In this paper, we propose a method to guide power frequency arcs (PFAs) and investigate the electric potential and temperature characteristics of PFAs when a negative-polarity artificial pulse (NPAP) is applied from an artificial pulse generator. Based on a two-dimensional finite-element geometrical simulation model, we acquire and analyze numerical simulation results for the electric-potential and temperature distributions in the presence and absence of NPAPs. The simulation results indicate that the NPAPs accelerate the air ionization and streamer breakdown processes, which physically affects the electric potential and temperature distributions. In addition, to determine how the NPAPs affect the PFA discharge process, we qualitatively compare the arc plasma-coupling simulation results, which suggest that the NPAPs either modify the path of the PFA or change the discharge characteristics. Moreover, we use a PFA generator to experimentally investigate the PFA voltage. These experiments enable direct observation of the PFA path produced by NPAP guides. Finally, the simulation and experimental results demonstrate that the NPAPs provide innovative, simple, and cost-effective improvements in the efficiency of arc-extinguishing devices. This technique is suitable for use with arc-extinguishing devices and has significant prospects for applications in other fields.

“…Aslani et al [26], by using the leader progression model (LPM) in 3D space together with an intelligent algorithm called teaching-learning based optimization (TLBO), propose a new method to identify vulnerable areas with the highest probability of lightning strikes. Using the TLBO algorithm, they define a new method to determine the critical current range and determine the most vulnerable points of the structure.…”

In electrical protection, there is a method of electrical protection of buildings against atmospheric discharges called the electro-geometric method or the rolling sphere method. So far, it is possible to achieve the implementation of this method graphically, that is, representing through plans and technical drawings, the protection conditions of the analyzed structure and obtaining from these graphic representations the protection parameters with the consequent errors caused by the scales and dimensions of the work plane. In the present work, a mathematical model is obtained that allows, using specific calculations, to analyze the dynamic behavior of a protection system against atmospheric discharges without worrying about the limitations given by the scales and planes. The set of equations obtained in the model allows us to determine the different parameters that define the protection system against atmospheric discharges (lightning) without depending on the graphical representation of the system's topology.
