Maximum Permissible Rail Potential

This article reviews the current American and European standards and codes for maximum permissible rail voltage on DC traction power systems. The principles of negative grounding device (NGD) operation and its corresponding voltage settings are also briefly discussed. The negative return portion of a modern DC railway power system, which includes the running rails (tracks), is normally isolated from earth to the maximum extent practical. The purpose of this isolation is to prevent stray DC currents from flowing through the earth and potentially causing corrosion of nearby metallic infrastructure.
