Division 4.2.3 Electrification system

For electrically powered interoperable trainsets, the principal interface elements between the rolling stock and the energy subsystem are defined in the energy TSI.

They are as follows:

• the maximum power that can be drawn from the catenary (Section 4.1.6.2 of this document) defined in Section 4.2.2.5 of the energy TSI,

• the maximum current that can be drawn at standstill is defined in Section 4.2.2.6 of the energy TSI,

• the voltage and the frequency of the traction supply (see Section 4.1.6.1.1) defined in Section 4.2.2.7 of the energy TSI,

• over-voltages generated on the overhead line by harmonics (see Section 4.1.6.4) defined in Section 4.3.1.7 of the energy TSI,

• electrical protection measures defined in Section 4.2.2.8 of the energy TSI,

• the distribution of the pantographs defined in Section 4.2.2.9 of the energy TSI,

• running through phase separation sections defined in Section 4.2.2.10 of the energy TSI,

• running through system separation sections defined in Section 4.2.2.11 of the energy TSI,

• adjustment of the pantograph contact defined in Section 4.2.2.12 of the energy TSI,

• power factor (see Section 4.1.6.3) defined in Section 4.3.1.3 of the energy TSI,

• regenerative braking (see Section 4.1.6.1.2) defined in Section 4.3.1.4 of the energy TSI.

The interaction between the pantographs and the catenary is of particular importance since their joint operation will ensure an uninterrupted power supply for traction and, if required, regenerative braking. These requirements shall also be observed by all combinations of trains, single trainsets as well as trainsets that are coupled in multiple. The constraints imposed by the distribution of pantographs and the quality of current collection are defined in Section 4.3.2.3 of the energy TSI.
