Information × Registration Number 0211U002451, 0109U000520 , R & D reports Title Automatization system of precision voltage measurement of alternations current in wide frequency range popup.stage_title Head Tuz Yulian Mikhailovich, Registration Date 09-02-2011 Organization Research Institute of Experimental Research Automation of National Technical University of Ukraine "Kiev Polytechnical Institute" popup.description2 The iterative algorithm for an AC voltage measurement based on a thermal electric comparison was proposed, the models of apparatus for precision AC voltage measurement were created. Methods for AC voltage measurement in a wide range of frequencies based on the interpolation algorithm were proposed and the system was created. The dependency of approximation errors on a node points placing was obtained, dependency of model coefficients errors on errors of a node points coordinates measurement and dependency of equation root determination errors on model coefficients errors were obtain as well. The influence of systematic and random errors was considered. The models of precision AC voltage measurement apparatus of the foreign production as well as the domestic production were created.
