Patent number: 11646681Abstract: Techniques for monitoring the health of a three-phase induction motor are provided. An expected threshold value is calculated as a function of an expected ratio of current unbalance to voltage unbalance for the three-phase motor. Embodiments determine whether a measured current unbalance exceeds the expected threshold value. Responsive to the measured current unbalance exceeding the expected threshold value, a remedial action may be taken, such as generating diagnostic information or activating one or more protection operations for the three-phase induction motor.Type: GrantFiled: August 22, 2022Date of Patent: May 9, 2023Assignee: Schneider Electric USA, Inc.Inventors: Kevin M.

Publication number: 20220396168Abstract: A method, apparatus and computer program product resolve the problem of unbalanced loads in an EVSE cluster of multiple EVSE charging stations. A signal is provided to the EVSEs identifying which phase of the three-phase power source has the highest current. When one of the EVSEs in the cluster determines whether it is connected to an EV's on board charging device, determines whether it is already charging the connected EV, and determines whether the EVSE is using the phase that has the highest current, then the EVSE may transmit a cluster load balancing control signal as a control pilot signal to the EV's onboard charging device to adjust the charging rate of the current that the EV is consuming from the EVSE.Type: ApplicationFiled: August 22, 2022Publication date: December 15, 2022Applicant: Schneider Electric USA, Inc.Inventors: Kevin M. JEFFERIES, Benjamin W. EDWARDS, Matthew L. White, Konstantin A. FILIPPENKO, Richard K. WEILER

Patent number: 11366142Abstract: A measurement module receives crosstalk compensation factors that include distance factors based on respective distances of a current sensor of the module from respective current sensors of other measurement modules and phase difference factors based on respective differences between the phase of a source current measured by the module and respective phases of source currents measured by the other modules. The module monitors messages reporting current measurements transmitted from the other modules connected to a broadcast bus, of current measurements made by respective current sensors of the other modules measuring other respective source currents. The module determines a reported current that is computed as a function of current measurement by the module's current sensor, reported current measurements monitored from the other modules, and the received crosstalk compensation factors. The module transmits the determined reported current over the broadcast bus to the other modules and a central controller.Type: GrantFiled: November 22, 2019Date of Patent: June 21, 2022Assignee: Schneider Electric USA, Inc.Inventors: Kevin M.

Patent number: 11333690Abstract: A measurement module uses harmonic compensation factors to minimize the effects of harmonic distortion in measurements of a source current by a current sensor of the module. The module samples at a first sampling rate, measurements of the source current to generate a first current measurement. The module samples at a second sampling rate higher than the first sampling rate, for an interval of time, measurements of the source current to generate a second current measurement. The module determines a harmonic compensation factor based, at least, on a difference between the first current measurement and the second current measurement. The module determines a reported current computed as a function of at least the first current measurement, the difference between the first current measurement and the second current measurement, and the harmonic compensation factor. The reported current represents a magnitude of the source current adjusted by the harmonic compensation factor.Type: GrantFiled: December 16, 2019Date of Patent: May 17, 2022Assignee: Schneider Electric USA, Inc.Inventors: Kevin M.

Publication number: 20210119441Abstract: A progressive protection method automatically adapts a protection trip delay or fault timeout for a motor that is a member of a group of motors performing mutually similar or related tasks, based on the occurrence of a fault in another motor within the group, without requiring manual intervention. If the user requires stringent protection of the motors in a particular application, then the trip delay time for all of the motors in the group, may be shortened in response to recently-detected similar trips of other motors within the group. Alternatively, if the user prefers continuity of service for a particular application, then the trip delay time for all of the motors in the group, may be increased in response to recently-detected similar trips of other motors within the group, based on past experience with the occurrence of fault self-clearing for the motors in the group.Type: ApplicationFiled: October 16, 2019Publication date: April 22, 2021Applicant: Schneider Electric USA, Inc.Inventors: Kevin M.

Patent number: 10637383Abstract: A system and method is provided to monitor wear on a power factor correction capacitor in a motor system. The system and method obtains a baseline inductance angle, reactive power or power factor corresponding to a baseline power factor correction by the capacitor in the circuit; monitors a current supplied to the motor at a location upstream of the capacitor; monitors a voltage supplied to the motor, and determines a present inductance angle, reactive power or power factor based on the monitored current and voltage. The present inductance angle, reactive power or power factor corresponds to a present power factor correction by the capacitor. The system and method can then determine when the power factor correction of the capacitor has degraded to an unsatisfactory level based on a change in the inductance angle, reactive power or power factor from the baseline values, and take appropriate action.Type: GrantFiled: December 20, 2017Date of Patent: April 28, 2020Assignee: SCHNEIDER ELECTRIC USA, INC.Inventors: Richard K.

Patent number: 10424913Abstract: In accordance with an example embodiment of the invention, in an overload relay for a three-phase motor, an adjusted threshold for detected current phase unbalance is dynamically determined at which the relay will be tripped. The adjusted threshold is a function of a ratio of an average of currents in the three-phases to the rated full load current of the motor, i.e., motor load. As the motor load decreases, the adjusted current phase unbalance threshold is increased, causing the resulting trip time to increase, thereby increasing motor run time and reducing downtime.Type: GrantFiled: December 20, 2017Date of Patent: September 24, 2019Assignee: SCHNEIDER ELECTRIC USA, INC.Inventors: Kevin M.
