Abstract
The air clearance of the transmission tower is determined by the switching overvoltage of the system, and the insulator length is determined by contamination design. This paper described the switching overvoltage analysis result of 500 kV system and air clearance design. The overvoltage include fault initiation, fault clearing, closing and reclosing overvoltages. We illustrated the contamination design example, air clearance design of a tower considering swing angle of the conductor.
