Abstract

Stochastic digital measurement method (SDMM) is a method that uses low resolution flash A/D converters, the most common one uses only 2 bit converters. Hence, the instruments that use SDMM are characterized by a very simple hardware, small number of systematic error sources, wide bandwidth, high reliability and robustness. The paper presents the latest results of its application in the power grid measurements. Simple hardware allows easy implementation of parallel measurements and high level of integration of functions of instruments that simultaneously measure multiple quantities – currents and voltages on the multiple channels, as well as derived quantities – power and energy.
