Abstract :
D. D. MacCarthy (General Electric Company, Pittsfield, Mass.): Messrs. Bergvall and Beck have presented an informative discussion of the division of long-duration lightning currents between arresters and the transformers connected to grounded-neutral circuits. This analysis confirms the prediction made by Doctor K. B. McEachron1 in February 1939 when he discussed some of the long-time discharges which he recorded oscillographically as early as 1937. In this article Doctor McEachron states, regarding continuing lightning discharges to grounded neutral systems: … the transformer winding represents a relatively small impedance to the flow of such unidirectional currents.
