The paper describes a field of filters for high-speed analog signal processing, whose transfer function is affected by the existence of real input impedances of current active elements. The influence of this input impedance is analyzed in detail. This is indicated by both the additive error and the multiplicative error. Novel filter circuits, which partially eliminate the influence of this input impedance,...
In this paper a new fault classification method, based on environmental electromagnetic field measurement, is presented. The fault type is recognized by analyzing two dimensional electromagnetic field, measured in prescribed point on the pole of distribution line, transformed into frequency domain. The validity of method is evaluated by means of classifying the fault type via electromagnetic field...
Due to its simple structure and lower price, the resistive type superconducting fault current limiter (RSFCL) is being used widely in practical experiences. Since these equipments are installed to provide high levels of power quality for sensitive consumers, it is necessary to investigate their harmonics generation. In this paper harmonics generation of a RSFCL is considered and a method is presented...
