The influence of modern TV sets and monitors on the parameters defining the quality of electricity and the operation and safety of power grids

Abstract

This paper overviews European Commission regulations, directives of the European Parliament and the European Council, Polish laws and regulations as well as standards applicable to power quality, in particular the power factor and the higher harmonic content of currents and voltages in power grids. Power quality parameters for loads such as TV sets and monitors were measured and analyzed. The time waveforms of currents for these loads during standard operation and in stand-by mode were presented. The influence of the evaluated devices on the design and operation of modern power grids was analyzed with special emphasis on electrical safety.
