Earthing system
On-site measurements and analysis according to the purpose of the system, not a magic number.
Why it matters in Brazil
NR-10 requires all organisations to keep records of earthing inspection and measurement (item 10.15.3). There is no single acceptance value: the criterion depends on the purpose of the system (protection of people, lightning protection, equipment), under ABNT NBR 5410, NBR 5419-3, NBR 15751 and NBR 7117.
Every engineering design, inspection or report in Brazil must be registered with an ART (Law 6.496/1977) by a professional registered with CREA (Law 5.194/1966). NR-10 also requires every organisation to keep the electrical design and records of earthing inspection and measurement (item 10.15.3).
What it covers
- earth resistance and, where needed, soil resistivity;
- continuity of protective conductors;
- equipotential bonding.
What you receive
- report with measurement method, values and analysis;
- recommendations for corrective work;
- ART registered with CREA.
