Abstract

Measured data are presented on electric field strengths near ground level under 765 kV and 510 kV single circuit and 345 kV double circuit overhead power transmission lines, values of short circuit current originating on vehicles situated in relatively intense electric fields, and estimates of perception and annoyance for humans resulting from transient spark discharge. Calculated data are given for the electric field strength beneath 765 kV single circuit, 500 kV single circuit, and 345 kV single and double circuit lines.
