  • Page 49: Filter Application

    Schaffner Group User and Installation Manual Ecosine max 7 Filter application Ecosine max passive harmonic filters are designed to mitigate harmonic current of non-linear loads, particularly of three-phase diode-type rectifiers. Contrary to “bus-applied or PCC (Point of Common Coupling)” filters, which are being installed e.g. at the main feeder, ecosine passive harmonic filters are specifically designed to be used with either an individual non-linear load, or with a group of non- linear loads.
