Abstract

See full text

A capacitive network for use in a voltage sensor includes a first conductor shaped to form a boundary that separates a first interior space and a first exterior space; a second conductor shaped to form a boundary that encircles a second interior space and separates the second interior space from a second exterior space; a third conductor disposed in the second interior space and having a line of sight to the first conductor through an opening in the second conductor; and an external insulator formed around the first conductor and the second conductor in the first exterior space and the second exterior space. A first capacitance is formed between the first conductor and the third conductor, a second capacitance is formed between the second conductor and the third conductor, and conductive material that may collect on the external insulator has negligible effect on the first capacitance and the second capacitance.
