A field study of the short-line-fault component of transient recovery voltage

Abstract
The short-line-fault transient recovery voltage component is a critical factor in arc interruption. This paper is a study of 345kV field data, generated by a pulse test circuit, which develops inherent characteristics for the "bare" line. The modifying effects of terminal equipment on the shape of the saw-tooth component are demonstrated experimentally and theoretically. Test results are compared with present ANSI Standard requirements to verify the application.
