PROJECT DETAILS
Submerged electric arc furnace 6mva, 33/0.150kv for Pig Iron manufacturing. Installed 33kv, 3.8mvar tuned harmonic filter and solved 24kA bus bar failures- heating/noise/vibrations/ worn-out due to power system harmonic resonance.
RESULTS ACHIEVED
Troubleshooting electrical harmonics and resonance failures by installing 33kv passive harmonic filter

Eliminate Electrical Failure

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.
