METHOD OF DETERMINING AMPLITUDE AND PHASE OF EQUIVALENT CURRENT SINUSOID IN CIRCUIT WITH FERROMAGNETIC CORE |
摘要 |
FIELD: electrical engineering. ^ SUBSTANCE: method comprises measuring instantaneous values of sinusoidal voltage and nonsinusoidal current in the circuit. The power averaged over the period and effective values of voltage and current can be judged from the digital readings of instantaneous values of sinusoidal voltage and nonsinusoidal current in the circuit. The phase of the equivalent sinusoid is determined from the ratio of the power to the product of their effective values. ^ EFFECT: enhanced accuracy of determining. ^ 3 dwg, 2 tbl |
