Anotation

P CLC/TS 50729
This document specifies interface requirements between charging infrastructure with dedicated contact line sections and electric traction units with onboard electric traction energy storages and current collectors.
The dedicated contact line section can be separated from other contact line systems of electrified railway lines and fed separately or connected electrically and/or mechanically with contact line systems of electrified railway lines.
The charging infrastructure can be used for charging the traction units with onboard electric traction energy storages at a standstill and/or when moving.
This document covers the aspects as supply voltages and frequencies, compatibility (e.g. avoidance of (unacceptable) unbalances) with the feeding grid (national 3 AC grid), interaction between the vehicle traction/charging system and the electric traction charging power supply system, transmitting required information towards driver and/or electric traction unit, contact line system, maximum load current, contact line protection principles, electrical safety, stray current protection (in case of DC electric traction power supply systems), protection against influence on signalling systems and energy measurement and settlement.
This document applies to new charging infrastructure and/or new electric traction units with onboard electric traction energy storage.
Although this document is primarily applicable to railways it can also be partially applied to guided mass transport systems such as tramways, and elevated and underground railways.
This document does not apply to charging with a plug or connector solution or inverted current collectors mounted on the infrastructure side.
This document does not apply to electric road systems with overhead contact line systems
