METHOD FOR MEASUREMENT OF ROOT-MEAN-SQUARE VALUE OF ALTERNATING CURRENT VOLTAGE

摘要

Method for measurement of root-mean-square value (RMSV) of voltage of alternating current relates to the area of electrical measuring engineering and can be used at development of accurate and broadband devices for measurement of alternating current. Main point of the invention is in previous determination of the model of real characteristic of transformer. The method is proposed as an alternative one by the method of zero comparison for determination of the RMSV of voltage of alternating current. The solution proposed makes it possible to increase accuracy of measurement of RMSV of voltage of alternating current and speed of measurement.
