Optimal choice of the number of even harmonics demodulated from the excitation current of a sensor for precise dc voltage component detection in low voltage distributive grid as a strategy for suppression of the systematic error due to the grid voltage fluctuation
This paper addresses the problem of suppression of a systematic measurement error during the detection of a parasitic DC voltage component, superimposed to an AC voltage. As a sensor the toroidal transformer is employed. The origin of the error under scope is the fluctuation of ac voltage around its...
