Field measurements and calculations of electrostatic effects of overhead transmission lines

Abstract

The results of an electrostatic measurements program held in conjunction with the IEEE Working Group on E/S and E/M Effects of Transmission Lines and attended by representatives of several organizations are presented. Measurements were made at ground level under an energized 525-kV line of electric field intensity, of induced currents and voltages on objects, and of perception and annoyance levels of men, women, and children for steady state and transient shocks. Three types of field strength meter were employed. They gave consistent readings in agreement with predicted field strength. Analytical estimates of short circuit current for various objects are in agreement with measured values.
