    摘要： A system and method for detecting a rotor fault condition in an AC induction machine is disclosed. The system includes a processor programmed to receive voltage and current data from an AC induction machine, generate a current frequency spectrum from the current data, and identify rotor-fault related harmonics in the current frequency spectrum. The processor is also programmed to calculate a fault severity indicator using the voltage and current data, identified rotor-fault related harmonics, and motor specifications, analyze the fault severity indicator to determine a possibility of rotor fault. The processor generates an alert based on the possibility of rotor fault.

    摘要： A system and method for controlling an AC motor drive includes a control system programmed with an algorithm configured to optimize operation of the motor drive. Specifically, the control system is programmed to input an initial voltage-frequency command to the drive. The initial voltage-frequency command includes a voltage reference and a frequency reference corresponding to an operating point of an initial voltage/frequency (V/Hz) curve. The control system monitors a real-time output of the drive, modifies the voltage reference based on the real-time output of the drive, and transmits a modified voltage-frequency command to the drive. The modified voltage-frequency command corresponds to an operating point of a modified V/Hz curve defined by the modified voltage reference and the initial V/Hz curve.

    摘要： A re-enterable enclosure for a cable splice includes a first cover member and a second cover member configured for engagement with each other, and movable between an open position and a closed position. The first and second cover members form a cavity for enclosing the cable splice when the cover members are in the closed position. Internal walls in at least one of the first and second cover members are configured to define a sealant containment space that at least partially surrounds the cavity. At least one latch is configured to maintain the first and second cover members in the closed position, the at least one latch configured to exert a compression force along a line extending through the sealant containment space.
