Abstract
Economic considerations often limit the use of full-scale 3-phase test lines for the investigation of transmission-line corona effects. Testing of a large number of different conductor configurations can be more conveniently and efficiently carried out on comparatively short sections of conductors on single-phase test lines and in test cages. Techniques for measuring the single-phase corona performance of conductors are presented, along with a discussion of means by which the observed data can be used to determine the corona performance of 3-phase transmission lines.
