General protectors against voltage increases and decreases due to zero position errors or other causes

摘要

General protectors against voltage increases and decreases due to zero position errors or other causes.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 PROTECTORS, electrical devices will be protected from the above-mentioned risks.The protector in Figure 1, in which the module (1) detects the increase and decrease of the voltage due to a zero position error or other causes, the module (2) is notified of the possibility, transmitting it to module (3), which will order the opening of module (3.1), cutting the energy in the circuit that it protects until the situation is normalised, and only the latter resets the service.
