DC-electrified traction systems are a potential source of stray current that may corrode internal and external structures and installations. The stray current intensity depends on several factors (traction current, rail insulation, concrete mat and piers resistance), that are accounted for in the proposed model. The case of a viaduct and a victim-buried pipeline is considered in detail, and the estimated impressed voltage on the pipe is compared successfully with experimental results.

Abstract
DC-electrified traction systems are a potential source of stray current that may corrode internal and external structures and installations. The stray current intensity depends on several factors (traction current, rail insulation, concrete mat and piers resistance), that are accounted for in the proposed model. The case of a viaduct and a victim-buried pipeline is considered in detail, and the estimated impressed voltage on the pipe is compared successfully with experimental results.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
