Mahabalipuram, 2013 to 2017, Repeat jobs. Faced problem with UPS active harmonic filter.

PROJECT DETAILS
Was facing CNC, UPS & chiller vfd drives electronics card failures, lighting ballast, and motor burning issues and in addition voltage sag (fluctuation) tripping for CNC m/c. Local Utility company/ TNEB mandated limiting harmonics at it 11kv.
RESULTS ACHIEVED
Installed 831A main transformer and a 88A chiller end harmonic filters, mitigated harmonics within IEEE 519 norms, and eliminated all failures.

Solving power system harmonic resonance; improving power quality and eliminating electrical failures

Abstract: An Electrical Arc Furnace in the vicinity of a hyperactive railway traction line was facing an unusual power quality harmonic distortion problem. The Gigantic 22kA copper bus bar used to overheat visibly red-hot, vibrate audibly loud loosening its nuts and bolts and wear out the bus bar's affected plates.

Solving failures in VFD, DC drives and motors; Enhancing production by 25%, and Slashing energy bill by 9%

Abstract: In this case study, a world leader in non-ferrous metal industry engaged in the manufacturing ACSR conductors for HT and EHV electrical power transmissions and distributions, had been facing high incidence of operational problems across its plants A and B, due to bad Power Quality and high harmonic distortions with its electrical power systems. The problem arose because of two reasons. First, it was using over 60% Non-Linear-Loads in the forms of DC-drives in rolling mills, Variable-Frequency-Drives (VFD) in the conductor making process and PLC in control system.

Enhancing 3P, Power, Productivity, and Profitability; solving drive stalling and increasing sugar recovery

Abstract- A 3500TCD sugar factory installed across 3mw 415v TG four DC Mill drives each 450kw and highly fluctuating cane preparation section's slip ring induction motor loads namely 2nos 560kw Fiberizer, 225kw Leveler and 187kw Chopper. It wanted uninterrupted power export from its 6mw 11kv TG and connected across it stable linear loads of boiling and sugar houses through a set of 3.15mva and 1.5mva, 11kv/415v, Dyn11 transformers.

Problem of electrical blast from VFD harmonics; and a methodology for trouble shooting and increasing productivity

 Abstract - An IPP with a 25mw power plant and a 5000TCD sugar milling unit was facing a power quality harmonic distortion problem that starting with occasional tripping of its power plant eventually forced it to shut down its operation for several days. It had completed its first anniversary without any harmonic problem but during its 2nd years of operation it started off with a massive blast of a 6300A incomer ACB at the power plant's auxiliary PCC panel. Within a span of next 4-weeks it blasted off one by one several other switch gears, ACBs and MCCBs.
