An on-deck system 300 for non-destructively validating a machine part is provided. The machine part 30 is configured for use with a dynamoelectric machine or a turbomachine. The system includes a portable and hand-held infrared transceiver 310 configured to emit and receive infrared light, and a bandpass filter 320 configured to filter the infrared light. A crystal probe 340 is configured to contact the machine part, and one or more mirrors 330 are configured to direct the infrared light onto the crystal probe and subsequently back to the infrared transceiver/detector. The infrared transceiver is adapted to communicate with a notification device configured to output a notification of a test result.

A charging system for charging an electric vehicle includes a charging station and a charging network server, with the charging network server in network communication with the charging station and a mobile device application. The charging station and the charging network server include computing devices programmed to: store an authorization code at each of the network server and the charging station for authorizing charging of the electric vehicle when the charging station is off-line from the charging network server, process a charging authorization request at the charging network server sent from the mobile device application, transmit the authorization code from the network server to the mobile device application responsive to the charging authorization request and when the charging station is off-line, and authorize or deny charging of the electric vehicle based on whether an authorization code input to the charging station matches the authorization code stored on the charging station.

A housing (101,201,301,401) design and method of providing electromagnetic compatibility (EMC) by mitigating a slot (314,316) antenna in a corner region of a housing (101,201,301,401), the corner profile (220,320,420,520) including an electrically conductive insert (324,424, 424a,424b, 624,624a,824) that has a spring bias, such as a spring or coated plastic member, in a corner of the housing (101,201,301,401).
摘要:
A circuit breaker, comprising an enclosure comprising: - at least two arcing contacts that are movable axially relative to each other, between an open position of the circuit breaker in which the arcing contacts are separated from each other and a closed position of the circuit breaker in which the arcing contacts are in contact with each other; and - a gas inlet configured to blow an arc-control gas in order to interrupt an electric arc that is likely to form during movement of the arcing contacts from the closed position to the open position of the circuit breaker, wherein the arc-control gas comprises at least 80% of carbon dioxide; wherein the enclosure further comprises an adsorbing material, which adsorbs carbon monoxide that forms after ionization of the carbon dioxide during arcing, said adsorber being a metal-organic framework comprising nickel and/or iron.

An electric power system (500) includes an on-load tap changing (OLTC) transformer (550). The transformer includes a plurality of primary windings (554) and a plurality of secondary windings (556). At least a portion of one of the primary windings and the secondary windings are inductively coupled to each other. The system also includes at least one on-load tap changer (600) coupled to at least one of the primary windings and the secondary windings. The on-load tap changer is selectively configurable to regulate the portion of at least one of the primary windings and the secondary windings inductively coupled to each other. The system further includes at least one processor (115) coupled to the on-load tap changer. The processor is configured to adaptively regulate a voltage set-point of the on-load tap changer as a function of an adaptive OLTC transformer power flow dependent voltage set-point characteristic.

The present disclosure is directed to a coupling assembly (100) for a turbomachine (10). The coupling assembly (100) includes a liner (38) and a sleeve (52) at least partially positioned circumferentially around the liner (38). A frame (104) is positioned between the liner (38) and the sleeve (52). The frame (104) includes a first side wall (110), a second side wall (112), and a base wall (114) extending from the first side wall (110) to the second side wall (112). A block (106) is positioned between the liner (38) and the sleeve (52) and is movable relative to the frame (104) to permit the block (106) to move toward and away from the base wall (114). Moving the block (106) away from the base wall (114) causes the block (106) to exert an inward force on the liner (38) and the base wall (114) to exert an outward force on the sleeve (52).
摘要:
A system for optimal planning of electric power demand is presented. The system includes a node comprising one or more smart charging plug-in electric vehicles (SCPEVs), a processing subsystem, wherein the processing subsystem receives relevant data from one or more sources; and determines an optimized SCPEV load and optimal charging schedule for the node by applying an operations research technique on the relevant data.
摘要:
A method for data compression includes reading first data representing sensor data capture, compressing the data with a lossless algorithm, transmitting the compressed data as a reference frame, reading subsequent data, calculating a delta between the first data and the subsequent data, compressing the data delta, and determining if the compression ratio of the compressed data delta is within a predetermined tolerance threshold. If the compression ratio is within the threshold, transmitting the compressed data delta frame, and repeating the calculating, compressing, and determining steps for subsequent data; Else if the compression ratio is not within the threshold, compressing the current subsequent data and transmitting the result as an updated reference frame. Then repeating the calculating, compressing, and determining steps for subsequent data. A system and a non-transitory computer-readable medium for implementing the method are also disclosed.
