PROJECT DETAILS
Head Office of Murugappa conglomerate that accommodates 1300 employees. Local Utility mandated harmonic limits. In-addition was facing failures with air conditioning compressor motors, transformer, Lighting ballast failure, computer cards and SMPS.
RESULTS ACHIEVED
Installed 750A and 646A tuned harmonic filters and that resolved all harmonic failures and limited harmonic distortions within CEA 2007 and IEEE 519 norms of local the utility.

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.
