Szukana fraza: [Abstrakt = "This paper includes overview of present European Commission's regulations, European Parliament and European Council’s directives, Polish laws and regulations as well as standards in the field of power quality with particular reference to power factor PF and higher harmonic content in power network currents and voltages. The results of measurements of power quality parameters for loads such as TV sets and monitors have been presented. Time waveforms of currents for these loads during standard operation and in stand\-by mode have been shown. The influence of such devices on design and exploitation of modern power networks, especially taking into account electrical safety, has been analyzed."]
