Lightning investigation on a 220-kv system — III

LIGHTNING research has been conducted for the past 13 years^1–6 by the Pennsylvania Power and Light Company, the General Electric Company, and the Ebasco Services, Inc., chiefly upon that portion of the Pennsylvania-New Jersey 220-kv interconnection circuit between Wallenpaupack and Siegfried, Pa. This 65-mile-long circuit is of aluminum-conductor steel-reinforced three-conductor horizontal-configuration steel-tower construction, having originally 14-unit insulation. Since 1932 the 28-mile section from Wallenpaupack to Bushkill has been called the Wallenpaupack tap, and the remainder constitutes part of the Siegfried-Roseland line.
