Deleterious effects on electrical equipment by harmonics:
1. Capacitor bank failure because of reactive power overload, resonance, and harmonic amplification, Nuisance tripping operation.
2. Excessive losses, heating, harmonic torques, and oscillations in induction and synchronous machines, which may give rise to torsional stresses.
3. Increase in negative sequence current loading of synchronous generators, endangering the rotor circuit and windings.
4. Generation of harmonic fluxes and increase in flux density in transformers, eddy current heating, and consequent derating.
5. Overvoltages and excessive currents in the power system, resulting from resonance.
6. Derating of cables due to additional eddy current heating and skin effect losses. A possible dielectric breakdown.
WAVEFORMS offers a unique solutions which are best in power quality units with a proven performance for lowering harmonics caused by variable frequency drives (vfds), power supplies furnace & ups. Our products are rugged, robust, reliable
& cost effective, one works on both the line (input) side and load (output) side to give you an easy solution that reduces nuisance tripping, reduces harmonic distortion, minimizes power losses & maximizes productivity.
