    Abstract: This present disclosure generally relates to systems and methods of electrophoretic deposition (EPD) techniques for use in insulation systems at least partially encapsulating a semiconductor device, a conductive component and a substrate, such as insulation systems of semiconductor devices, busbars, or the like. Insulation systems formed using EPD processes may be designed to have a dielectric constant that decreases in a direction away from a substrate of the insulation system. This may improve insulation technologies since depositing coatings with sequentially arranged dielectric constants may improve resistance of the insulation system to high temperature, high electric fields, or the like.

    Abstract: An on-deck system for non-destructively validating a machine part is provided. The machine part is configured for use with a dynamoelectric machine or a turbomachine. The system includes a portable and hand-held infrared transceiver configured to emit and receive infrared light, and a bandpass filter configured to filter the infrared light. A crystal probe is configured to contact the machine part, and one or more mirrors 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.

    Abstract: A system and a method are presented. The system includes an electrically conducting material and an electrical insulation system. The electrical insulation system includes a layered insulation tape that has a first layer and a second layer. The first layer includes a mica paper and a binder resin in a range from about 5 wt % to about 12 wt % of the insulation tape. The second layer includes a composite of layered nanoparticles dispersed in a polyetheretherketone (PEEK) matrix. The second layer laminates the first layer. The method includes attaching the first layer and the second layer with or without the addition of further resin; using the layered insulation tape as a turn insulation and ground wall insulation for an electrically conducting material; and impregnating the system with a nanofiller-incorporated resin by a vacuum pressure impregnation method, to form an insulation system within the system.

    Abstract: Partial discharge detection techniques are provided. In one aspect, a method of detecting partial discharge in an electrical power system having a power electronics converter is provided. A first current signal is captured in response to a first applied voltage. A second current signal is captured in response to a second applied voltage, the second applied voltage being different than the first applied voltage. The first current signal is set as a reference signal. A difference signal is determined based on the second current signal and the reference signal. A determination is made as to whether partial discharge is present based on the difference signal. The method may iterate, and for each iteration, the reference signal is refreshed on a rolling basis as a previously captured current signal measured in response to a previously applied voltage. The applied voltage is also stepped up or down for each iteration.
