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.
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.
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.
---------------------- Page: 6 ----------------------
SIST EN 50463-3:2013
- 5 - EN 50463-3:2012
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.

4.1 General
The requirements in EN 50463-1:2012, Clause 4 apply to any device containing one or more functions of the
DHS where applicable. EN 50463-3 defines additional requirements specific to the DHS and basic
requirements for the DCS.
The DHS shall comply with the following requirements except for 4.12.
The DCS shall comply with the requirements in 4.12 only.
4.2 Time data
4.2.1 Source
The DHS shall produce time data using an internal time source (clock).
4.2.2 Reference time source
The internal time source shall use as its reference Standard UTC time/date (UTC +0).
4.2.3 Format
The time data shall have the following format: YYYYMMDDHHmmss:
a) YYYY : Year;
b) MM : Month;
c) DD: Day;
d) HH : Hour;
e) mm : Minute;
f) ss: Second.
4.2.4 Resolution level
The time data shall have resolution of 1 s.
4.2.5 Stability
-6
The internal time source shall have a stability of 20 x 10 or better.
4.2.6 Synchronisation
The internal time source shall not deviate from the reference time source by more than 2 s. This shall be
ensured by checking the synchronisation between the internal time source and one or more external time
source(s) on a regular basis.
All synchronisation events shall be logged.

SIST EN 50463-3:2013
EN 50463-3:2012 - 10 -
4.3 Energy data
4.3.1 Source
The DHS shall be able to receive energy data from one or more ECF.
If the DHS is capable of interfacing with multiple EMF in an EMS configuration, then the DHS shall be able to
identify each EMF uniquely. It shall be assured that the DHS allocates the energy data to the correct register
and CEBD.
4.3.2 Type
The DHS shall receive energy data from the ECF necessary for the creation of CEBD.
NOTE Each energy data will consist of two mandatory values (active energy consumed/regenerated) and two conditional values
(reactive energy consumed/generated).
4.3.3 Format
The values in the energy data received from an ECF will be in units of Watt-hour (active energy) and var-
hour (reactive energy) or their decimal-multiples.
The energy data received from an ECF is either energy delta values or energy index values or both.
If the only energy data received from an ECF are delta values and the DHS also produces optional index
vales, the DHS shall use these delta values to produce the index values.
If the only energy data received from an ECF are index values, the DHS shall use these index values to
produce the delta values.
If the energy data received from an ECF are index values and delta values, the DHS shall use these inputs
to produce energy data of the same type (e.g. delta inputs are used by the DHS to produce delta values
only).
NOTE The algorithms for producing energy delta values in CEBD are specified in 4.7.3.
4.3.4 Index value overrun
The DHS shall be able to detect any index value overrun in an ECF from the energy data received from the
ECF. When this occurs, the DHS shall still be able to calculate required energy delta values.
4.3.5 Merging with time data
Energy data in the DHS shall be accompanied by time data according to 4.2, where required for the
production of CEBD. If the energy data provided by the ECF does not include time data, the DHS shall add
time data without introducing any time displacement error to the energy data.
4.3.6 Energy data flags
The DHS shall accept any quality flags attached to the energy data received from the ECF.
The DHS shall ensure that all energy data in the DHS carries one the following types of quality flags:
a) Measured (code: 127): based on measurements and calculations in the ECF;
b) Uncertain (code: 61): indicating that the energy data transmitted from ECF may be wrong (e.g.
partially missing energy data, indications of EMF errors, flag “Uncertain” on energy data or time
data);
c) Non-existent (code: 46): no energy data available to DHS.
NOTE The codes are based on the ebIX-code system, UN/CEFACT Data Element 4405 Release D.05A.
4.3.7 k-factor
Any DHS intended to be able to receive energy data as secondary values from one or more ECF, shall be
able to:
---------------------- Page: 12 ----------------------
SIST EN 50463-3:2013
- 11 - EN 50463-3:2012
a) convert the secondary values to primary values upon reception of energy data to the DHS, by using
the correct k-factor;
b) store k-factor(s) in a non-volatile access-protected memory;
c) log each change of k-factor.
NOTE An ECF might be configured to send a flag to the DHS for each change of k-factor in the EMF. If not, the k-factor can also be
found in the essential information of the intended ECF.
4.3.8 Accuracy
Energy data production within the DHS shall not introduce errors which degrade the accuracy of the input
data.
4.3.9 Transmission from EMF
The DHS energy data transfer arrangements shall be compatible with its intended EMF(s). The transfer of
energy data from a compatible ECF shall enable the DHS to fulfil the requirements in 4.7.
The transfer arrangements shall ensure the DHS receives a complete set of energy data for each time
reference period before commencing the transfer of energy data for the next time period.
4.4 Location data
4.4.1 Source
The DHS shall be able to receive location data from an on board function providing location data originating
from an external source. It may also be able to receive location data from additional sources of location data
generated on board the traction unit.

