Power relationships and temperature dependence in the D-C corona field

The study of d-c corona discharge over a period of many years has resulted in a considerable body of literature on the subject. However, relatively little has been reported on corona properties over extended temperature ranges. At least two experimental studies have been published, both using coaxial cylindrical geometry. The first, by Koller and Fremont,1 treats negative corona at temperatures to 1,400 R (degrees Rankin) and pressures to 5 atmospheres. The second, by Thomas and Wong,2 treats both positive and negative corona at temperatures to 2,000 R and pressures to 8 atmospheres.
