Claim Text:
1. A high voltage sensing unit, comprising: a housing including a horizontal portion and a vertical portion joined at an elbow, and an internal bore; a resistive voltage divider including a primary resistor and a secondary resistor configured in series mounted in the housing; a connecting assembly configured to attach the high voltage sensing unit to a terminal of a high voltage switching device, wherein the connecting assembly provides an electrical connection from the high voltage switching device to the primary resistor, and wherein the connecting assembly supports the high voltage sensing unit; and an interface cable providing an electrical connection from the secondary resistor to a receptacle on the high voltage switching device, wherein the horizontal portion supports the primary resistor within an insulating spacer, wherein the vertical portion supports a grounded shaft, within another insulating spacer, that leads to the secondary resistor, wherein the horizontal portion includes a horizontal shed sleeve with a plurality of fins extending radially from an exterior surface of the horizontal shed sleeve, wherein the vertical portion includes a vertical shed sleeve with another plurality of fins extending radially from an exterior surface of the vertical shed sleeve, wherein the horizontal shed sleeve is removably attached to the outside surface of the horizontal portion via an interference fit, and wherein the vertical shed sleeve is removably attached to the outside surface of the vertical portion via an interference fit.
