Schaffner EMC introduces ECOsine® 60 Hz Passive Harmonic Filters which remove harmful harmonics of a pre-determined order, to increase the reliability of supplied power, and thus extend the service life of downstream components. With plug-and-play convenience and more compact dimensions than comparable products, they are easily installed and commissioned. Proven in industrial settings, Schaffner passive harmonic filters are ideal for use with non-linear loads such as motor drives (nominally 5 HP to 250 HP), equipment with front-end 6-pulse rectifiers, fans, pumps, HVAC equipment, DC fast chargers, and more.
Passive harmonic filters can improve the productivity by eliminating harmonic-related downtime in varied industrial applications such as manufacturing, water/wastewater treatment, factory automation, mission-critical processes, and more.
Designed to operate at 98% efficiency and installed at the typical three phase voltage of 480 VAC (+/- 10%), at 60 Hz (+/- 1 Hz), these proven products reduce harmonics to 7-10% THDi, and comply with IEEE-519, table 10-3. As not all applications require a THDi of <5%, the FN3418 filter design is a more economical approach for the mitigation of harmonics. Panel mounted design is easily installed. Lightweight and quiet operating, proven ECOsine® Passive Harmonic Filters are equally suited for new installations and retrofits.
Harmonics – A Silent But Deadly Problem
Harmonics are generated by nonlinear components in electrical systems, which distort the sine wave. Increasing usage of power electronics causes a corresponding increase in voltage distortion, or harmonics. Common electrical components like motors, pumps, fans, automation equipment, DC fast chargers, equipment with front-end six-pulse rectifiers, and more, all introduce harmonics into the electrical system. When harmonics are present they can manifest themselves with short-term and long-term consequences.
High harmonic distortion can cause failures or malfunctions of electrical devices. Harmonics also cause a temperature rise in the electrical network and in equipment, resulting in losses and shorter service life. Passive harmonic filter, like the ECOsine® Passive, when tuned to the offending harmonic order, corrects the sine wave, before the harmonics can cause any damage to the electrical system or equipment.
