Abstract

I dispositivi oggetto della presente invenzione trovano impiego nel settore del monitoraggio e dell'ispezione delle opere metalliche internate (tubazioni, serbatoi, fondazioni., ecc.) e in calcestruzzo armato (viadotti, ponti, gallerie, edifici, opere civili in genere) per la misura del potenziale elettrico in presenza di correnti vaganti, provocate dagli impianti di trazione a corrente continua di treni e metropolitane. Trovano anche impiego nell'esercizio della protezione catodica, appositamente prevista per le strutture interferite per annullare gli effetti delle correnti vaganti. i dispositivi consentono in particolare di effettuare misure di potenziale eliminando i contributi spuri di caduta chimica dovuti alla presenza di correnti disperse.
