With
ETAP's Harmonic Analysis module, you can identify harmonic problems, reduce nuisance trips, design and test filters, and report distortion limit violations. Comprehensive load flow and frequency scan calculations are performed using detailed harmonic models and non-integer harmonic filters. Results are shown graphically, including harmonic order, harmonic spectrum plots, and harmonic waveform plots, as well as Crystal Reports. |
