Simulation of Electromagnetic Fields Occurring at Intersection of Traction Networks and Multicircuit Power Lines [PDF]

E3S Web of Conferences, 2020
Traction networks (TN) 25 kV generate higher electromagnetic fields (EMF) with frequency 50 Hz, whose strengths at a standardized height of 1.8 m, as a rule, do not exceed the permissible norms for electrical personnel.
