Appl. No.:

13/135282

Inventors:

Kevin Jefferies - Raleigh NC, US
Timothy B. Phillips - Raleigh NC, US
Benjamin W. Edwards - Knightdale NC, US

Assignee:

Schneider Electric USA, Inc. - Palatine IL

International Classification:

H02H 3/00

US Classification:

361 87

Abstract:

A method and apparatus for composing a desirable trip curve, such as an I*t trip curve, for an electrical protective device from at least one less desirable trip curve, such as an I*t trip curve. The method is accomplished by defining a selected parameter of the desirable overload trip curve and defining the selected parameter as a function of one or more monitored input values, such as current, trip class or phase unbalance, and modulating the selected defined parameter value between a maximum boundary trip curve and a minimum boundary trip curve. The modulated parameter is used to adjust the less desirable trip curve such that it has the characteristics of the desired trip curve. The method is implemented by one or more electrical circuits (filter circuits) representing the less desirable trip curve(s) and composing an output signal representing the desirable trip curve by modulating between the one or more electrical circuits.

US Classification:

324511

Abstract:

Systems, methods, apparatuses, and computer-readable media provide electric supply equipment configured to perform diagnostics. The electric supply equipment may include a receptacle for forming a closed circuit loop. The electric supply equipment includes a connector for charging devices, such as electric vehicles . The connector may include one or more conductors, some of which may be wrapped with insulation. When the connector is not used for charging, the connector may be connected to a receptacle of the electric supply equipment . Thus, the electric supply equipment , via the receptacle , may form a closed loop circuit with the conductors. Further, the electric supply equipment may include a diagnostic unit for performing diagnostic tests on the conductors. In particular, the diagnostic unit may access ends of the conductors via the receptacle

International Classification:

H04L 12/24
H04L 12/42

Abstract:

A method and system are provided to facilitate the commissioning of a distributed system. The method and system obtains a base configuration which defines an expected virtual topology for a distributed system, and identifies via a control device a physical network topology of the distributed system to commission the distributed system. The control device performs network discovery to identify a plurality of connected devices that are communicatively coupled thereto, and to collect device information for each connected device relating to its identity and relative position in the distributed system which has connected devices or associated subnetworks connected in a ring network topology. The collected device information for the plurality of connected devices is compared to the expected virtual topology from the base configuration to determine an identity and physical location of the plurality of connected devices and associated subnetworks in the physical network topology of the distributed system.

International Classification:

G01R 27/18
G01R 31/00

Abstract:

A measurement module receives a defined system topology and system component characteristics information for a system. The measurement module calculates an expected system impedance for the defined system topology. The measurement module collects one or more impedance measurements using a high frequency voltage stimulus. Finally, the measurement module compares the one or more impedance measurements with the expected system impedance to determine adequacy of protective grounding of the system.

International Classification:

G01R 19/25

Abstract:

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.

International Classification:

H02H 7/08
H02H 7/085

Abstract:

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.
