Harmonic Filter By Sree Nandhee's Technologies Pvt. Ltd.

We are praised for Making and Supplying of Harmonic Filters in Chennai, Tamil Nadu, India. Liebert AF3 latest technology to eliminate harmonic injected into the mains supply by non linear loads, as well supplies inductive power demanded by the load, so as to correct input power factor to near unity.

Current harmonic elimination is achieved by sensing load current and extracting harmonic current signal. This and the reactive current signal, together are used to generate a reference for the controlled current source connected at the PCC (point of common connection) of source and load.This results in mains supplying only real power for the load and reactive and harmonics being sourced from the AF3.This is carried out dynamically, so that any change in the load pattern or its nature is immediately responded without any manual intervention.
