Magnetic Levitation motor harmonics

Turbo energy Ltd, Paiyanoor

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

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.
Installed 831A main transformer and a 88A chiller end harmonic filters, mitigated harmonics within IEEE 519 norms, and eliminated all failures.
