Patent number: 11165237Abstract: An arc fault detection system samples a high frequency signal on a power line sequentially at different frequency regions according to a frequency hopping sequence, which is repeated a number of times over a predefined period. The different frequency regions include at least one region with a carrier for power line communication on the power line and at least one region without a carrier for power line communication on the power line. The system obtains energy measurements for each frequency region based on the sampled signals, computes an energy level for each frequency region based on the measurements for each region, and assigns a binary value to each region according to the corresponding energy level. The binary value represents a presence or absence of signal content in the frequency region. The system determines a presence or absence of an arc fault based on the binary values for the frequency regions.Type: GrantFiled: February 12, 2020Date of Patent: November 2, 2021Assignee: Schneider Electric USA, Inc.Inventors: Andi Jakupi, Michel Layour, Hynek Raisigel, Costin Vasile, Paul A.

Patent number: 10181714Abstract: The disclosed methods and systems employ a nonprobability-based detection scheme that measures conditions (e.g., voltage or current) at multiple locations on a circuit, such as a branch circuit, to detect for a presence of an arc fault condition. A centralized processing system, such as a controller (120), receives information corresponding to a branch origin voltage or current measurement sensed by a sensor (114, 116) at a branch origin upstream of the plurality of end-use devices (150) on the branch circuit (e.g. at a circuit breaker defining the branch), and receives information corresponding to a downstream voltage or current measurement at each of the end-use devices sensed by a corresponding downstream sensor (152, 154).Type: GrantFiled: September 30, 2013Date of Patent: January 15, 2019Assignee: SCHNEIDER ELECTRIC USA, INC.Inventors: Jeremy D.

Patent number: 10114057Abstract: A system and method to detect arc faults in branch wiring. The system includes a line conductor and a neutral conductor. A circuit breaker is connected to an alternating current source via the line and neutral conductors. Electrical outlet devices are coupled to the circuit breaker via the line and neutral conductors. Each of the electrical outlet devices has a neutral shorting switching element coupled between the line and neutral conductors, and a load control switching element in the line conductor. The electrical outlet devices also each include an outlet controller to control the switching elements. The outlet controllers close the neutral shorting switching elements and the master controller determines if high impedance is present to detect a series arc fault. The outlet controllers open the load control switching elements and the master controller determines if any current is flowing on the line conductor to detect a parallel arc fault.Type: GrantFiled: June 21, 2013Date of Patent: October 30, 2018Assignee: Schneider Electric USA, Inc.Inventors: Joseph Beierschmitt, Jeremy Schroeder

Patent number: 10084304Abstract: An arc fault circuit interrupter (AFCI) outlet is disclosed which detects and interrupts upstream parallel arc faults. The example AFCI outlet includes a switching element coupled between the line and neutral conductors at the outlet. The outlet also includes a voltage sensor and a current sensor. A parallel upstream arc fault is detected from a sensed voltage drop and no corresponding increase in current. On detecting the arc fault, the switching element is closed and current flows through the relatively lower resistance switching element interrupting power through the arc fault. The closed switching element results in an overcurrent condition causing an upstream conventional thermal-magnetic circuit breaker to trip.Type: GrantFiled: July 1, 2013Date of Patent: September 25, 2018Assignee: Schneider Electric USA, Inc.Inventors: Joseph Beierschmitt, Jeremy Schroeder

Patent number: 8503148Abstract: An electronic circuit breaker includes controllable contacts adapted to connect a power source to at least one load, and a microcontroller for monitoring the flow of power to the load, detecting different types of fault conditions and automatically opening the contacts in response to a fault. A primary power supply of the breaker receives power from the line source when the contacts are closed, and supplies power to the control circuitry. Fault indicators in the microcontroller indicate the type of fault that caused the contacts to open. A secondary power supply provides power to the control circuitry when the contacts are open and a switch is closed.Type: GrantFiled: October 20, 2010Date of Patent: August 6, 2013Assignee: Schneider Electric USA, Inc.Inventors: Jeremy D.
