An eight-year investigation of lightning currents and preventive lightning protection on a transmission system

E. C. Starr (Oregon State College, Corvallis, Oreg.): Mr. Hansson and Mr. Waldorf have made a further addition to the growing fund of information on lightning currents, and they have made a careful analysis of the results of preventive lightning protection as practiced on their system. Additional useful information can be obtained from the data they have presented and from other relative data probably available in their files.
