    摘要： A system for detecting partial discharge in electrical components may include a control system that may operate a drive in an industrial automation system. The industrial automation system may include the electrical components being analyzed for partial discharge. The system may also include one or more acoustic sensors that may detect one or more acoustic waveforms generated within at least one of the electrical components. The system may also include a monitoring system that may receive the acoustic waveforms from the acoustic sensors and determine whether the one electrical component is experiencing partial discharge based on the acoustic waveforms. The monitoring system may then send a notification to the control system when the one electrical component is determined to be experiencing partial discharge, such that the notification indicates that the one electrical component is experiencing partial discharge.

    摘要： The disclosed apparatus provides a simple and low cost solution of reducing voltage stress on AC motors and cables in VFD fed motor systems without connecting apparatus to live circuits. Disclosed examples include apparatus to couple a motor drive to a motor, including a cable with a first end coupled with an output of a motor drive, a second end coupled with a motor, a plurality of conductors to convey an output signal of the motor drive between the first and second ends to drive the motor, and a plurality of shields, with a conductive junction to couple tap points of at least two of the shields together. Resistors can be used to connect the tap points to the conductive junction to provide an impedance in series with the corresponding shield to reduce voltage stress to the motor or the cable. In certain examples, the shields include a semiconductor material to provide an impedance between the first end and the conductive junction to reduce voltage stress to the motor or the cable.
