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.

Increase Productivity through Harmonic Solution

Increase Productivity

Abstract- Harmonic solution is an engineer's approach to total productive maintenance (TPM) to Increase Productivity. No stoppage. No breakdown. No quality rejection. A 3500 TCD sugar milling unit was operating at 3000 TCD due to frequent drive stalling problem with dc mill motor. To increase productivity and sugar recovery, it installed a 2000A passive tuned harmonic filter in 2010, at a 3MW 415V Turbine Generator (TG).
