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… 
Klydonograph Surge Investigations
Since its recent development, the klydonograph has been used to investigate surge conditions on a number of transmission systems. Quantitative data, which show the characteristics of the actual
The measurement of surge voltages on transmission lines due to lightning
This paper, after referring to the work of previous investigators in the application of the photographic Lichtenberg figures to the measurement of surge voltages, describes results of additional work

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
Measurement of transients by the lichtenberg figures
The paper gives the results of a comprehensive study of the effect of transients on the size and appearance of Lichtenberg figures. Sixteen different rates of voltage rise were used, varying from

Data on the surge voltage investigation, carried out under the auspices of the Subcommittee on Lightning, on one of the 132-kv. lines of the American Gas and Electric Company during 1928, are
Lightning Peak Current Sensor Based on Electret Technology
Lightning peak current is one of the most important parameter concerning the studies of the lightning phenomena. Nowadays, with a continuous dissemination of elevated structures, such as
The Influence of Polarity on High-Voltage Discharges
An experimental investigation of the influence of polarity on high-voltage discharges is reported in this paper. Particular attention is given to those discharges used in high-voltage measurements. A
Direct Measurement of Surge Currents
A study of the behavior of 2 magnetic links under the influence of oscillatory surge currents has made this instrument useful in measuring the per cent oscillation as well as crest values of surge currents.
Vacuum Switching Experiments at California Institute of Technology
Successful experiments in switching or breaking a circuit in a high vacuum have been made at the California Institute of Technology. This paper is a report on three sets of these experiments, which
