    Opis:
    The paper presents a set of equations enabling analysis of operation of three-phase three-winding transformers under asymmetric load. For a selected asymmetric state of such a transformer the computation leading to analysis of characteristic output parameters of the transformer is carried out with the help of the Mathcad software.

    Opis:
    In the paper a vibroacoustic method of diagnostics of the mechanical state of an active part of a transformer is presented. The analysis is performed on the signal of bank vibrations in a transient stage of work of an unloaded transformer - during the first few seconds after connecting to the power supply. The method is based on SSM algorithm (Spectral Subtraction Method) reducing the ‘disturbing’ impact of magnetostriction phenomenon on the measurement. It was concluded that using, in the process of diagnostics of an active part of a transformer unit, only the vibroacoustic method does not provide certain conclusions. Experimental research proved high usefulness of the presented V-SSM method (Vibroacoustic Spectral Subtraction Method) when accompanied by FRA method (Frequency Response Analysis) in winding defect diagnostics.

    Opis:
    The diagnostics of power transformers is very important in order to plan repairs and replacements of aged population of transformers operated in Poland and Europe. One of these methods is Frequency Response Analysis - FRA. It can detect any mechanical changes in active part of transformer, which may even lead to serious faults of units in service. As the method is based on comparison of measured curves, which are not always available from previous measurements the computer modeling was applied to create models of windings’ response. The paper presents examples of models created for simple windings and also for real transformer with some deformations of windings simulated.

    Opis:
    The paper deals with analyses of multiphase fractional slot permanent magnet synchronous machines with concentrated windings. The advantages of studied machines have been discussed. Studied in the paper multiphase machines contain the number of phases in multiple of 3, facilitating the application of commonly used 3–phase intelligent power modules to build the multiphase supply system. The coding convention, an algorithm and software for synthesis and analysis of multiphase fractional slot concentrated windings have been developed. To verify presented algorithm the field approach has been employed. The professional FEM package Maxwell has been used to determine functional parameters of the test machine with different types of windings. Selected results of simulations of studied multiphase machines with different phase number and winding layouts have been presented and analyzed.
