Passive Harmonic Filters

Description

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 500 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 99% efficiency and installed at the typical three phase voltage of 480 VAC (+/- 10%), at 60 Hz (+/- 1 Hz), these proven products reduce harmonics, to meet IEEE-519 (2014). Filters are available in two model types (FN3412) <5% THDi and (FN3418) 7-10% THDi.

Standard products are panel mounted (to 250 HP) and open type (to 500 HP), which are ideal for OEM and system integrators. Various NEMA rated enclosed filters are also available for facility installation. 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.
