In overhead transmission lines, stranded conductors are often used to reduce the inductance and increase the mechanical strength. Transmission lines are subjected to power frequency and lightning flashovers which need careful analysis of electric and critical fields before erection. The dependence of maximum electric field intensity under power frequency and lightning impulse, for stranded conductors of different strands using Aluminum conductor steel reinforced (ACSR) has been analyzed in this work. It involves field computation ofstranded conductors which have different numbers of strands. Conductors of 1,7,19 and 37 strands have been analyzed. Field computation is achieved by the Finite element method in COMSOL Multiphysics. 04 30 2025 04 30 2025 1 5 CC-BY-NC-ND 4.0 10.35940/BEIESP.CrossMarkPolicy www.ijitee.org true International Journal of Innovative Technology and Exploring Engineering (IJITEE) Blue Eyes Intelligence Engineering and Sciences Publication (BEIESP) Based on my understanding, this article has no conflicts of interest.
