An opto-electronic system for the acquisition of signals indicating the presence of a voltage and its phase in distribution boards, and generally in any medium voltage or high voltage installation by means of the use of optical fibers of PVC with consequent elimination of the risks of electrocution and of the problems of transmission of the signals themselves. The system employs an electro-optical convertor connected to a capacitive shunt for generating light signals indicative of the presence of a voltage and the phase angle on a conductor without making use of auxiliary sources of supply. The system can also be integrated in an insulating rod for checking overhead conductors.
