Railway Power Supply

Improving the Safety and Availability of Traction Power Supply Systems

Special components for the DC feeding systems ensure faultless emergency shutdown to avoid severe damages to the system and possible injury of people. Preventing unnecessary disruptions to operation with accurate fault detection has a considerable impact on rail traffic and availability of the system.

Worldwide, there are more than 7 billion dollars a year invested in permanently installed electrical equipment of railway networks. A considerable investment of this money will be spent on public transportation systems, where above average growth is expected over the coming years[1]. One reason for this is the increasing traffic congestion in metropolitan areas.
Another reason is the wish to achieve political aims concerning climate protection and conservation of natural resources.
Both are good reasons to promote the investments in public transportation systems.

Railway lines are installed or extended and existing networks are re-equipped with state-of-the-art technology. Uninterrupted and safe operation is of high priority for the operator of a public transportation system.
Therefore, high demands are placed on the technical equipment.
