23、. This European Standard gives limits relevant to the electromagnetic interference produced by high voltage a.c. railway and power supply systems on metallic pipelines. Limits are relevant to the interference which can be tolerated on the metallic pipeline, by the equipment connected to it and by pe
24、rsons working on them or in contact with them. This European Standard indicates the electromagnetic interference situations to which the limits must be related. Suggestions concerning the interference situations to be examined are given in Annex A. Suggestions concerning the appropriate calculation
25、methods are given in Annex B. Suggestions concerning the appropriate measurement methods are given in Annex C. Suggestions about the use of mitigation measures are given in Annex D. Suggestions for management of interference are given in Annex E. The following dates are fixed: latest date by which t

28、n or networking permitted without license from IHS-,-,-BS EN 50443:2011 5 EN 50443:2011 1 Scope The presence of a.c. power supply systems or of a.c. electric traction systems (in this standard also indicated as a.c. power systems) may cause voltages to build up in pipeline systems, (in this standard
29、 indicated as interfered systems) running in the close vicinity, due to one or more of the following mechanisms: inductive coupling, conductive coupling, capacitive coupling. Such voltages may cause danger to persons, damage to pipelines or connected equipment or disturbance to the electrical/ elect
30、ronic equipment connected to the pipeline. This European Standard deals with the situations where these effects may arise and with the maximum tolerable limits of the interference effects, taking into account the behaviour of the a.c power systems both in normal operating condition and/or during fau
31、lts. NOTE In the worst case, the pipe may not disperse current to ground. As a consequence, the prospective touch voltage coincides with the interference voltage. This European Standard applies to all metallic pipelines irrespective of the conveyed fluid, e.g. liquid or gas, liable to be interfered
32、by high voltage a.c. railway and high voltage a.c. power supply systems. The objective of this standard is to establish: the procedure for evaluating the electromagnetic interference; the interference distance to be considered; the types of coupling to be considered for operating and fault condition
33、s of the high voltage a.c. electric traction systems and high voltage a.c. power supply systems; the configurations to be considered for both metallic pipeline and high voltage a.c. electric traction systems or high voltage a.c. power systems; the limits of the voltages due to the electromagnetic in
34、terference; information on interference situations, calculation methods, measuring methods, mitigation measures, management of interference. This European Standard is applicable to all new metallic pipelines and all new high voltage a.c. electric traction systems and high voltage a.c. power supply s
35、ystems 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 16,7 Hz). This European Standard does not apply to: all aspects of corrosion, the coupling from a.c. railway an
36、d power supply systems with nominal voltages less than or equal to 1 kV, interference effects on the equipment not electrically connected to the pipeline. 2 Normative references The following referenced documents are indispensable for the application of this document.
