Abstract

Sistema opto-elettronico (1) per l'acquisizione dei segnali di presenza tensione e fase in quadri (QT), e genericamente in tutte le installazioni, a media tensione MT o ad alta tensione AT mediante l'utilizzo di fibre ottiche (F1, F2) in PVC con conseguente eliminazione dei rischi di elettrocuzione e delle problematiche di trasmissione dei segnali stessi. Il sistema (1) impiega un convertitore elettro-ottico (EO), collegato ad un derivatore capacitivo (DC), per generare segnali luminosi indicativi di presenza tensione e dell'angolo di fase su un conduttore (FT) senza avvalersi di sorgenti di alimentazione ausiliarie. Il sistema (1) può anche essere integrato in un'asta isolante (AIS) per il controllo di conduttori aerei (FT).(Figura 2)Opto-electronic system (1) for the acquisition of voltage and phase presence signals in switchboards (QT), and generally in all installations, medium voltage MT or high voltage AT through the use of optical fibers (F1, F2) in PVC with consequent elimination of the risk of electrocution and of the problems of transmission of the signals themselves. The system (1) uses an electro-optical converter (EO), connected to a capacitive shunt (DC), to generate luminous signals indicating the presence of voltage and the phase angle on a conductor (FT) without using power sources auxiliary. The system (1) can also be integrated into an insulating rod (AIS) for the control of overhead conductors (FT). (Figure 2)