52 Introduction
53 The energy Measurement System provides metering suitable for billing and may also be used for energy
54 management, e.g. energy saving.
55 The standard has been developed taking into account that in some applications the Energy Measurement
56 Function could be submitted to fiscal legal metrological certification.
57 This series of European Standards uses the functional approach to describe the Energy Measurement
58 System. These functions are implemented in one or more physical devices. The user of this series of
59 standards is free to choose the physical implementation arrangements.
60 Figure 1 illustrates the functional blocks of the EMS, their main sub-functions and the structure of the
61 dataflow, and is informative only. Only connections required by this series of standards are displayed. The
62 communication function has been omitted for clarity. Essential requirements for the Data Collection Service
63 on-ground are also covered by EN 50463-3.

70 1 Scope
71 This draft European Standard covers the requirements applicable to the Data Handling System of an Energy
72 Measurement System, to be used onboard railway traction units for the measurement of energy taken from
73 or returned to the Contact Line system.
74 The Data Handling System receives, produces and stores data, ready for transmission to any authorised
75 receiver of data on-board or on-ground. The main goal of the Data Handling System is to produce Compiled
76 Energy Billing Data and transfer it to an on-ground Data Collection Service. The Data Handling System can
77 support other functionality onboard or on-ground with data, as long as this does not conflict with the main
78 goal.
79 This document also includes the Essential Requirements for the Data Collection Service on-ground, relating
80 to the aquisition and storage of Compiled Energy Billing Data.
81 The Conformity Assessment arrangements for the DHS are specified in this document.

