Over the years, numerous fires have occurred, both in homes and premises, due to defects in the electrical installation that produced an electric arc, or due to the poor condition of the insulation, which over time ages and loses properties. , or a possible bad installation. Under these conditions, disruptive discharges generated by gas ionization can occur as a consequence of an accidental electrical connection between two surfaces of different potential, causing an electric arc.
When an electric arc occurs, a flow of electrical charges occurs and a large release of energy and dangerous substances occurs. During the discharge time, a very intense luminosity and a large release of heat are produced. Both phenomena can be extremely destructive due to exposure to excessive temperature rise, which can cause a fire if not extinguished in time.
For these cases, the AFDD has been designed, a device designed for homes, commercial premises and industry with high fire risk. When the electric arc occurs, due to the low intensity of current that circulates through it, it is very likely that the automatic switches will not detect it since the intensity value is lower than the overcurrent protection values that the switches have..
The AFDD is capable of detecting the possible appearance of an electric arc in the different circuits connected to it, both in series and in parallel, as well as protecting against overloads and short circuits, as well as indicating, specifically, whether the electric arc fault has occurred. produced independently of the overload or short circuit so that once it is extinguished, an inspection of the installation can be carried out to detect where the electric arc was formed and prevent its reappearance.
