UHV Transmission Design Requirements - Switching Surge Flashover Characteristics of Extra Long Air Gaps

This paper presents data on performance of air gaps of up to 29 meters, which is beyond any previously reported. The data is raw data without any endeavor being made to compensate for the many atmospheric variables which could affect the results. However, many of these atmospheric conditions were recorded and are reported herein for future analysis and comparison with the results from other test projects.
