Turbo energy Ltd, Paiyanoor

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.

Turbo energy Ltd, Pulivalam

Ranipet, 2013 to 2016, Repeat jobs.

PROJECT DETAILS
Was facing CNC and UPS 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 incoming PCC.
RESULTS ACHIEVED
Installed 1011A Tuned harmonic filter, mitigated harmonics within IEEE 519 norms, and eliminated all failures. Further recommended solutions for electronic failures of Chiron high speed CNC drives during its regeneration cycle, connected at UPS output.

Solving DC motor, VFD drive failure; Enhancing production by 25%, and Slashing energy bill by 9%

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.

Problem of electrical blast from VFD Harmonic; and a methodology for troubleshooting and increasing productivity

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.
