Phase-to-Phase Switching Surges on Line Energization

Abstract

Data from an investigation of a miniature system are given on the magnitude and wave shape of phase-to-phase switching surges produced upon energization of a transformer-terminated line. The effects of line length, terminating impedances, and switching conditions are included. This information is needed for the evaluation of phase-to-phase clearances and insulation, since there appears to be little, if any, information published on the matter.
