The need for large shunt reactors appeared when long power transmission lines for system voltage 220 kV & higher were built. The characteristic parameters of a line are the series inductance (due to the magnetic field around the conductors) & the shunt capacitance (due to the electrostatic field to earth). An equivalent diagram for a line is show in the figure below, Both the inductance & the capacitance are distributed along the length of the line. So are the series resistance and the admittance to earth. When the line is loaded, there is a voltage drop along the line due to the series inductance and the series resistance. When the line is energized but not loaded or only loaded with a small current, there is a voltage rise along the line (the Ferranti-effect)

Filter reactors are our core competency at Quality Power. We have supplied hundreds of reactor upto 145kV system voltage and covering the entire frequency spectrum. Recently we have supplied 2nd Harmonic and 3rd Harmonic filters for Ms Gunung Garuda Steels Ltd, Indonesia.Also we posses a Majority share in the Filter Reactors in South Asian Region and is a well established brand in this part of the world. Alternatively we have exported filers to around 11 countries across the world. We also have executed Harmonic study, Analysis and Execution of the whole Filter bank at Ms Bhushan Steel & Power Ltd at Jharsiguda, Orissa.
