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.

Solve VFD Drive Failure

VFD Drive Failure

Abstract:- An ACSR conductor manufacturing plant was facing high incidence of DC motor and AC VFD Drive Failure due to bad power quality and high harmonic distortion. The company is a world leader in non-ferrous metal industry. It manufactures ACSR conductors for HV and EHV power transmission and distribution lines. It had been facing a high incidence of operational problem across its plants A and B. It affected all electrical and electronic equipment with its conductor making process.

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).

Mitigate VFD Harmonic

VFD Harmonic

Abstract - VFD Harmonic forced a power plant to shutdown due to power quality failure. Starting with drive tripping it blasted switch gear, bus bar & electrical panel. This IPP with a 25mw, 11kV, 50Hz power plant and 5000TCD sugar milling unit had completed its first anniversary without harmonic problem. But during 2nd year's operation, it started-off with a massive blast of a 6300A Air Circuit Breaker (ACB). It was at the incomer of an electrical panel. The 415V PCC panel was supplying to sugar plant's process load.
