Abstract
As the increasing of non-linear load, we have a growing interest in power quality. Power quality has come to the voltage quality. Voltage harmonics consist in at the PCC by the non-linear load. Capacitor is generally used for the power compensation and as the passive filter by the serial connection with reactor. Capacitor has low impedance as the frequency increases, so easily fall down by the harmonic component of non-linear load. Small voltage of low-order acts on quite a few at the capacitor by the current increase. In this paper, we measured the magnitude and angle of voltage at the PCC and calculated under the same condition. we checked out that lower voltage of higher order produces current magnification.
