Phase current and waveform before AHF
Phase current and waveform after AHF
Harmonic current value before AHF
Harmonic current value after AHF
1）After active harmonic filter operating, the waveform of both voltage and current had been improved. The harmonic content also been widely reduced. The THDv was reduced from 2.7% to 0.8%. The THDi was reduced from 43.5% to 4.2%.
2）After compensation, the power factor had been reached補償to more than 0.95. This result showed the integrated compensation ability to harmonic and reactive power of our active harmonic filter.
3）The power loss had been reduced, the operation environment of equipment become much safer.
