Desert measurements of corona loss

THIS ARTICLE reports corona-loss measurements under desert conditions on 1.25-inch and 1.4-inch Hedernheim (HH) copper conductor and 1.4-inch aluminum-cable steel-reinforced (ACSR) conductor. From studies which have been conducted at Stanford University^2,3 and subsequent theoretical analysis,⁴ it was indicated that 1.4-inch-diameter conductor would operate satisfactorily at 287 kv and that the segmental-type cable was more than sufficient for operation at 287 kv. This diameter initially had been established as a result of certain studies conducted on stranded-type cables.
