A study of Protection for electrical corrosion by stray current in DC railway system

직류전기철도시스템에서의 누설전류에 의한 전식방지에 대한 연구

The stray current(leakage current) in DC railway system like as Metro Subway and LRT system happens electrical corrosion on theses superstructure facilities and also underground facilities that causes the public property losses. we must study and establish on the theoretical concept and concrete phenomena for electrical corrosion, In the construction period we intend to review and find out a lot of solution to minimize theses losses. we must investigate, measure and analysis natural atmosphere of these facilities locations to present a maintenance management guide for the upcoming operation stage.
