The Remote Safety System is an electronic system that avoids the peril of electrocutions in high-tension electrical grids. It is characterized in that each switch has a lock with a safety key, which is blocked/unblocked by a remote unit (fig. 1) , and in that it exists a remote unit (fig. 2) for every point of the electrical grid needing repairs. The remote unit has set of working cards (17) that are distributed to workers, which are returned after the repairs have finished. When the safety key is blocked inside the central unit, the working cards (17) are unblocked inside the remote unit, and vice versa. The safety key is never unblocked at the same time of the working cards . Each central unit communicates with every remote unit using modems, or transceivers, or mobile phones. |
