  • Abstract
    An investigation was made in order to develop a location technique of corona discharge in insulating oil, in view of the development of the UHV transformer. This paper describes the principle of analyzing the corona location by making use of electrostatic probes. The corona produces a space charge in the oil, and induces charges on the probes electrostatically. Thus, the location as well as the space charge of the corona can be analyzed.
