scope:

This European Standard is intended to be used to set up the requirements for the acceptance of rolling stock on infrastructure in the field of-Coordination of protection principles between power supply and traction units, especially fault discrimination for short circuits -Coordination of installed power on the line and power demand of the trains -Coordination of traction unit regenerative braking and power supply receptivity -Coordination of harmonic behaviour. This standard deals with the definition and quality requirements of the power supply at the interface between traction unit and fixed installations. The standard specifies the interface between rolling stock and electrical fixed installations for traction, in the frame "supply system".
