The essentials of a corona test on insulating materials include a suitable method of detecting and measuring the corona produced. Such a method should be as simple as possible, yet be sensitive to the corona produced. At the same time it should have minimum susceptibility to interfering, extraneous signals. These requirements are not completely compatible so a compromise is usually resorted to for each particular set of test conditions. However, there are certain basic concepts of corona detection and measurement which can serve as a guide in selecting the best compromise. It is the purpose of this paper to present some of these concepts and to indicate their application under commonly-encountered test conditions.
