1. A capacitive voltage sensor assembly comprising:
an electrode extending along a longitudinal axis;
a tubular section extending along the longitudinal axis and at least partially surrounding the electrode such that the tubular section is radially spaced from the electrode, the tubular section including
a first layer made of an electrically insulating material, the first layer having a first plurality of through openings comprising a first row of circumferentially spaced through openings and a second row of circumferentially spaced through openings and each through opening of the first row is aligned with a through opening of the second row in a direction parallel to the longitudinal axis,
a second layer made of an electrically conductive material disposed on an inner surface of the first layer, the second layer having a second plurality of through openings comprising a first row of circumferentially spaced through openings and a second row of circumferentially spaced through openings and each through opening of the first row is aligned with a through opening of the second row in a direction parallel to the longitudinal axis, and
a third layer made of an of electrically conductive material disposed on an outer surface of the first layer, the third layer having a third plurality of through openings comprising a first row of circumferentially spaced through openings and a second row of circumferentially spaced through holes and each through opening of the first row is aligned with a through opening of the second row in a direction parallel to the longitudinal axis; and
a mass of dielectric material at least partially enclosing the electrode and the tubular section, wherein the mass of dielectric insulating material fills through openings in the tubular section,
wherein each through opening of the second plurality of through openings is circumferentially aligned with a through opening of the third plurality of through openings.
