Patent number: 9698571Abstract: An improved triggered arc flash arrester includes a shield apparatus disposed within an interior of an evacuated envelope and includes a first shield element and a second shield element. A plurality of conductors are partially disposed within the interior and are separated from one another by a gap. A first element of the shield apparatus is situated adjacent the envelope and is structured to protect the envelope from damage due to the high temperature plasma that results from an arc across the gap. A second element of the shield apparatus is interposed between the gap and at least a portion of the first element and is structured to protect the at least portion of the first element from damage due to an arc across the gap.Type: GrantFiled: May 4, 2015Date of Patent: July 4, 2017Assignee: EATON CORPORATIONInventors: John Joseph Shea, Ganesh K.

Patent number: 9638738Abstract: An apparatus is for a power circuit providing an alternating current to a load. The apparatus includes a high frequency current sensor structured to cooperate with the power circuit to provide a high frequency current signal. A voltage zero crossing detector is structured to cooperate with the power circuit to provide a voltage zero crossing signal. A high pass filter is structured to provide a filtered current signal from the high frequency current signal. A threshold comparator is structured to provide an output when the filtered current signal exceeds a predetermined value. A processor is structured to receive the voltage zero crossing signal and the output of the threshold comparator and output a trip signal in response to undesired series arcing by detecting an unsymmetrical high frequency signal for a predetermined number of cycles.Type: GrantFiled: March 13, 2013Date of Patent: May 2, 2017Assignee: EATON CORPORATIONInventor: John Joseph Shea

Patent number: 9530033Abstract: A wireless transponder unit having a maximum operating temperature and being structured to be disposed on an electrical joint includes: an integrated circuit configured to store identification information; and a resonant circuit electrically connected to the integrated circuit, the resonant circuit having a damping factor. The resonant circuit includes a capacitor, an antenna, and a resistor having a resistance and a positive thermal coefficient. A change in temperature of the wireless transponder unit causes a change in the resistance of the resistor and the damping factor of the resonant circuit. The maximum operating temperature of the wireless transponder unit is based on the damping factor of the resonant circuit.Type: GrantFiled: May 28, 2013Date of Patent: December 27, 2016Assignee: Eaton CorporationInventors: John Joseph Shea, Jason B.
