General protectors increases or decreases in voltage neutral failures or other causes.

摘要

Addition to Patent P9802627 general protectors increases or decreases voltage failure neutral or other causes. BT electrical installations are subject to ups and downs of tension, which break down their receivers, without the current protections protect them from such anomalies. Fig. 18, with the module (1) detects the voltage acting on the module (2) that the signals and the (3), which activates the module (5) by opening the contacts (6) which cuts power during overvoltage. With the module (1.1) detects the undervoltage, by acting on the module (2.1) the signals and on (3.1), which activates the module (5) by opening the contacts (6) which cuts power during brownout. When anomalies disappear the signs are turned off reestablishing the service. The module (4) feeds (5).
