The presence of ac power supply systems or of ac railway systems, in the following also indicated as ac power systems, may cause voltages to build up in pipeline systems, in the following indicated as interfered systems, running in the close vicinities of the systems above, due to one or more of the following mechanisms, i.e. to inductive coupling, conductive coupling - capacitive coupling. Such voltages may cause danger to the people, damage to the pipeline or to the connected equipment, disturbance to the electric/electronic equipment connected to the pipeline. This European Standard deals with the situations where this effect may arise and with the maximum tolerable limits of the interference effects, taking into account the behaviour of the ac power systems both: in normal operating condition and/or during the faults. This European Standard applies to all metallic pipelines irrespective of the conveyed fluid, e.g. liquid or gas, liable to be influenced by high voltage a.c. railway and high voltage a.c. power supply systems. The objective of this standard is to define the types of coupling which must be considered for operating conditions of the high voltage a.c. railway systems and high voltage a.c. power supply systems. It also defines the configurations to be considered for both the metallic pipeline - the high voltage a.c. railway systems or high voltage a.c. power systems and the limits to the voltage resulting from the coupling.This European Standard is applicable to all new metallic pipelines and all new high voltage a.c. railway systems and high voltage a.c. power supply systems and all major modifications that may change significantly the interference effect. This European Standard only relates to phenomena at the fundamental power frequency (e.g. 50 Hz or 6,7 Hz). This European Standard does not apply to - all aspects of corrosion, - the coupling from a.c. railway and power supply systems with nominal voltages less or equal 1 kV, - interference effects on the equipment through parts or apparatus not connected to the pipeline. This European Standard does not deal with costs and cost-sharing of investigations and mitigation measures
