Active Harmonic Filter

The Active Harmonic Filters supplied by Saumita Controls is manufactured by MERUS, Finland. Merus A2-series active filters ensure guaranteed compliance with the harmonic distortion’s limits specified in IEEE 519, G5/4, IEC 61000 and other power quality standards and regulations followed by the Indian Utilities Merus A2-series Active Harmonic Filters are built on modern 3-level topology which brings several benefits compared to other active filters built on the conventional 2-level topology. In 3-level topology, the switching frequency and voltage stress are distributed among the two IGBTs. Reduced stress extends the lifetime of the power electronics. The efficiency and lower losses achieved with 3-level topology are excellent. These make the overall cost of ownership much lower compared to conventional solution Merus A2-series Active Harmonic Filters are equipped with sophisticated 7” Human Machine Interface (HMI). Commissioning of the device is simplified and Hassle free with the help of the built-in Commissioning Wizard. KEY FUNCTIONS:- Active harmonic filtering. Power factor correction. Voltage variation control and flicker mitigation. Load balancing in three-phase systems. The Harmonic filters are customized for demanding Applications and are available from 480V up to 1000V.
