Abstract

A theoretical approach to partial discharge transients is presented. This approach is based on the relationship between the charge induced on the measurement electrode by those created in the interelectrode volume during partial discharge activity. The primary sources for these induced charges are the charges which, as a result of partial discharge activity, are distributed within the voids of the insulation medium. These charge relationships are derived, and their application to the measured transients associated with the time dependence of the induced charge is presented. The application to multiple electrode systems of practical interest is illustrated. A discussion of the salient features and practical aspects of the theory is included
