1. A capacitive voltage sensor assembly comprising:
a source electrode extending along a longitudinal axis;
a tubular shield surrounding and spaced in a direction radially outward from the longitudinal axis and from a portion of the source electrode, wherein the tubular shield includes a plurality of through holes; and
a circular sensor element positioned radially inward of the tubular shield and including a first layer of electrically conductive material and a second layer of electrically insulating material, wherein the circular sensor element surrounds and is spaced in a direction radially outward from the longitudinal axis and from a portion of the source electrode, and wherein the circular sensor element includes a plurality of through holes each configured as an elongated slit having an axial length extending in a direction parallel to the longitudinal axis.
