation strength, SSFOR, Switching Overvoltage, UHVAC Transmission line.
Scope of the Article: Wireless Power Transmission
