A battery disconnect includes a housing, battery and load terminals, separable contacts electrically connected between the battery and load terminals, an operating mechanism structured to open and close the contacts, and a manual operator cooperating with the operating mechanism to open and close the contacts. A current sensor is structured to sense current flowing between the battery and load terminals. A circuit cooperates with the current sensor and the operating mechanism to trip open the contacts responsive to arc fault, overload and short circuit conditions associated with the sensed current. The circuit includes a first input structured to receive a remote on/off signal and a second input structured to receive an inhibit signal. The circuit cooperates with the operating mechanism to open and close the contacts responsive to the on/off signal, and to inhibit detection of the arc fault, overload and short circuit conditions responsive to the inhibit signal.

Direct current and battery disconnect apparatus

A system displays information from and controls electrical switching apparatus, such as circuit breakers. The system includes a plurality of circuit breakers having separable contacts and a plurality of conditions, such as bus temperature and contact wear. A plurality of sensors are structured to sense the conditions of the circuit breakers and to communicate the sensed conditions over corresponding wireless signals. A display and control unit is operatively associated with the circuit breakers and is structured to receive the corresponding wireless signals and display information corresponding to the sensed conditions or to control the circuit breakers based upon one or more of the sensed conditions.

Wireless system for one or more electrical switching apparatus

A system and method for current sensing includes a conductor configured to receive current flow therethrough and generate magnetic flux thereabout. The current sensor system also includes an anti-differential current sensor configured to monitor magnetic flux about the conductor. The anti-differential current sensor includes a pair of current sensors in opposing positions and disposed in the flux concentrating recesses of the conductor, and a processing component configured to receive feedback from each of the current sensors. The processing component is further configured to output a value indicative of the amount of current flow in the conductor.

A sensor apparatus is for a power bus including a plurality of characteristics. The sensor apparatus includes a housing; one or more sensors each adapted to sense a characteristic of the power bus; and a circuit adapted to transmit or receive a wireless signal. A processor includes a low-power mode and a routine adapted to wake up from the low-power mode, to input the sensed characteristic from the one or more sensors, to output a corresponding signal to the circuit to transmit as the wireless signal, and to sleep in the low-power mode. A power supply is adapted to power the sensors, the circuit and the processor from flux arising from current flowing in the power bus. The power supply includes one or more voltages.

Self-powered power bus sensor employing wireless communication

A switchgear apparatus includes a switchgear device, such as a circuit breaker, having a power bus, and an antenna element including an antenna member and one or more antenna leads. A material encapsulates the antenna member and is adapted to suppress dielectric breakdown through the material to the encapsulated antenna member from the power bus. The circuit breaker also includes a conductive housing having an opening receiving the antenna leads. The conductive housing is mounted on or proximate to the power bus. A sensor circuit is disposed in the conductive housing and is adapted to output a radio frequency signal to the antenna leads or to input a radio frequency signal from the antenna leads.

A sensor apparatus for a power bus including a current and a temperature includes a housing and one or more sensors. Each of the sensors is adapted to sense one of the current or the temperature of the power bus. A radio transceiver circuit is adapted to transmit a first wireless signal and to receive a second wireless signal. A processor is adapted to input the sensed current and the sensed temperature from the sensors and to output corresponding signals to the radio transceiver circuit in order to transmit the first wireless signal. A power supply is adapted to employ voltage produced by magnetically coupling the power bus to one or more coils, in order to power the sensors, the radio transceiver circuit and the processor from flux arising from current flowing in the power bus.

An apparatus for use in sensing electrical current in a conductor includes a flux concentrator and one or more magnetic flux sensors. The flux concentrator includes main sections which are formed of a magnetic material. One or more intermediate sections, formed of a nonmagnetic material, extend between the main sections of the magnetic flux concentrator. The main sections and intermediate section of the magnetic flux concentrator cooperate to at least define an opening through which a portion of the conductor extends.

Electrical current sensing apparatus

An electrical sensing apparatus includes a conductor having longitudinally extending sections with parallel central axes and a connector section which extends between the longitudinally extending sections. The connector section has a central axis which extends parallel to the central axes of the longitudinally extending sections. A magnetic flux sensor is disposed adjacent to the connector section to detect variations in current conducted through the conductor. The magnetic flux sensor may be at least partially disposed in a slot in the connector section and have a flux sensitive side surface which extends perpendicular to a central axis of the connector section. The magnetic flux sensor may include an electrically insulating material which is at least partially enclosed by the connector section and a Hall effect device which is supported by the electrically insulating material. The electrically insulating material may be disposed in engagement with the connector section.

An electronic throttle assembly uses a torque motor and mechanical system to position the throttle. The assembly is configured to keep the throttle slightly open during times of electrical power failure to the torque motor. Inherent electromagnetic qualities of the torque motor provide a reluctance torque that varies depending on internal stator/rotor geometry and is present in the absence of electrical power to the motor. A mechanical system provides a counter torque. Aligning the throttle to the desired slightly open position at a point where the reluctance torque is countered by the mechanical torque, allows an engine controlled by the throttle to continue to operate even if electrical power to the torque motor is lost.

Degraded electronic throttle operation method and system

An improved circuit interrupter having a solenoid in series with the line and load terminals with an armature operable to activate a trip mechanism within the circuit breaker upon experiencing current levels indicative of short circuit conditions. The traditional solenoid coil is replaced with a free form conductor stamped in a serpentine pattern with adjacent legs deformed slightly in opposite directions to permit an electromagnetic material to be disposed therebetween. Current is directed through the conductor progressively back and forth through the serpentine pattern and creates a magnetic field in the electromagnetic material which is sufficient to activate an armature when current levels approximate short circuit conditions.
