METHOD FOR DETERMINING ACTIVE POWER OF SINE-WAVE CURRENT IN COMPLEX-IMPEDANCE CIRCUIT

摘要

FIELD: electric and radio measurement technology. SUBSTANCE: method involves measurement of current and voltage across analyzed equipment and across transformer secondary winding, as well as total voltage, approximation of two lowest values of measured voltage, and calculation of power factor using data obtained; then voltage across windings is rectified and DC voltages are compared by using compensation method. EFFECT: improved measurement accuracy and facilitated calculation procedure. 4 dwgp
