Transmission line voltage surges

Records of the transients actually occurring on transmission lines of widely varying characteristics have been obtained recently with the klydonograph. 1. These records substantiate many of the theories of transients on lines. 2. They indicate the incorrectness or incompleteness of some of hese theories. 3. They suggested modifications or extensions of these latter theories. This paper is a coordination of those theories which agree with test data obtained up to the present time. Since the results of the klydonograph surge investigations are presented in a companion paper, only the data required to make this paper complete in itself are included.
