Harmonic Filters Solutions


The growing use of modern electricity electronic apparatus (drives, uninterruptible power supplies, etc.) produces nonlinear modern and thus hundreds the community with harmonics. The capacitance of the power capacitor forms a resonant circuit at the side of the feeding transformer. Experience shows that the self-resonant frequency of this circuit is generally between 250 and 500 Hz, i.E. within the place of the 5th and seventh harmonics. Typical hundreds requiring harmonic filtering consist of 6 pulse drives (AC / DC), 3 section UPS, frequency converters
