W pracy przedstawiono wyniki pomiarów ilustrujących właściwości wybranych lamp z punktu widzenia sieci elektroenergetycznej. Do badań wybrano lampę halogenową, świetlówkę kompaktową oraz 3 różne lampy LED. Przedstawiono zastosowany układ pomiarowy oraz zmierzone przebiegi czasowe oraz widma częstotliwościowe prądu zasilającego badane lampy. Wyznaczono i przedyskutowano wartości wybranych parametrów...
This paper presents methodology of measuring the quality of electrical energy and monitoring the selected parameters of voltage and current waveforms in the photovoltaic systems. The presented methodology was based on the example of measurements carried out in the low power off-grid PV system.
This paper presents possible use of floating-point signal processor for the purpose of measuring harmonics and interharmonics and for detection of transient events in real-time. WPT and its characteristics to decompose signal into components were applied as calculation method. Also various wavelet-based and IIR filters were analysed. The main reason for that was to check the time used for the decomposition...
This paper presents methodology of defining the sources of interferences on the basis of measuring the quality of electrical energy and monitoring the selected parameters of voltage and current waveforms. The presented methodology was based on the example of industrial power network that supplied the new electroprecipitator cooperating with sulphuric acid recovery installation. After a few weeks of...
