Abstract
Systems for detecting the absence of the zero position.Addition to Patent num. 8701136 with the title "Systems for detecting the absence of the zero position. The electrical installations of B.T. are exposed to increases and decreases in network voltages due to faults in the zero position or other causes, that damage, destroy, or burn electric devices, since the electrical protections do not protect such events.Complementing said protections with these SYSTEMS, electrical devices will be protected from the above-mentioned risks.In Figure 1 of the representation of said systems, the new submodules (1.1) and (1.2) of the module (1) respectively detect the increases and decreases of the voltage due to a zero position error or other causes, notifying the module (2) of the possibility that it be transmitted to the module (3) that activates the module (4) that, among other things, with the new submodule (4.1) will cut the energy, resetting it when the possibility disappears.
