PLL AND NUMBER OF SAMPLE SYNCHRONISATION TECHNIQUES FOR ELECTRICAL POWER QUALITY MEASURMENTS

Richárd Bátorfi

Abstract

Today and in the future the measuring and analysing of electrical energy is a significant topic because its quality and consumption has more and more importance in scientific means and also practical. Since power frequency is fluctuating measurements must be synchronised to the network frequency to avoid spectral leakage error. In this paper two synchronisation methods are shown and compared.
