The geoelectrical study of the subsoil makes it possible to establish the optimum configuration of the earthing system to be designed. The ground resistivity measurement makes it possible to determine the layout, depth, number and type of elements necessary according to safety and functional requirements.

The general earthing system connects the different parts of an electrical installation with the surface conductor of the Earth to guarantee security and functionality.

In an electrical installation, the soil itself provides equipotentialization for all of the metallic parts so that there are no differences in potential between each other. This is carried out in order to guarantee the safety of people and equipment from any possible defects in the actual facilities.

Aplicaciones Tecnológicas puts its more than 35 years of experience to offer free webinars aimed at professionals involved in the design of lightning protection systems and safety against electrical storms, design and implementation of earthing and surge protection systems.

A recent judgment in Brazil has created case law on the liability of farm owners for the death by lightning impact of a worker in 2019, by ordering him to continue work in the field during a thunderstorm. Subjective decision-making, based on criteria of the probability of the impact of a lightning strike or on traditional methods puts people’s lives at risk. On the contrary, as stated in the Brazilian standard ABNT NBR 16785 on thunderstorm detection, some systems make it possible to objectify the decision and save workers and assets from the imminent risk of a lightning strike.
