From design, production, marketing and end-use points of view it is important that the corona problem, as it relates to electrical devices, be fairly well understood. The object here has been to focus on the four most significant phases of the problem. The principles of the ionization process and stress control are well documented in the literature. Detection-sensitivity requirements, and the corona...
The thought has been expressed that the manufacturer and user of insulating materials, who may use electrical resistance measured in accordance with ASTM D-257(1) as one means of evaluation and control, may not be familiar with the d-c tests that these materials are subjected to after assembly into insulation systems in apparatus. One of the purposes of this paper is to review d-c tests as they are...
The present requirements for establishing standard corona tests may be divided essentially into the following categories: 1. To establish a realistic test procedure for differentiating relatively among electrical insulating materials with regard to their ability to resist the direct action and by products of corona. 2. To establish standard corona measuring and calibrating circuits and to define the...
