Railway applications - Energy measurement on board trains - Part 2: Energy measuring
This draft 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 draft 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 may 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.

La présente Norme européenne couvre les exigences applicables à la fonction de mesure d’énergie (EMF) d’un système de mesure d’énergie (EMS) à utiliser à bord des unités de traction pour mesurer l’énergie directement récupérée au niveau du système de ligne de contact ou envoyée à ce dernier.
La présente Norme européenne spécifie également les exigences pour la fonction de mesure de courant (par exemple, capteur de courant), la fonction de mesure de tension (par exemple, capteur de tension) et la fonction de calcul d'énergie (par exemple, compteur d'énergie).
Les dispositions relatives à l'évaluation de la conformité pour la fonction de mesure de tension, la fonction de mesure de courant, la fonction de calcul d'énergie et l'ensemble d'une fonction de mesure d'énergie sont également spécifiées dans ce document.
Cette norme a été élaborée en tenant compte du fait que, dans certaines applications, l'EMF peut être soumise à un contrôle métrologique réglementaire. Toutes les caractéristiques métrologiques pertinentes sont traitées dans la présente partie.
La Figure 2 présente le flux entre les blocs fonctionnels de l'EMF. Seules les connexions entre les blocs fonctionnels requises par la présente norme sont représentées.

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 ----------------------

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
