Introduction
The Energy Measurement System provides measurement and data suitable for billing and may also be used
for energy management, e.g. energy saving.
This series of European Standards uses the functional approach to describe the Energy Measurement
System. These functions are implemented in one or more physical devices. The user of this Series of
standards is free to choose the physical implementation arrangements.
Structure and main contents of the EN 50463 series
This series of European Standards is divided into five parts. The titles and brief descriptions of each part are
given below:
EN 50463-1 – General
The scope of EN 50463-1 is the Energy Measurement System (EMS).
EN 50463-1 provides system level requirements for the complete EMS and common requirements for all
devices implementing one or more functions of the EMS.
EN 50463-2 – Energy measuring
The scope of EN 50463-2 is the Energy Measurement Function (EMF).
The EMF provides measurement of the consumed and regenerated active energy of a traction unit. If the
traction unit is designed for use on a.c. traction supply systems, the EMF also provides measurement of
reactive energy. The EMF provides the measured quantities via an interface to the Data Handling System.
The EMF consists of the three functions: Voltage Measurement Function, Current Measurement Function
and Energy Calculation Function. For each of these functions, accuracy classes are specified and associated
reference conditions are defined. This part also defines all specific requirements for all functions of the EMF.
The Voltage Measurement Function measures the voltage of the CL system and the Current Measurement
Function measures the current taken from and returned to the CL system. These functions provide signal
inputs to the Energy Calculation Function.
The Energy Calculation Function inputs the signals from the Current and Voltage Measurement Functions
and calculates a set of values representing the consumed and regenerated energies. These values are
transferred to the Data Handling System and are used in the creation of Compiled Energy Billing Data.
The standard has been developed taking into account that in some applications, the EMF may be subjected
to legal metrological control. All relevant metrological aspects are covered in this part of EN 50463.
EN 50463-2 also defines the conformity assessment of the EMF.
EN 50463-3 – Data handling
The scope of EN 50463-3 is the Data Handling System (DHS).
The on board DHS receives, produces and stores data, ready for transmission to any authorised receiver of
data on board or on ground. The main goal of the DHS is to produce Compiled Energy Billing Data and
transfer it to an on-ground Data Collection Service (DCS). The DHS can support other functionality on board
or on-ground with data, as long as this does not conflict with the main goal.
EN 50463-3 also defines the conformity assessment of the DHS.

SIST EN 50463-1:2013
- 5 - EN 50463-1:2012
EN 50463-4 – Communication
The scope of EN 50463-4 is the communication services.
This part of EN 50463 gives requirements and guidance regarding the data communication between the
functions implemented within EMS as well as between such functions and other on board units where data
are exchanged using a communications protocol stack over a dedicated physical interface or a shared
network.
It includes the on board to ground communication service and covers the requirements necessary to support
data transfer between DHS and DCS.
EN 50463-4 also defines the conformity assessment of the communications services.
EN 50463-5 – Conformity assessment
The scope of EN 50463-5 is the conformity assessment procedures for the EMS.
EN 50463-5 also covers re-verification procedures and conformity assessment in the event of the
replacement of a device of the EMS.
EMS functional structure and dataflow
Figure 1 illustrates the functional structure of the EMS, the main sub-functions and the structure of the
dataflow and is informative only. Only the main interfaces required by this standard are displayed by arrows.
Since the communication function is distributed throughout the EMS, it has been omitted for clarity. Not all
interfaces are shown.

4 Requirements
4.1 General
Clause 4 of this document describes the requirements of an EMS.
4.2 gives system level requirements for the complete EMS.
4.3 gives common requirements for all devices implementing one or more functions of the EMS.
4.2 System level requirements
If an EMS has any functions which are additional to those specified in EN 50463, then these functions shall
not:
• affect the accuracy,
• degrade the operation of the EMS, and
• influence the production and storage of CEBD and CEBD-related data.
Any changes to configuration shall be logged in the EMS, and the device marking and stored information
shall also be updated.
4.2.1 Accuracy
The energy measurement accuracy is defined by the functions of the EMF and shall be determined in
accordance with EN 50463-2.
4.2.2 EMS operation and power supply
The EMS shall be fully operational whenever energy flows from or to the CL.
Any part of the EMS powered by an auxiliary power supply, shall be compatible with the requirements of
EN 50155:2007 regarding power supply characteristics.
The rated power supply voltage and maximum power consumption of the EMS shall be stated.
4.2.2.1 Power-up
The EMS shall achieve operational status and be ready to measure energy within 60 s of application of
power to the EMS.
NOTE 1 The application of power to the EMS is an installation design consideration.
NOTE 2 The 60 s maximum time limit has been selected because the power-up procedure for traction units typically
requires several minutes to elapse between switching on the vehicles ancillary supplies and any significant amount of
energy being drawn from the CL.

