METHOD MEASURING EFFECTIVE VALUE OF ALTERNATING VOLTAGE ( VARIANTS )

摘要

electric measurement technology. SUBSTANCE: invention is related to measurement of actual value of alternating voltage by evaluation results of samples of such voltage. In agreement with proposed method number of samples of instantaneous values of voltage is chosen equal to three with sinusoidal form of measured voltage and equal to ( 2N+1 ), where N is number of harmonics with non- sinusoidal form of voltage. EFFECT: increased measurement accuracy without substantial rise of number of samples. 2 cl, 3 dwg
