Switching-Surge and Dynamic Voltage Study of Arizona Public Service Company's Proposed 345-Kv Transmission System Utilizing Miniature Analyzer Techniques

Investigations were conducted of switching-surge phenomena on the proposed addition of the 292-mile 345-kv transmission lines to Arizona Public Service Company's system. In order to arrive at balanced design and operating conditions with regard to surge voltages, insulation levels, arrester protection, and switching procedures, a study was performed on a system in miniature. Data, results, and conclusions from this study are presented.
