Abstract
A sensor assembly includes a connecting bar extending along a longitudinal axis and a tubular body extending along the longitudinal axis and at least partially surrounding the connecting bar such that the tubular body is radially spaced from the connecting bar. The tubular body includes a support member made of insulating material. The tubular body also includes a first section with an electric field sensor comprising a first layer of electrically conductive material on an inner surface of the support member to detect an electric field produced by the connecting bar. The first section also includes a first electric screen comprising a second layer of electrically conductive material on an outer surface of the support member to shield the electric field sensor from outside electrical interference. A second section disposed adjacent the first section includes a second electric screen. A dielectric material at least partially encloses the tubular body.