---------------------- Page: 12 ----------------------

SIST EN 50463-1:2013
- 11 - EN 50463-1:2012
4.2.2.2 Power-down
In the event of intentional loss of power to the EMS, no CEBD and other data shall be lost.
Unintentional loss of power shall not affect data stored in the EMS.
NOTE The EMS could include a procedure for transmitting all unsent CEBD to DCS as part of a planned power-down
procedure of the EMS. This can help to support timely data processing on-ground.
4.2.3 EMS measuring input
4.2.3.1 Installation point of the VMF and CMF
The position of the VMF(s) and CMF(s) in the power circuit shall ensure that all active and reactive energy
taken from and returned to the CL is measured.
NOTE Devices consuming small quantities of energy (e.g. high impedance voltage monitoring/detection devices,
insulators etc.) are not considered significant and their consumption need not be measured by the EMS.
4.2.3.2 Characteristics of traction supply system
The ratings of the EMS voltage and current measuring inputs shall be selected in accordance with
EN 50463-2 taking into account the intended traction energy supply system and traction unit rated current.
4.2.4 Data handling
4.2.4.1 Traction supply system change
An EMS (one or multiple) shall cover all traction supply system types that the traction unit can operate on.
If an EMS is used for more than one traction supply system, it shall continue to function correctly when
changing between systems, and log each change of traction supply system. Changes between 600 V and
750 V d.c. traction supply systems do not need to be logged.
NOTE 1 This may be achieved directly by the EMS or by input signals from the traction unit.
NOTE 2 If voltage detection is used to detect traction supply system change, overvoltages above U , in accordance
max2
with EN 50163:2004, and voltage drops below U could cause a detection of a system change.
min2
The EMS shall measure energy consumption within 1 s of the change to the new traction supply system.
4.2.4.2 Consumption point ID
Each EMS shall be assigned a unique consumption point ID.
NOTE The EMS can carry a fictitious CPID until such time as the EMS is commissioned into commercial use. The
process of assigning the correct CPID to a specific EMS needed when bringing it into commercial use, is out of the scope
of this standard.
The consumption point ID shall be stored in non-volatile memory of the EMS. Security procedures shall be
implemented to prevent unauthorised changes to the consumption point ID.
4.2.5 RAMS
4.2.5.1 Reliability
Reliability requirements shall be in accordance with EN 50155:2007, 6.1.1. Reliability figures and calculation
methods are a matter of agreement between the supplier and purchaser.

4.2.5.3 Maintainability
Maintainability requirements shall be in accordance with EN 50155:2007, 6.3, 6.4 and 6.5.
Further requirements, if any, shall be agreed between the supplier and purchaser.
4.2.5.4 Safety
The EMS shall be designed, manufactured and installed on board the traction unit in such a way that it is
safe in normal use and under normal conditions, in particular to ensure
• personal safety against electric shock in accordance with EN 50153,
• personal safety against effects of excessive temperature in accordance with EN ISO 13732-1, and
• protection against spread of fire (guideline can be found in CEN/TS 45545-2 and CLC/TS 45545-5).
NOTE When considering personal safety (electric shock risk), CL failure is a credible failure condition. This may pose a
risk if a live part of the CL comes into direct contact with an exposed part of the EMS, or an exposed device connected
directly to the EMS (e.g. roof mounted devices containing VMF, CMF or antenna).
4.3 Device level requirements
4.3.1 Marking and availability of essential data
4.3.1.1 Marking
Each device of the EMS shall be permanently and clearly marked, internally or externally, with the following
information. If the marking is internal it shall be visible from the outside of the device.
Marking shall include:
a) the manufacturer’s name or trade mark;
b) the designation of equipment type;
c) the serial number and date of manufacture;
NOTE It is permitted to integrate the date of manufacturing into the serial number.
The device marking may contain other additional information.
4.3.1.2 Availability of essential information
The following information shall be available in a format (e.g. hardcopy or electronic) agreed between supplier
and purchaser:
a) data identifying all devices in the EMS and the EMS configuration;
b) all information necessary to specify the characteristics and control the behaviour of each device of the
EMS;
c) any special installation requirements necessary to ensure safe and correct operation (e.g. any
requirements related to personal safety, installation environmental constraints to ensure correct
operation, etc.).
