Influence of the scenario in the calculation of electric field intensification factor Part I: 2D approximation

Nowadays, the so called ´Electric Field Intensification Factor´, usually noted as Ki, is evaluated with classical concepts or formulations employed in many applications related with partial and complete electric discharges. There are also engineering applications, such as lightning protection, where usually there is more than one object within the scenario and, evidently, those objects modify the electric field pattern and consequently this Ki, should be corrected considering this influence in order to evaluate properly the real conditions reproduced in the scenario under evaluation. In this paper, some Finite Element Method (FEM) simulations have been done to get a dataset to make a regression thus obtaining an ´environmental correction factor´, which will be a function of the dimensions of the main and secondary structures and the distance between them.
