Solving power system harmonic resonance, Improving power quality and Eliminating electrical failure

Abstract: An Electrical Arc Furnace near a hyperactive railway traction line was facing electrical failure from an unusual power quality harmonic distortion problem. The Gigantic 22kA copper bus bar used to overheat visibly red-hot, vibrate audibly loud loosening nuts and bolts and wear out affected plates. In-addition, it frequently encountered other harmonic problems like bulging and blasting of detuned capacitor, motor overheating and failures, HPMV lighting ballast failures, 33kv fuse blowing and overheating of the Electric Arc Furnace transformer.
