EN 50463-3:2017 (E)
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 and on-ground Data Collection Service. 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.
a) 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:
1) 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.
2) 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 railway
traction unit. If the traction unit is designed for use on AC traction 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. EN 50463-2 also defines all specific
requirements for all functions of the EMF.
The Voltage Measurement Function measures the voltage of the Contact Line system and the
Current Measurement Function measures the current taken from and returned to the Contact
Line 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 (CEBD).
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
EN 50463-2.
EN 50463-2 also defines the conformity assessment of the EMF.
3) EN 50463-3 — Data handling:
The scope of EN 50463-3 is the Data Handling System (DHS) and the associated requirements
of Data Collecting System (DCS).
7

---------------------- Page: 9 ----------------------

SIST EN 50463-3:2018
EN 50463-3:2017 (E)
The on board DHS receives, produces and stores data, ready for transmission to any authorized
receiver of data onboard or on ground. The main goal of the DHS is to produce Compiled
Energy Billing Data (CEBD) and transfer it to an on ground Data Collecting System (DCS). The
DHS can support other functionality on board or on ground with data (e.g. for energy
management, driver advisory systems, etc.), as long as this does not conflict with the main goal.
The DCS on-ground receives Compiled Energy Billing Data and transfer it to settlement system.
EN 50463-3 also defines the conformity assessment of the DHS and for the transfer of CEBD to
an on-ground Data Collecting System (DCS).
4) 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 reference to the on board to ground communication service and covers the
requirements necessary to support data transfer between DHS and DCS including the transfer of
CEBD on an interoperable basis.
EN 50463-4 also defines the conformity assessment of the communications services.
5) 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.
b) 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 widely omitted for
clarity, except for the train to ground communication. Not all interfaces are shown.

93 unit. If the traction unit is designed for use on a.c. traction systems the EMF also provides measurement
94 of reactive energy. The EMF provides the measured quantities via an interface to the Data Handling
95 System.
96 The EMF consists of the three functions: Voltage Measurement Function, Current Measurement Function
97 and Energy Calculation Function. For each of these functions, accuracy classes are specified and
98 associated reference conditions are defined. EN 50463-2 also defines all specific requirements for all
99 functions of the EMF.
100 The Voltage Measurement Function measures the voltage of the Contact Line system and the Current
101 Measurement Function measures the current taken from and returned to the Contact Line system. These
102 functions provide signal inputs to the Energy Calculation Function.
103 The Energy Calculation Function inputs the signals from the Current and Voltage Measurement Functions
104 and calculates a set of values representing the consumed and regenerated energies. These values are
105 transferred to the Data Handling System and are used in the creation of Compiled Energy Billing Data.
106 The standard has been developed taking into account that in some applications the EMF may be
107 subjected to legal metrological control. All relevant metrological aspects are covered in EN 50463-2.
108 EN 50463-2 also defines the conformity assessment of the EMF.
109 — prEN 50463-3 — Data handling:
110 The scope of prEN 50463-3 is the Data Handling System (DHS).
111 The on board DHS receives, produces and stores data, ready for transmission to any authorized receiver
112 of data on board or on ground. The main goal of the DHS is to produce Compiled Energy Billing Data and
4

oSIST prEN 50463-3:2016
prEN 50463-3:2015
113 transfer it to an on ground Data Collection Service (DCS). The DHS can support other functionality on
114 board or on ground with data, as long as this does not conflict with the main goal.
115 prEN 50463-3 also defines the conformity assessment of the DHS.
116 — EN 50463-4 — Communication:
117 The scope of EN 50463-4 is the communication services.
118 This part of EN 50463 gives requirements and guidance regarding the data communication between the
119 functions implemented within EMS as well as between such functions and other on board units where
120 data are exchanged using a communications protocol stack over a dedicated physical interface or a
121 shared network.
122 It includes the on board to ground communication service and covers the requirements necessary to
123 support data transfer between DHS and DCS.
124 EN 50463-4 also defines the conformity assessment of the communications services.
125 — EN 50463-5 — Conformity assessment:
126 The scope of EN 50463-5 is the conformity assessment procedures for the EMS.
127 EN 50463-5 also covers re-verification procedures and conformity assessment in the event of the
128 replacement of a device of the EMS.
129 — EMS functional structure and dataflow:
130 Figure 1 illustrates the functional structure of the EMS, the main sub-functions and the structure of the
131 dataflow and is informative only. Only the main interfaces required by this standard are displayed by
132 arrows.
133 Since the communication function is distributed throughout the EMS, it has been omitted for clarity. Not all
134 interfaces are shown.
