Patent number: 10992126Abstract: A method involves a circuit interrupter installation having a circuit interrupter with a plurality of poles and an ETU electrically connected with a neutral current sensor situated in proximity to a neutral conductor. The method includes determining that a plurality of fundamental frequency phase current vectors, when summed, are substantially equal to a fundamental frequency neutral current vector, and/or that a plurality of triplen odd-numbered harmonic phase current vectors, when summed, are substantially equal to a triplen odd-numbered harmonic neutral current vector. Responsive to the determining, the method includes outputting a notification which represents a possibility that a neutral current detection apparatus is mis-wired, and/or employing with the ETU a reverse vector that is an opposite of the fundamental frequency neutral current vector in the ongoing monitoring for an event that would trigger the movement of the circuit interrupter from the ON condition to the OFF or TRIPPED condition.Type: GrantFiled: November 16, 2018Date of Patent: April 27, 2021Assignee: EATON INTELLIGENT POWER LIMITEDInventors: Paul R.

Publication number: 20170047184Abstract: A component monitoring system structured to monitor circuit breaker assembly component characteristics is provided. The component monitoring system includes a record assembly, a number of sensor assemblies, a comparison assembly, and an output assembly. The record assembly includes selected nominal data for a selected circuit breaker component. The sensor assembly is structured to measure a number of actual component characteristics of a selected circuit breaker component and to transmit actual component characteristic output data. The comparison assembly is structured to receive an electronic signal from said record assembly and said sensor assemblies, to compare said sensor assembly actual component characteristic output data to said selected nominal data and to provide an indication signal as to whether said sensor assembly output data is acceptable when compared to the selected nominal data. The output assembly includes a communication assembly and an output device.Type: ApplicationFiled: August 13, 2015Publication date: February 16, 2017Applicant: EATON CORPORATIONInventors: Koustubh Dnyandeo Ashtekar, James Jeffery Benke, Jiong Chen, Li Yu, Fangji Wu, Ronald Dale Hartzel

Publication number: 20080179967Abstract: An transfer switch having a transfer control provides electric power to a load. The transfer switch includes a power switching device provided with electric power from a first power source, such as a utility power source, and a second power source, such as a generator power source. The transfer control is structured to monitor the second power source, maintain a runtime count of the second power source, and provide an indication of the runtime count, either at the transfer switch or at a location remote from the transfer switch and the second power source.Type: ApplicationFiled: January 26, 2007Publication date: July 31, 2008Inventors: Todd Matthew Lathrop, Ronald Dale Hartzel, Bert Popovich

Patent number: 7368674Abstract: A stop device for an electrical device cell includes a generally flat, rectangular stop member and a generally flat, elongated permissive member. The stop member is, preferably, part of a stop member assembly that includes a biasing device. The cell includes a pair of rails upon which a drawout electrical device is movably disposed. The stop member is disposed adjacent to at least one housing assembly rail and is structured to move between a first, extended position, wherein the stop member engages the drawout electrical device and prevents the drawout electrical device from moving from the first, installed position to the second, drawn out position, and a second, withdrawn position, wherein the stop member does not engage the drawout electrical device and the drawout electrical device may move from the first, installed position to the second, drawn out position.Type: GrantFiled: September 29, 2006Date of Patent: May 6, 2008Assignee: Eaton CorporationInventors: Paul Kimball Parker, Ronald Dale Hartzel, James Edward Smith, Paul Anthony Colbaugh, Ronald Alan Carder, Marcy Dawn Scialabba

Patent number: 6590481Abstract: An electrically powered, fast acting transfer switch utilizes a single action solenoid that, alternately, through a mechanical assembly, moves the handle of one electric power switch between OFF and ON positions. A coupling including a rigid strap operates the handle of a second electric power switch oppositely between ON and OFF positions. The mechanical assembly includes an electromagnet drive plate to which the electromagnet of the solenoid is secured and an armature drive plate carrying the solenoid armature. A latch mechanism alternately holds one drive plate and then the other stationary so that the electromagnet and armature alternately move to effect reciprocal movement of the handle of the one electric power switch, and through the rigid strap, the handle of the second electric power switch.Type: GrantFiled: December 28, 2000Date of Patent: July 8, 2003Assignee: Eaton CorporationInventors: David Curtis Turner, Jeffrey Lowell Woods, David Michael Olszewski, William Ellsworth Beatty, Jr., Ronald Dale Hartzel

Patent number: 5907461Abstract: A molded case circuit breaker is provided with ground fault protection by a modular unit which drops into a pole compartment in the molded casing in place of a pole assembly. The modular unit includes a housing forming an open faced cavity across which is mounted a printed circuit board with the ground fault circuit components and trip solenoid projecting into the cavity. The housing also supports the ground fault sensing toroid in a position for the appropriate conductors to pass through the coil. A bell switch and auxiliary switch are positioned by the housing for actuation by levers mounted on the cradle pin and crossbar, respectively. An integral leaf spring molded into the housing accommodates for manufacturing tolerances and fixes the positions of the various components.Type: GrantFiled: October 1, 1997Date of Patent: May 25, 1999Assignee: Eaton CorporationInventors: Ronald Dale Hartzel, Keith Lynn Mayhood, William David Munsch, John Joseph Kurtz, Richard Edwin White
