Patent number: 11879927Abstract: A system and method for determining if a fault condition exists in an electrical network. The method includes determining that a fault protection device has been opened and monitoring a voltage angle of a voltage waveform across a vacuum gap switching arrangement if the fault protection device is open, where the vacuum gap switching arrangement includes at least one vacuum gap switching element. The method also includes triggering a breakdown of a vacuum gap in the at least one vacuum gap switching element when the voltage angle corresponds to a predetermined switching angle to enable a temporary current flow through the vacuum gap switching arrangement, measuring the current flow through the vacuum gap switching arrangement, and determining whether the fault condition exists based at least in part on the measured current flow.Type: GrantFiled: December 17, 2019Date of Patent: January 23, 2024Assignee: S&C Electric CompanyInventors: Goran Djogo, Michael Ennis

Publication number: 20060237444Abstract: A current sensor for installation on a conductor without breaking the conductor may include an insulating base having a conductor supporting portion and a conductive coil disposed within an outer surface of the insulating base. A magnetically permeable conductor retaining member includes a portion that passes through the coil and is secured to the insulating base. The retaining member defines a conductor receiving aperture portion with the aperture portion being disposed adjacent the conductor supporting portion of the insulating base. With a conductor positioned within the aperture portion, the conductor is secured by the retaining member to the conductor receiving portion of the insulating base and a substantially continuous permeable path is formed by the conductor retaining member about the conductor.Type: ApplicationFiled: February 1, 2006Publication date: October 26, 2006Inventors: Michael Ennis, Thomas Tobin

Publication number: 20050212524Abstract: An arrangement and method is provided for determining the present condition and/or expected life of electric power lines via the measurement and analysis of the current into and the current out of the electric power line, thus permitting preventive action on electric power lines before problems arise. In this way, any departure from normal operation may also be detected, e.g. such as caused by a high-impedance fault or the like. The phase angle difference between the input and output currents provides a measure of the condition of the line, i.e. specifically, this phase angle shift between the input and output currents increases as the line ages and loss factors increase. Due to the inherent noise in the current signals, in one embodiment the phase angle shift is measured via a cross-correlation between the input and output current signals to provide the measured phase angle.Type: ApplicationFiled: November 30, 2004Publication date: September 29, 2005Inventors: Michael Ennis, Debashis Satpathi
