  • Novel Nonlinear High Order Technologies for Damage Diagnosis of Complex Assets
    Publication

    - Electronics - Year 2022

    For the first time worldwide, innovative techniques, generic non-linear higher-order unnormalized cross-correlations of spectral moduli, for the diagnosis of complex assets, are proposed. The normalization of the proposed techniques is based on the absolute central moments, that have been proposed and widely investigated in mathematical works. The existing higher-order, crosscovariances of complex spectral components are not sufficiently...

  • Diagnostyka łożysk silnika indukcyjnego z wykorzystaniem analizy prądu silnika metodą potrójnej kowariancji.
    Publication

    - Year 2017

    Przedmiotem niniejszej rozprawy doktorskiej jest opracowanie nowej metody diagnostyki łożysk w silniku indukcyjnym opartej na pomiarach i analizie prądu zasilającego silnik. Ze względu na ciągłe doskonalenie i rozwój badao w kierunku metod prądowych, za pomocą których możliwa byłaby diagnostyka całego silnika, temat ten jest cały czas otwarty i jak najbardziej aktualny. Rozdział pierwszy zawiera wprowadzenie w zagadnienia będące...

  • Induction motor bearings diagnostic indicators based on MCSA and normalized triple covariance
    Publication

    - Year 2017

    Induction motors are one of the most widely used electrical machines. Statistics of bearing failures of induction motors indicate, that they constitute more than 40% of induction motor damage. Therefore, bearing diagnosis is so important for trouble-free work of induction motors. The most common methods of bearing diagnosis are based on vibration signal analysis. The main disadvantage of those methods is the need for physical access...

  • Novel condition monitoring of induction motor bearings via motor current signature analysis
    Publication

    The paper authors are researching the assessment of bearing conditions in induction motors. The methods developed by the authors are based on measurements and analysis of the motor supply current, which is particularly attractive in the absence of access to the engine. The article provides an overview of selected methods of induction motor bearings diagnostic based on Motor Current Signature Analysis (MCSA). However, there is no...

  • Induction Motor Bearings Diagnostic Using MCSA and Normalized Tripple Covariance
    Publication

    - Year 2015

    Diagnosis of induction motors, conducted remotely by measuring and analyzing the supply current is attractive with the lack of access to the engine. So far there is no solution, based on analysis of current, the credibility of which allow use in industry. Statistics of IM bearing failures of induction motors indicate, that they constitute more than 40% of IM damage, therefore bearing diagnosis is so important. The article provides...
