An Examination of Electric Fields Under EHV Overhead Power Transmission Lines.

摘要

The report contains measured data on electric field strengths near ground level under 765kV and 510kV single circuit and 345kV 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 is given for the electric field strength beneath 765kV single circuit, 500kV single circuit,and 345kV single and double circuit lines.
