MEASURING TECHNIQUE FOR ACTIVE AND REACTIVE CURRENT COMPONENTS OF BALANCED THREE-PHASE SUPPLY MAINS Russian patent published in 1997 - IPC

Abstract RU 2093840 C1

FIELD: electric measurement technology. SUBSTANCE: technique involves measurement of projections of two phase currents on line voltage of these phases and calculation of active and reactive components of current as difference of signals and their sum proportional to mean values of phase currents modulated by rectangular pulses shaped from line voltage by using these projections. EFFECT: improved measurement accuracy and facilitated procedure. 2 dwg
