CARLOS, Quinatoa,; DAMIAN, Albán,; XAVIER, Proaño,  and  LUIS, Camacho,. Development of an Algorithm for Protection against Atmospheric Discharges in Buildings. Rev Politéc. (Quito) [online]. 2025, vol.55, n.1, pp.51-60. ISSN 2477-8990.  https://doi.org/10.33333/rp.vol55n1.05.

The research concentrates on the algorithmic progress aimed at the protection against atmospheric impacts on structures using the rolling sphere technique. The methodology starts with the collection of project details, covering the ceramics level and structural measures. The risk elements are evaluated in a risk assessment software to find some scenarios, such as loss of life, service suspension and property damage. If necessary, corrections are managed; otherwise, protection strategies are implemented. This includes determining soil resistivity in accordance with IEEE 81, applying the rolling sphere technique of IEC 62305-3, and complying with the grounding system principles in IEEE 142 and IEEE 80. To analyze atmospheric discharges within a protected structure, electrical equivalents are calculated for mesh conductors, copper welding rods, and horizontal and vertical conductors. The results are used in an Atpdraw circuit linked to Python, which generates plots of the current waveforms for various protective subsystems. The risk elements are reevaluated to ratify the procedure. The verification is based on the idea that the margin of error converges to zero when inputting data from exercises that comply with standards such as IEC and IEEE.
