Publication number: 20250199035Abstract: A multiport current sensor is disclosed for measuring current. The sensor may include multiple CT or Rogowski coil segments or sections arranged in a closed loop configuration around a monitored phase line or other electrical conductor. An adjacent phase rejection circuit compares the magnitudes and/or phase angles of the voltage signals from the multiple coil segments. The adjacent phase rejection circuit may detect if a fault in an adjacent phase line or other electrical conductor is affecting the output signal of the current sensor by more than a threshold amount. The adjacent phase rejection circuit may additionally or alternatively indicate whether the measured values are valid for detecting a fault on the monitored phase line or other electrical conductor.Type: ApplicationFiled: April 2, 2024Publication date: June 19, 2025Applicant: Schweitzer Engineering Laboratories, Inc.Inventors: Johnny J. Moore, David Kenny, Raymond W. Rice, Miralem Cosic, Lyssa W. Blood

Publication number: 20240312688Abstract: A current transformer (CT) isolation clamp is mounted to a phase conductor and includes a step-down CT transformer and a passive isolation transformer. A three-phase power-harvesting sensor system includes a plurality of CT isolation clamps mounted to phase conductors in a three-phase power system. An electronics module is connected to the CT isolation clamps. The electronics module may include a sensing circuit to determine power characteristics of the three-phase power system based on the outputs of the CT isolation clamps. The electronics module may include a communication subsystem to transmit the determined power characteristics to local or remote devices. Additionally, the electronics module may include a power harvesting circuit to harvest power to operate the sensing circuit and the communication subsystem.Type: ApplicationFiled: March 14, 2023Publication date: September 19, 2024Applicant: Schweitzer Engineering Laboratories, Inc.Inventors: Timothy M.

Publication number: 20240153700Abstract: Systems and methods include using a magnetic core winder to install a powerline-mounted device with a non-gapped magnetic core, therefore reducing the weight of the powerline-mounted device while still harvesting equal or more power than a large cross-sectional and gapped magnetic cores. In particular, the methods include installing bobbin(s) and a core housing on a powerline and winding strip/ribbon core material onto the core housing. The bobbins may be wound axially opposed to on a toroid winder, which improves the accuracy of turns count of the magnetic core. The improved accuracy of turns count may increase the accuracy and/or tolerance of magnetic component(s) of the powerline-mounted device.Type: ApplicationFiled: November 3, 2022Publication date: May 9, 2024Applicant: Schweitzer Engineering Laboratories, Inc.Inventors: David Kenny, Brett Taggart, Timothy M.

Patent number: 11961656Abstract: A current transformer includes a pre-formed core forming a closed loop with a flexible axially wound secondary winding. A continuous length of wire is axially coiled around a flexible bobbin to form a secondary winding. The resulting secondary winding may be slid onto the closed loop of the pre-formed core. The flexibility of the axially wound secondary winding facilitates conformity to a non-linear shape of the pre-formed core.Type: GrantFiled: August 12, 2020Date of Patent: April 16, 2024Assignee: Schweitzer Engineering Laboratories, Inc.Inventors: Timothy M.

Patent number: 11152152Abstract: The present disclosure relates to a fabrication process for a current transformer. For example, the process may include wrapping first windings around a first core half of a magnetic core of a current transformer. The process may include wrapping second windings around a second core half of the magnetic core. The magnetic core may be inserted into an overmold tool. The process may include overmolding a first overmold over the first core half of the magnetic core and a second overmold over the second core half of the magnetic core. After overmolding, the magnetic core may be cut in half.Type: GrantFiled: December 3, 2018Date of Patent: October 19, 2021Assignee: Schweitzer Engineering Laboratories, Inc.Inventors: Mark A.

Patent number: 11031812Abstract: The present disclosure relates to powering distributed sensors used to monitor electrical and/or environmental conditions and to powering other equipment associated with electric power systems. In one embodiment, a system may be used to mount a sensor in proximity to a reference conductor. An electric field power conversion subsystem may generate a usable electric potential from an electric field created by the electric power system and existing between the reference conductor and another conductor (e.g., another phase conductor, a ground conductor). The sensor powered by the usable electric potential may provide a measurement of a condition associated with the electric power system. A communication subsystem powered by the usable electric potential may communicate the measurement of the condition to a monitoring system.Type: GrantFiled: January 8, 2021Date of Patent: June 8, 2021Assignee: Schweitzer Engineering Laboratories, Inc.Inventors: Edmund O.

Publication number: 20050283096Abstract: An apparatus and method for detecting swallowing activity is provided. In an embodiment, a method includes receiving an electronic signal from an accelerometer that represents swallowing activity, extracting at least two features from the signal, classifying the signal as a type of swallowing activity based on the extracted features, and generating an output of the classification. Exemplary activities include swallows, aspirations, movement and vocal artifacts. By indicating whether an activity is a swallow or an aspiration, the manner in which a patient afflicted with an increased likelihood for aspirations is fed can be adjusted to increase the likelihood of achieving a swallow instead of an aspiration during feeding. In turn this could reduce hospitalizations for aspiration pneumonia in patients with acute or chronic injury.Type: ApplicationFiled: June 17, 2004Publication date: December 22, 2005Applicant: Bloorview MacMillan Children's Centre, a corp. registered under the Ontario Corporations ActInventors: Thomas Chau, David Kenny, Michael Casas, Glenn Berall
