Railway applications - Energy measurement on board trains - Part 2: Energy measuring
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 may be subjected to legal metrological control. All relevant metrological aspects are covered in this part.

Ta evropski standard zajema zahteve za funkcijo merjenja energije (EMF) sistema merjenja energije (EMS), ki se uporablja na vlakovnih kompozicijah za merjenje energije, dovajane neposredno iz sistema kontaktnega vodnika ali vanj. Ta evropski standard določa tudi zahteve za funkcijo merjenja toka (npr. tokovni senzor), funkcijo merjenja napetosti (npr. napetostni senzor) in funkcijo izračuna energije (npr. števec energije). V tem dokumentu so navedeni tudi načini ugotavljanja skladnosti funkcije merjenja napetosti, funkcije merjenja toka, funkcije izračuna energije in celotne funkcije merjenja energije. Standard je bil pripravljen ob upoštevanju dejstva, da se lahko pri nekaterih načinih uporabe funkcije merjena energije izvaja zakonit metrološki nadzor. Ta del zajema vse zadevne metrološke vidike.

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 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.
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.
---------------------- Page: 8 ----------------------
SIST EN 50463-2:2013
- 7 - EN 50463-2:2012
EN 50463-3 also defines the conformity assessment of the DHS.
EN 50463-4 – Communication
The scope of EN 50463-4 is the communication services.
Part 4 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.
Because the communication function is distributed throughout the EMS, it has been omitted for clarity.
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 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.
