The Klydonograph and Its Application to Surge Investigation

Abstract
In the past few years the need of a device for recording voltage surges on transmission lines has been felt more and more. Realizing this need, J. F. Peters, in the fall of nineteen twenty-three, developed the klydonograph which utilizes the Litchtenberg figure to record the characteristics of transient voltages. The principle of the instrument and practical connections to a line are discussed. The results obtained in the field from four investigations are given. Parts II and IV describe the first experimental model of the klydonograph which uses a stationary glass photographic plate in removable plateholders with a moving electrode, and the commercial type of klydonograph which uses a day-light loading roll film of sufficient length to last seven days. This latter model has three electrodes for connection to a three-phase line.
