Detection of Corona Discharges in Lumped Circuit Specimens

In tests carried out on lumped capacitance specimens, the assumption is made that the apparent corona pulse charge is given by the product of the capacitance of the specimen and the resultant change in voltage across the terminals of the specimen. It is the intent of this chapter to examine the factors that are involved in the precision of this relationship as well as the possible significance of the measured apparent charge with the prospective life of the lumped capacitance specimen. Recommendations are also to be made relative to the means available to improve the significance of the apparent charge measurements.
