Line Load Reactors Dealers

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)

APPLICATIONS : Power Factor Panels, Furnace Panels, UPS, Fluroscent Lamps Om make reactors are designed to meet specific design criteria such as Q factor, inductance tolerances etc. series line reactors shall be designed for harmonic filtering service and for slowing the rate of rapid current charges. The reactors shall be UL component - recognized and shall be built to comply to UL 508 construction shall be of copper wire - wound on magnetic steel cores. Series line reactors shall be sized appropriately for the total connected load. Design maximum temperature rise for reactors shall be 115°c on bobbin wound and 155°c on form wound devices at rated circuit. Non-linear equipment generate harmonic as multiples of a fundamental frequency such as AC/DC motor speed controllers, are furnaces compact fluorescent lamps, uninterruptible power sources. As a result of this fact besides the fundamental frequency, 3rd, 5th, 7th, 9th, 13th, harmonic are generated.
