%0 Journal Article %T A BRIEF OVERVIEW OF STOCHASTIC INSTRUMENTS FOR MEASURING FLOWS OF ELECTRICAL POWER AND ENERGY %A Aleksandar Radonjic %A Dragan Pejic %A Vladimir Vujicic %J - %D 2019 %X This paper gives a brief overview of three instruments suitable for measuring the flow of electrical power and energy. The first instrument is a single-phase power analyzer, while the other two instruments are double and quadruple three-phase power analyzers. In addition to overviewing these instruments, the paper presents a possible improvement of a quadruple three-phase power analyzer. The implementation of this improvement would make it possible to use a quadruple three-phase power analyzer as support for the phasor measurement unit %K electrical power %K electrical energy %K power grid network %K stochastic instruments %K measurement accuracy %K phasor measurement unit %U http://casopisi.junis.ni.ac.rs/index.php/FUElectEnerg/article/view/4566
