Railway applications - Fixed installations - Part 2: Protective provisions against the effects of stray currents caused by d.c. traction systems

Scope

This standard specifies requirements for protective provisions against the effects of stray currents which result from the operation of d.c. traction systems. As experience for several decades has not shown evident corrosion effects from a.c. traction systems and actual investigations are not completed, this standard only deals with stray currents flowing from a d.c. traction system. This standard applies to all metallic fixed installations which form part of the traction system, and also to any other unrelated metallic components located in any position in the earth, which may carry stray currents resulting from the operation of the railway system. This standard applies to all new electrification of a d.c. railway system. The principles may also be applied to existing electrified systems where it is necessary to consider the effects of stray currents. 94
