    Author : Giovanni Zanuso; Viktória Fodor; Luca Peretti; Antonio Griffo; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industry 4.0; condition monitoring; multi-drive systems; EtherCAT; CAN; stator interturn faults; stator insulation; accelerated aging.; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Electric drives are widely used in industry, where they are also part of the plant communication architecture. This architecture is challenged by the Industry 4.0 initiative that aims to make the devices in industrial plants more interconnected and with additional functionalities. READ MORE

  4. 2. Charge transport in polymer-based insulating materials for high voltage applications: effect of single- and multi-layered structures

    Abstract : Polymer composites have been widely employed as electrical insulating materials for high voltage components and devices such as power cables, gas-insulated systems, rotating machines, line and post insulators, etc. Such materials are usually made by introducing inorganic oxides (SiO2, TiO2, Al2O3, MgO) into polymeric matrices e.g. READ MORE

  5. 3. Dielectric response and partial discharge measurements on stator insulation at varied low frequency

    Author : Nathaniel Taylor; Hans Edin; Shesha Jayaram; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electric power engineering; Elkraftteknik;

    Abstract : This is a study of potential improvements of diagnostic methods used on high-voltage generators and motors.  It considers offline electrical measurements on the main insulation of stator windings, where a sinusoidal voltage is applied between the winding and the stator-core, and the total current through the insulation (dielectric spectroscopy, DS) and the rapid current-pulses arising from discharges (partial discharge, PD) are measured.
