Abstract :
This paper describes an algorithm for the calculation of the per unit length parameters of a multiconductor line with earth return inside a tunnel in the quasi-static range. The main application of this work is the characterization of an electrified railway line, located inside a generic tunnel, as a source of electromagnetic interference on structures like telecommunication cables, metallic pipes and ducts
