Such effects are sporadically related to harmonic distortion while the conventional remedy for this problems is passive filter, but this have certain limitations like Filtering efficiency depends on network parameters, danger for overloading filter components, difficult to extend, possibilityof resonance, multiple branches required for filtering more than one harmonic and hence large space requirement. Hence, Shreem has SPF-PCE series of Active harmonic filter called “Power Conditioning Equipment” have much higher levels of efficiency in harmonic cleaning and having flexibility of installation.
