MULTIELEMENT ARITHMETIC MEASURING METHOD OF ALTERNATING CURRENT SIGNAL

摘要

PURPOSE:To allow even a general operational element to perform sufficiently processing by dividing the time of an optional period and reading time-division data continuously, then calculating respective sampling data at a time to considerably prolong a data processing time. CONSTITUTION:Respective inputs in an optional period of an AC voltage and current signal input waveform are time-divided into numers of sampling sections with the same time limit and respective time-division sampling data are read by sample holding circuits 14 and 15 successively. Read results are stored in a memory part 19 at every time, time-division identical-time-limit sampling data on the voltages and currents of active power and apparent power are processed mutually by an arithmetic processor 18, and arithmetic results are totalized and outputted as arithmetic measurement data.
