The grounding and lightning arrester systems must comply with the NBR-5419 and, due to
the peculiarities of each installation, must be previously discussed with the VSB team.
A priori the grounding system for atmospheric discharges must be completely independent
of other loops and, also due to certain demands of some automation equipment suppliers, a
separate loop for this purpose may be needed.
