Measurement System (EMS).The requirements for Energy Measurement Systems in the relevant Technical Specifications for
Interoperability are supported by this series of European Standards.---------------------- Page: 9 ----------------------
SIST EN 50463-2:2018
EN 50463-2:2017 (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 Collecting 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.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
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. This part
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 this part of EN 50463.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).
---------------------- Page: 10 ----------------------
SIST EN 50463-2:2018
EN 50463-2:2017 (E)
The on board DHS receives, produces and stores data, ready for transmission to any
authorized receiver of data on board or on ground. The main goal of the DHS is to produce
Compiled Energy Billing Data and transfer it on an interoperable basis to an on-ground Data
Collecting System (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.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.

1 Scope
This European Standard covers the requirements applicable to the Energy Measurement Function
(EMF) of an Energy Measurement System (EMS) for use on board traction units for measurement of
energy supplied directly from/to the Contact Line system.This European Standard also gives requirements for the Current Measurement Function (e.g. current
sensor), the Voltage Measurement Function (e.g. voltage sensor) and the Energy Calculation Function
(e.g. energy meter).The Conformity Assessment arrangements for the Voltage Measurement Function, Current
Measurement Function, the Energy Calculation Function and a complete Energy Measurement
Function are also specified in this document.The standard has been developed taking into account that in some applications the EMF can be
subjected to legal metrological control. All relevant metrological aspects are covered in this part.
Figure 2 shows the flow between the functional blocks of the EMF. Only connections between the
functional blocks required by this standard are displayed.Figure 2 — EMF functional block diagram

prEN 50463-2:2015
123 Introduction
124 The Energy Measurement System provides measurement and data suitable for billing and may also
125 be used for energy management, e.g. energy saving.126 This series of European Standards uses the functional approach to describe the Energy Measurement
127 System and on-ground Data Collection Service. These functions are implemented in one or more
128 physical devices. The user of this Series of standards is free to choose the physical implementation
129 arrangements.130 — Structure and main contents of the EN 50463 series:
131 This series of European Standards is divided into five parts. The titles and brief descriptions of each
132 part are given below:133 — EN 50463-1 — General:
134 The scope of EN 50463-1 is the Energy Measurement System (EMS)
135 EN 50463-1 provides system level requirements for the complete EMS and common requirements for
136 all devices implementing one or more functions of the EMS.137 — prEN 50463-2 — Energy measuring:
138 The scope of prEN 50463-2 is the Energy Measurement Function (EMF).
139 The EMF provides measurement of the consumed and regenerated active energy of a traction unit. If
140 the traction unit is designed for use on a.c. traction systems, the EMF also provides measurement of
141 reactive energy. The EMF provides the measured quantities via an interface to the Data Handling
142 System.143 The EMF consists of the three functions: Voltage Measurement Function, Current Measurement
144 Function and Energy Calculation Function. For each of these functions, accuracy classes are specified
145 and associated reference conditions are defined. This part also defines all specific requirements for all
146 functions of the EMF.147 The Voltage Measurement Function measures the voltage of the CL system and the Current
148 Measurement Function measures the current taken from and returned to the CL system. These
149 functions provide signal inputs to the Energy Calculation Function.150 The Energy Calculation Function inputs the signals from the Current and Voltage Measurement
151 Functions and calculates a set of values representing the consumed and regenerated energies. These
152 values are transferred to the Data Handling System and are used in the creation of Compiled Energy
153 Billing Data.154 The standard has been developed taking into account that in some applications, the EMF may be
155 subjected to legal metrological control. All relevant metrological aspects are covered in this part of
156 EN 50463.157 prEN 50463-2 also defines the conformity assessment of the EMF.
158 — EN 50463-3 — Data handling:
159 The scope of EN 50463-3 is the Data Handling System (DHS) and the associated requirements of
160 Data Collection Service (DCS).---------------------- Page: 7 ----------------------
oSIST prEN 50463-2:2016
prEN 50463-2:2015
161 The on board DHS receives, produces and stores data, ready for transmission to any authorized
162 receiver of data on board or on ground. The main goal of the DHS is to produce Compiled Energy
163 Billing Data and transfer it on an interoperable basis to an on-ground Data Collection Service (DCS).
164 The DHS can support other functionality on board or on-ground with data, as long as this does not
165 conflict with the main goal.166 The DCS on-ground receives Compiled Energy Billing Data and transfer it to settlement system.
167 EN 50463-3 also defines the conformity assessment of the DHS and for the transfer of CEBD to an
168 on-ground Data Collection Service (DCS)169 — EN 50463-4 — Communication:
170 The scope of EN 50463-4 is the communication services.
171 This part of EN 50463 gives requirements and guidance regarding the data communication between
172 the functions implemented within EMS as well as between such functions and other on board units
173 where data are exchanged using a communications protocol stack over a dedicated physical interface
174 or a shared network.175 It includes the on board to ground communication service and covers the requirements necessary to
176 support data transfer between DHS and DCS including the transfer of CEBD on an interoperable
177 basis.178 EN 50463-4 also defines the conformity assessment of the communications services.
179 — EN 50463-5 — Conformity assessment:180 The scope of EN 50463-5 is the conformity assessment procedures for the EMS.
181 EN 50463-5 also covers re-verification procedures and conformity assessment in the event of the
182 replacement of a device of the EMS.183 — EMS functional structure and dataflow:
184 Figure 1 illustrates the functional structure of the EMS, the main sub-functions and the structure of the
185 dataflow and is informative only. Only the main interfaces required by this standard are displayed by
186 arrows.187 Since the communication function is distributed throughout the EMS, it has been omitted for clarity.
188 Not all interfaces are shown.---------------------- Page: 8 ----------------------

191 1 Scope
192 This draft European Standard covers the requirements applicable to the Energy Measurement
193 Function (EMF) of an Energy Measurement System (EMS) for use on board traction units for
194 measurement of energy supplied directly from/to the Contact Line system.195 This draft European Standard also gives requirements for the Current Measurement Function (e.g.
196 current sensor), the Voltage Measurement Function (e.g. voltage sensor) and the Energy Calculation
197 Function (e.g. energy meter).198 The Conformity Assessment arrangements for the Voltage Measurement Function, Current
199 Measurement Function, the Energy Calculation Function and a complete Energy Measurement
200 Function are also specified in this document.201 The standard has been developed taking into account that in some applications the EMF may be
202 subjected to legal metrological control. All relevant metrological aspects are covered in this part.
203 Figure 2 shows the flow between the functional blocks of the EMF. Only connections between the
204 functional blocks required by this standard are displayed.205
