| Research Abstract |
From point of energy saving and greening, the real-time observation of the power status and the identification of harmonic resources from power conditioning apparatuses becomes an important engineering issue. In this study, first, the author has proved the validity of the capacitor voltage divider measurement method using his devised voltage-current sensor of resin molded type through the electric filed analysis based on finite element method. And he has tried to develop the measurement system, where the high accuracy power factor estimation and the identification of harmonic resources are feasible.
