Abstract: 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.

Abstract: Techniques for automatically configuring a computing device in a computing environment are provided. One embodiment includes determining that the computing device has been added to a computing environment and that at least one feature of the computing device is unconfigured. Device name data specifying at least two potential device identifiers for the computing device is received from a plurality of endpoint devices communicatively coupled to the computing device. A first device identifier is selected from the at least two potential device identifiers and device configuration data associated with the first device identifier is requested from a device configuration server. The at least one feature of the computing device can then be configured using the device configuration data.

Abstract: A cable reel assembly in an electric vehicle supply equipment (EVSE) having a reel around which a cable is coiled. A shaft supporting the reel bears discs that rotate with the reel, and calipers coupled to the discs stop them and the reel from rotating. The power L1 and L2 conductors in the cable are electrically connected to the discs, and the calipers are electrically connected to the power source for the EVSE so that the calipers provide mechanical and electrical connection when actuated. Optionally, slip rings coupled to the shaft are connected to the control pilot and proximity signal conductors in the cable. Thus, during cable re traction, the control pilot and proximity signals are still provided to the EVSE, but the power conductors are decoupled from the power source. Only when the calipers are actuated to brake the discs is current flow permitted.

Abstract: In an electromagnetically controlled actuator of an electrical contactor, switching is done by the actuator with a set of fixed contacts and a set of movable contacts. The movable contacts are carried on a movable contact carrier. The movable contact carrier is coupled to and driven by an armature surrounded by a coil. The armature carries a coupling shaft, and the coupling shaft carries at least part of a bistable coupling mechanism which joins the armature to the movable contact carrier and allows the movable contact carrier and armature to keep the fixed and movable contacts separated when a short circuit current creates a contact welding situation.

Abstract: A load starting system in which an upstream controller determines the sequence and timing for starting a group of loads in the most efficient and timely manner. The sequence and timing is determined by one or more real-time operational characteristics, device rating characteristics, customer/user characteristics or learned/historic characteristics or by a combination of the one or more real-time, device rating, customer/user or learned/historic characteristic.

IPC: H02H7/08
Abstract: 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.

Abstract: An add-on adapter 110 enables a single charging port 102 of an electric vehicle charging station 100 to simultaneously charge two electric vehicles. An adapter controller 120 determines the available charging rate offered by the charging station. Electric vehicle charging handles 150A, 150B are determined to be connected to the electric vehicles. A charge sharing control circuit 300 in the adapter controller, determines modified available charging rates to be offered for simultaneously charging the electric vehicles. The modified available charging rates are based on the connection states of the electric vehicles and the available charging rate offered by the charging station. The adapter controller controls two contactors 130A, 130B to switchably connect a charging station power socket to the electric vehicle charging handles, to provide shared power at the determined modified available charging rate to the electric vehicles, for simultaneous charging.
