APPARATUS FOR MEASURING DISTORTION POWER QUALITY INDEX AND METHOD OF OPERATING THE APPARATUS |
摘要 |
<p>A method of measuring a power quality index, including: measuring a total current waveform of an ingress from a customer, and a current waveform and a voltage waveform of each of at least one load installed at the customer; computing a load composition (LC) of the customer using the total current waveform of the ingress and the current waveform of each of the at least one load; computing a total harmonic distortion (THD) of each of the at least one load using the current waveform and the voltage waveform of each of the at least one load; and computing a distortion power quality index (DPQI) of each of the at least one load using the LC and the THD.</p> |
