Bibliography

Defines requirements for the compatibility of rolling stock with infrastructure particularly in relation to: - 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 the power demand of trains; - co-ordination of traction unit regenerative braking and power supply receptivity; - co-ordination of harmonic behaviour.
