ELECTRIC-QUANTITY MEASURING APPARATUS AND ELECTRIC-QUANTITY MEASURING METHOD

A frequency-coefficient calculating unit calculates, as a frequency coefficient (fc), a value ((v21+v23)/(2v22)) obtained by normalizing, with a differential voltage instantaneous value (v22) at intermediate time, an average ((v21+v23)/2) of a sum (v21+v23) of differential voltage instantaneous valu...
