The broad aspects of an approach to corona testing of components are presented. These involve selection of a testing system consistent with the electrical properties of the component, comparison of results with expected voltage levels in service, interpretation of corona indications, elimination of corona where necessary, and accelerated life testing for establishment or confirmation of relationships between corona observations and life. Examples are given. Observations and interpretation of corona do not provide a cure-all for dielectric problems but they are useful tools in solving many problems.
