Abstract

This paper describes the actual problem of inductively interfered pipelines due to traction and short circuit currents of electric railways. At first a brief overview about calculation-formulas and standards is given. Furthermore the most important limits for induced pipe potentials regarding short time- (short circuit currents) and long time interference (normal operation traction currents) of the electric railway are mentioned. In a next step the effectiveness of potential mitigation measures as earthing systems, isolating joints and compensation (reduction) conductors are shown and described mathematically.
