Project UHV is an attempt to study the possibility of higher than 600-kV dc transmission as an alternative or a complement to uhv ac transmission. The Lenox, Massachusetts facility will be used to study the near-field effects of dc testing at voltage levels up to about 750-kV bipolar and 1500-kV monopolar. The site will also provide data on the concurrent operation of both ac and dc lines in very close proximity. The new facilities added to Project UHV consist of an ac-dc converter station, a 577-ft dc test line, conductor test bay, an instrumentation trailer with additional ozone and weather monitoring equipment, and a midspan measurement area where ion current, dc electric field, conductor current, and audible corona are evaluated. Laboratory research to date indicates that corona-related effects, such as audible noise and radio interference, are less of a problem in the case of dc transmission. A group of 120 persons tested their perception of the effects of the dc field in fair weather. Additional test results are indicated for perceptions in rain or windy weather conditions. (MCW)
