Page 13: Introduction To The Low Harmonic Drive
VLT AQUA Low Harmonic Drive Instruction Manual 3 Introduction to the Low Harmonic Drive 3 Introduction to the Low Harmonic Drive 3.1.1 Working Principle The VLT Low Harmonic Drive is a VLT High Power adjustable frequency drive with an integrated active filter. An active filter is a device that actively monitors harmonic distortion levels and injects compensative harmonic current onto the line to cancel out the harmonics.
Page 14: Ieee519 Compliance
VLT AQUA Low Harmonic Drive Instruction 3 Introduction to the Low Harmonic Drive Manual 3.1.2 IEEE519 Compliance Low harmonic drives are designed to draw an ideal sinusoidal current waveform from the supply grid with a power factor of 1. Where traditional non- linear load draws pulse-shaped currents, the low harmonic drive compensates for this via the parallel filter path which lowers the stress on the supply grid.
