    摘要： 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.

    摘要： Partial discharge detection techniques are provided. In one aspect, a method (700, 800) of detecting partial discharge in an electrical power system (100) having a power electronics converter (120) is provided. A first current signal (I1) is captured in response to a first applied voltage (V1). A second current signal (12) is captured in response to a second applied voltage (V2), the second applied voltage (V2) being different than the first applied voltage (V1). The first current signal (I1) is set as a reference signal (I REF ). A difference signal (Δ N ) is determined based on the second current signal (12) and the reference signal (I REF ). A determination is made as to whether partial discharge is present based on the difference signal (Δ N ). The method (700, 800) may iterate, and for each iteration, the reference signal (I REF ) is refreshed on a rolling basis as a previously captured current signal ( I N -1 ) measured in response to a previously applied voltage ( V N -1 ). The applied voltage is also stepped up or down for each iteration.
