    Estimation of the inductive current transformer derating for operation with distorted currents
    (2014) Kaczmarek, Michał
    The aim of the paper is to present a new method for estimation of the CT (Current Transformer) rated primary current and / or load of the secondary winding derating levels for transformation of distorted current in relation to the rated values fixed for transformation of sinusoidal current. This ensures the values of the CT composite errors/transformer correction factors as resulting from its IEC 60044-1/IEEE C57.13 accuracy class in condition of distorted currents transformation.

    Transfer of disturbances through the voltage transformers
    (Wydawnictwo Politechniki Łódzkiej, 2010) Kaczmarek, Michał
    This article was based on fragments of the authors` PhD dissertation and relates only to part of the considerations contained in it. The objects of the publication are metrological analysis of the voltage transformers operation during the transfer of distorted voltages. These considerations provide an introduction to establish the relationship between the metrological characteristics of voltage transformers of different constructions and their accuracy during evaluation of the voltage quality supplied to customers through the low and medium voltage power networks.
