High Safety and Continuity of Operation of Low Voltage Plants

The aim of this work is to show a new device for the absolute protection and continuity of service of low voltage electrical systems. The device is entirely electronic and digital, and this achieves much greater speed and flexibility compared to electromechanical ones. The latter, guided by the Norm 64/08, disconnect the entire system whenever they encounter dangerous situations for people or for the system. The proposed device instead performs complete safety for users and system and achieves the continuity of operation of the electrical system, which is never disconnected. The new device can replace the current electromechanical devices and can be installed mainly for those work environments in which the continuity of service is essential such as, for example, the special work environments of airports that require compliance with high safety standards. The installation of the new device is compatible with the permanence of the traditional electromechanical devices that however will never intervene.
