Patent number: 9696348Abstract: Multi-layer capacitor divider voltage sensors include a plurality of voltage sensor conductive layers having sensor to ground interface surfaces. Respective voltage sensor conductive layers are connected to each other and sensor output voltage Vs by continuations of material forming the interface surfaces extending therebetween. The voltage sensors also include a plurality of conductive ground layers connected to electrical ground, the ground layers interleaved with the voltage sensor conductive layers so that a conductive ground layer resides between adjacent conductive voltage sensor layers. A first voltage sensor conductive layer (closest to a line conductor) is electrically connected to the other conductive voltage sensor layers and output voltage Vs and has a sensor to conductor interface surface with a corresponding interface area.Type: GrantFiled: May 19, 2016Date of Patent: July 4, 2017Assignee: Eaton CorporationInventors: Mark Allan Juds, Kurt von Eckroth, John Trublowski, Naresh Kumar Kodela

Publication number: 20090059463Abstract: A multi-value capacitor with a safety disconnect mechanism has a capacitive element with six capacitive sections, a common wire, and six section wires enclosed in a cylindrical metal can with a metal lid that normally has a concave configuration. The wires are soldered to contacts extending through the concave metal lid. The safety disconnect mechanism includes an external insulator disk with terminals. The terminals in the insulator disk align with the contacts in the metal lid. The center common terminal of the insulator disk is fixedly riveted to the center common contact of the metal lid. Spring elements form the electrical connection between the section terminals of the insulator disk and the section contacts in the metal lid.Type: ApplicationFiled: July 15, 2008Publication date: March 5, 2009Inventor: Charles Barry Ward
