Switching Surges, Part III: Field and Analyzer Results for Transmission Lines Past, Present, and Future Trends

During and since the preparation of [2] and [3], many field investigations concerning transmission line switching surges have been conducted. These have obtained experimental surge data on modern high-voltage transmission lines and configurations using modern circuit breakers with various means of switching surge control. It is one of the purposes of this paper to summarize and evaluate these field results. Additional purposes are enumerated.
