Publication number: 20240295622Abstract: A system for monitoring a voltage of a conductor of an electric power delivery system after automatic voltage sensor calibration. The system includes a sensor for capacitive coupling with an access point. The system includes an IED in electrical communication with the sensor to obtain signals therefrom. The IED may be configured to automatically calibrate to accommodate the signals from the conductor obtained using the sensor. The IED may provide an output depending on the determined voltage on the conductor.Type: ApplicationFiled: November 2, 2023Publication date: September 5, 2024Applicant: Schweitzer Engineering Laboratories, Inc.Inventors: Henry Loehner, Naiden K. Spasov, Stephen F. Witt, Miralem Cosic, Jeff Bassett, Anatoliy V. Kozlov, Kenneth J. Van Den Heuvel

Patent number: 10379500Abstract: Systems and methods for detecting the failure of a precision time source using an independent time source are disclosed. Additionally, detecting the failure of a GNSS based precision time source based on a calculated location of a GNSS receiver is disclosed. Moreover, the system may be further configured to distribute a time derived from the precision time source as a precision time reference to time dependent devices. In the event of a failure of the precision time source, the system may be configured to distribute a time derived from a second precision time source as the precision time signal during a holdover period.Type: GrantFiled: August 22, 2017Date of Patent: August 13, 2019Assignee: Schweitzer Engineering Laboratories, Inc.Inventors: Shankar V. Achanta, David E. Whitehead, Henry Loehner
