Bibliography

IEC 62313:2009 is intended to be used to set up the requirements for the acceptance of rolling stock on infrastructure in the field of:
- co-ordination of protection principles between power supply and traction units, especially fault discrimination for short-circuits;
- co-ordination of installed power on the line and power demand of the trains;
- co-ordination of traction unit regenerative braking and power supply receptivity;
- co-ordination of harmonic behaviour.
