Results from the First Year Operation of Project EHV

Abstract

Project EHV was operated successfully and almost continuously at the 500-kv level for the first year of tests starting in December 1960; operation is continuing. A maximum voltage of 770 kv was attained. Corona loss and radio influence (RI) performance were very satisfactory. Corona loss at the 500-kv operating level was negligible during fair weather. Correlation has been established between values of corona loss, RI, and audible sound measured simultaneously.
