[\/vc_column_text][vc_separator][vc_column_text]Resumo:<\/strong> An experimental, non-destructive and non-invasive technique for the quick and accurate detection of the internal conditions of electromagnetic reactors for HVDC systems has been used successfully. This technique involves the application of mechanical vibrations, in scanning to find resonance frequencies and the maintenance of vibrations in these frequencies with discrete evaluation of the electrical impedance of the reactor. With the vibrations, it was identified that the unit contained moving and non-static parts as expected in healthy units. And yet, those moving parts could be moved permanently when vibrations in the resonant frequencies were applied, in safe amplitudes so as not to cause other damages.
