Body Currents in Live Line Working

Abstract
A series of tests have been conducted at 138 and 345 kV to determine field intensities and body currents to which live line transmission linemen are subjected in various methods of working. These tests confirm that field intensities and body currents encountered in present practices, for the methods and voltages of the tests, are well below the threshold of feeling and perception. With still higher voltages, body currents can be maintained at acceptably low levels by means of adequate shielding, for any method of working.
