Abstract
A capacitive voltage sensor assembly includes a first electrode extending along a longitudinal axis, a tubular section surrounding a portion of the first electrode and positioned radially outward from the longitudinal axis and the first electrode, the tubular section including an insulating layer, an inner conductive layer, and an outer conductive layer, and a mass of dielectric insulating material at least partially enclosing the first electrode and the tubular section. The mass of dielectric insulating material fills through openings formed in the tubular section.
Claims23
A voltage measuring assembly comprising:
- a source electrode extending along a longitudinal axis;
- a tubular section extending along the longitudinal axis and at least partially surrounding the source electrode such that the tubular section is radially spaced from the source electrode, the tubular section including:
- a plurality of sections located side by side in a circumferential manner around the longitudinal axis, wherein adjacent sections of the plurality of sections are spaced apart from each other on a circumference of the longitudinal axis, and wherein each section extends along the longitudinal axis;
- wherein each section includes a first portion including a first electrically conductive material and a second portion including a second electrically conductive material, wherein the first portion is located closer to the longitudinal axis than the second portion, wherein the first portion is configured to form a capacitive coupling with the source electrode, and wherein the second portion is configured to shield the capacitive coupling from external electric fields;
- and
- a mass of insulating material at least partially enclosing the source electrode and the tubular section;
- wherein each section includes a plurality of through openings that are configured to be filled by the insulating material, and wherein spaces between adjacent sections of the plurality of sections are filled by the insulating material.
