Voltage distortion of 6.6 kV distribution systems has been increasing recently especially in commercial areas. Harmonic currents of certain orders are amplified and voltage distortions are genarated by the resonance between system impedance and static capacitor under the leading power factor condition.
This paper describes the results of the test on suppression effects on model systems and an actual system. The effect of the use of an active power filter on the resonant harmonics of the system including capacitor was verified.
