Read also the Identifying Power Shelves section. This position-versus-ID number relationship is very important for the correct monitoring of the mains three phases.

In other words. To achieve a more controlled ID assignment. It is common to use the removal between connecting rods equal or superior to the length of the 8 connecting rod [ 8 ].

The chain that enters the grounding system is dispersed in the ground,generating electric tensions. In this in case, so that the possibility of dispersion of the connecting rod is used fully is necessary to dletricas it outside the zone of dispersion of the other, or either, in the region of null potential. One has had the concern about distributing the workmanships amongst the diverse quarters of the region. When accidents occur because of electrical shock, there is a considerable probability for it to become fatal.

Livro instalacoes eletricas helio creder em pdf livros no. This instrument had as greater objective the identification of relative non-conformity to the electric installations that could generate danger to the user, the proper installation and the patrimony, especially as for the systems of protection against electric shocks.

These numbers, however, are on this side of what is expected to find instakaoes in the considered companies of great transport and demonstrates that the great majority of the enterprises possesses the equipment filled with earth with the elements electrodes, connections and conductors adjusted but they display imperfections in other important items of the norm many times due to knowledge or efficient fiscalization.

However, in practice it is not common to use very long connecting rods, which are not simple to embed in the ground. The NBR norm [5] establishes the guidelines to the dimensioning and installation of the equipotentialization systems. In addition to this norm recently came into force the law n. Equi-potentialization of the electrical installations.

When accidents occur because of electrical shock, there is a considerable probability for it to become fatal. When approaching the subject Protection against Electric Instalaoees, such norm establishes two fundamental principles which are key-ring for the understanding of the rules, procedures and norms and, consequently, to the effectuation of the hazards control inherent to the handling, operation and intervention in electrical webs. For identification of the electric risks at the work sites, a specific protocol, based in previous studies was elaborated and the current law NR 10, NR 18 and NBR Basic specifications for the grounding system.
