Introduction
This European Standard defines the characteristics of the on board three-phase train line which
delivers the electrical energy to the auxiliary power system. The following European Standards and
Technical Specifications refer to the defined target energy supply system in this European Standard:
CLC/TS 50534 Railway applications – Generic system architectures for onboard electric
auxiliary power systems
CLC/TS 50535 Railway applications – Onboard auxiliary power converter systems
Auxiliary converter interfaces applicable for the different options defined in
the target system architectures.
CLC/TS 50537 (series) Railway applications – Mounted parts of the traction transformer and
cooling system
Standardized products used in conjunction with traction transformers and
traction cooling systems.

)
EN 50547 Railway applications – Batteries for rail vehicles
Standardized batteries for rail vehicles and charging characteristics.
The three-phase voltage characteristics depend on the performances of the auxiliary converters which
supply the train line but also on the AC load characteristics connected to this train line. In railway
applications the available auxiliary power of the train line is generally slightly higher than the power
needed by the consumer loads, consequently tight interactions between the auxiliary power converter
system and the loads are common and have to be taken into consideration for a proper operation at
train system level.
The main objective followed by this European Standard is to define as much as possible the static
characteristics and the dynamic behaviour of the on-board three-phase supply network to assure the
best electrical compatibility with the AC loads connected to.
This European Standard is a guideline for specifying and designing the different parts of the auxiliary
power supply system namely the different auxiliary converters and the AC loads (i.e. 3 AC motors,
converters, filters, transformers, etc.) connected to the grid.
Some specific characteristics of the train line voltage may impact the reliability and the life time of the
AC loads if they are not taken into consideration during the design phase of the AC loads.
The three-phase train line voltages are never perfectly balanced and pure sinusoidal waveform
voltages, as examples:
———————
1) Under development.
o the switching of the semi-conductors within the static auxiliary converters may
generate voltage harmonics and dU/dt steps on the train line;
o the line-to-earth voltage level can vary with the auxiliary supply architecture and the
type of faults in the train line;
o a common mode voltage can appear to the star point of the 3 AC loads;
o the non linear AC loads can be a source of current harmonics, those currents
combined with the train line impedance create voltage harmonics too (mainly the input
rectifiers of certain AC loads).
In summary:
o voltage harmonics can generate noise, additional Joule or iron losses in auxiliary
motors and transformers;
o high dU/dt and the common mode voltage are at the origin of motor bearing currents
which may lead to a reduced bearing lifetime;
o voltage spikes and overvoltages may cause an early ageing of the winding insulation
materials.

1 Scope
This European Standard describes the electrical characteristics of the three-phase train line which
delivers the electrical energy from the auxiliary power converter system to the auxiliary loads.
It applies to:
o locomotive hauled passenger trains,
o electric multiple units,
o diesel electric multiple units.
This European Standard may apply to other rolling stock types (e.g. light rail vehicles, tramways,
metros, etc.) if they are not in the scope of another specific standard.
