Method for measuring alternating current (AC), involves intending correction value from totality of measured instantaneous values of AC fluent for correcting instantaneous values of individual AC and to determine corrected values of AC

摘要

The method involves measuring the sequentially instantaneous values of individual AC, which are fed over three directors/guards (5-7) of the three-wire system (1) into AC mains (3). The correction value from the totality of measured instantaneous values of same time AC fluent is intended and is used for correcting the measured instantaneous values of individual AC, in order to determine corrected values of individual AC. The instantaneous values at the same time of AC flowing is determined to be measured at common measuring time dot or in a common measuring time space.
