The new line of StacoSine® Active Harmonic Filters from Staco Energy Products dynamically correct a wide spectrum of harmonic orders present in most water treatment plants (due to the presence of multiple motors and pumps). StacoSine uses power electronics to monitor a non-linear load and dynamically correct every harmonic order from the 2nd to the 31st. Through an injection and cancellation process, the sine wave is restored and distortion is reduced to less than five percent THD, meeting stringent IEEE 519 standards.
