Studies on the effects of harmonics on components and equipments have been performed and are till now in progress.
These studies, referred to power components like cables, transormers, capacitors, have conducted to proper models able to verify component capability and overload conditions. In particular also an object oriented tool has been imlemented that allows to perform the harmonic analysis of a Mv-LV system in an "user-friendly" platform named CIAO.
Studies on economical aspects of harmonic limits are aimed to evidence the link between the standard limits of harmonics and their effects obn components in trems of increased losses, and overall decreased life. The life models of components are developed taking into account thermal and electric stresses on the insulating materials.
Experimental activities are performed also on active and hybrid filters with DSP based control.
