What is BS EN 50443 - Effects of EMI on pipelines about?

Electromagnetic interference (EMI) can disrupt electronic devices, equipment, and systems that are used in critical applications. BS EN 50443 discusses effects of electromagnetic interference on pipelines caused by high voltage a.c. electric traction systems and/or high voltage a.c. power supply systems. The presence of a.c. power supply systems or of a.c. electric traction systems may cause voltages to build up in pipeline 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/ electronic equipment connected to the pipeline. BS EN 50443 applies to all metallic pipelines irrespective of the conveyed fluid, e.g., liquid or gas, liable to be interfered by high voltage a.c. railway and high voltage a.c. power supply systems. BS EN 50443 is applicable to all new metallic pipelines and al...
