The Brazilian electrical sector is in a key moment in which global requirements, particularly for sustainability \u2013 in the broad sense of the term \u2013 determine that innovation is needed to bring to the field solutions that contribute to greater efficiency and security in energy generation and distribution. <\/p>\n\n\n\n

Digitalization<\/a> of the electrical distribution grid is a solution for meeting these demands, by preparing the system for increased demand and placing the sector at the vanguard in the adoption of innovative systems. <\/p>\n\n\n\n

The major trends include technologies for automation of electrical distribution systems. This involves a series of concepts and technologies that offer greater stability, reliability and protection to networks, both for utilities and consumers. Keep reading and learn more!<\/p>\n\n\n\n

How automation of electrical distribution systems contributes to security on a grid<\/h2>\n\n\n\n

Automation of electrical distribution systems involves a group of factors and its main objective is to protect a grid, especially to guarantee communication among the various applications of the system. <\/p>\n\n\n\n

One of the major gains is the high capacity of an automated system to identify faults using real time sharing of data about equipment on the grid. This allows a more efficient response to these events, allowing improved protection for the system. <\/p>\n\n\n\n

Moreover, automation offers benefits in terms of service at the point of the line, that is, for consumers, to improve management of restoration of the grid and thus reduce the average service time. This is all done automatically and intelligently, which assures that both the interruption and the reconnection are faster and lead to less losses. <\/p>\n\n\n\n

Another point that cannot go unnoticed is the possibility to reduce costs. After all, greater agility in identifying and resolving mistakes, combined with better management of the grid in real time allows more efficient and better focused operation. <\/p>\n\n\n\n

That is, by means of automation, the system identifies precisely where is the fault, how to resolve it and automatically places in practice contention measures to mitigate risks.<\/p>\n\n\n\n

Logic Selectivity<\/h3>\n\n\n\n

Logic selectivity is based on the concept that to be reliable an electrical system must be selective, that is, when a failure occurs, the system only selects the equipment closest to the mistake. <\/p>\n\n\n\n

Thus, logic selectivity makes the time of protective action independent from the point of the fault, because it allows isolating the smallest portion of the system in the shortest possible time. <\/p>\n\n\n\n

This is done by sending blocking signals that impede the action of devices outside the region of the fault. Thus, in the case of events, all the components on the grid that sense the fault signal send an alert to the closest devices upstream, allowing only those that are closest to act. <\/p>\n\n\n\n

As a result, logic selectivity allows: <\/p>\n\n\n\n
