“…There are many approaches for the calculation of stray currents in railway traction, depending on the type of section, load, and other In this case, according to Kirchhoff's first law, the currents in sections ab, bc, cd, and de of the catenary (i.e., equivalent contact wire) will be equal to I c1 = 835.6 A, I c2 = 626.7 A, I c3 = 417.8 A, and I c4 = 208.9 A. At the same time, according to different publications [33][34][35][36], the proportion of currents flowing in the track circuits of the AC electric traction system could vary in a very wide range up to 50-60% of the current in the catenary. The nature of stray (earth) return current transmission in itself is a complicated enough topic because of different factors.…”

“…However, overvoltage and overcurrent protections are not considered. Another work proposes a EMTP model to determine the current distribution in the different wires of the overhead feeding system as well as the rails [110]. This current distribution affects to the couplings with the surrounding metallic structures.…”