212 4.2.4 Resolution level
213 The time data shall have resolution of 1 s.
214 4.2.5 Stability
215 The internal time source shall have a stability of 20 ppm.
216 4.2.6 Synchronisation
217 The internal time source shall be checked for synchronisation with external time source on a regular basis to
218 ensure that the internal time source shall not deviate from the external time source (UTC+0) by more than 2
219 s.
220 4.2.7 Flags for time data
221 A quality flag shall be attached to the time data if a change (i.e. synchronisation, manual adjustment, error
222 etc) has resulted in a change of the DHS internal time source by 2 s or more.
223 This is necessary to highlight a change in time data (e.g. resulting in an abnormal TRP length which may
224 affect the subsequent processing and use of the associated data).
225 4.3 Energy data
226 4.3.1 Type
227 The DHS shall acquire from the EMF sets of energy data necessary for the creation of CEBD.
228 NOTE Each set of Energy Data will consist of two mandatory values (active energy consumtion/regeneration) and two conditional
229 values (reactive energy consumption/generation)
230 4.3.2 Format
231 The energy data received from EMF is either energy delta values or energy index values or both together.
232 In case that the data received from the EMF are only energy delta values and the DHS produce the optional
233 energy index values, DHS shall use the received delta values.
234 In case that the data received from the EMF are only energy index values, the DHS shall produce energy
235 delta values using the received index values.
236 In case that data received from the EMF are both energy delta values and energy index values, DHS shall
237 use respectively the received energy delta values and the received index values to produce the energy delta
238 values and energy index values of the CEBD.
239 NOTE The algorithms for producing energy delta values of CEBD are specified in 4.7.3.
240 4.3.3 Index value overrun
241 The DHS shall be able to detect any index value overrun in the ECF from the energy data received from the
242 ECF. When this occurs, the DHS shall still be able to calculate required energy delta values and energy
243 index values.
244 4.3.4 Merging with time data
245 Energy data in the DHS shall be accompanied by time data, where required for the production of CEBD. If
246 the energy data provided by the ECF does not include time data, the DHS shall add time data without
247 introducing any time displacement error to the energy data.
248 4.3.5 Energy data flags
249 The DHS shall accept any quality flags attached to the energy data received from the EMF.
250 The DHS shall, as a minimum, attach one the following types of quality flags to the energy data:
251 a) Measured (ebIX-code: 127): based on measurements and calculations in the EMF;
---------------------- Page: 11 ----------------------
oSIST prEN 50463-3:2011
prEN 50463-3:2011 - 10 -
252 b) Uncertain (ebIX-code: 61): indicating that the energy data transmitted from EMF may be wrong (e.g.
253 partially missing energy data, indications of EMF errors, flag “Uncertain” on energy data or time
254 data);
255 c) Non-existent (ebIX-code: 46): no energy data available to DHS.
256 Energy data produced in the DHS, shall adopt any quality flag attached to the energy data from which they
257 originate.
258 4.3.6 Energy K-factor
259 If the energy data received from the EMF is of secondary value, the DHS shall produce energy data of
260 primary value upon reception to the DHS, using the correct K-factor.
261 Any flag received from EMF indicating a change in K-factor for energy data, shall be logged in the DHS, and
262 shall result in quality flag “Uncertain” (see 4.3.5) being attached to the first following energy data.
263 4.3.7 Accuracy
264 Energy data produced by the DHS shall have the same accuracy level as the energy data from which they
265 originate.
266 4.3.8 Transmission from EMF
267 The DHS energy data transfer arrangements shall be compatible with its intended EMF. The transfer of
268 energy data from a compatible ECF shall enable the DHS to fulfil the requirements in 4.7.
269 NOTE The DHS must at the end of the TRP have received all consumption measured by the EMF for that period. This to avoid any
270 significant displacement of energy data between TRPs, in the sense that some energy data of one reference period is used as the basis
271 for the production of CEBD in the next TRP. This is independent of the number of transmissions per TRP.
272 4.4 Location data
273 4.4.1 Source
274 The DHS shall be connected to a location data source external to the traction unit that provides location data
275 about the geographical position of the EMS. Its application is mandatory except for traction units not crossing
276 tariff borders.The DHS may also have a location data source internal to the traction unit.
277 NOTE Tariff borders is defined as any geographical border between two pricing areas of difference in energy grid costs, energy prices,
278 CL losses, tax regimes or other cost-variables to be used with the energy data to produce a bill.
279
280 4.4.2 Format
281 Location data shall be based on the World Geodetic System, revision WGS 84.
282 Location data used in the DHS shall be expressed as Longitude and Latitude in one of the following formats:

284 4.4.3 Merging with time data
285 Any location data received by the DHS without time data, shall be compiled with the corresponding time data
286 by the DHS.
287 4.4.4 Accuracy
288 In open air the location data shall have an accuracy of at least 250 m.
289 4.4.5 Type
290 The Location data in the DHS shall have the following ranking order (a = highest rank):
291 a) Measured: location data based on coordinates provided from an source external to the traction unit,
292 giving longitude and latitude coordinates and these coordinates are not older than 15 s;
293 b) Estimated: location data based on coordinates provided by a calculation based on an onboard
294 system, and these coordinates are not older than 15 s;
295 c) Uncertain: location data older than 15 s.
296 If the DHS has available more than one source of location data, then location data with highest rank shall
297 always be used.
298 4.4.6 Location data flags
299 Location data shall be tagged with a quality flag based on its type:
300 a) Measured: 127 (ebIX-code);
301 b) Estimated: 56 (ebIX-code);
302 c) Uncertain: 61 (ebIX-code);
303 d) Non-existent: 46 (ebIX-code).
304 NOTE The codes are based on the ebIX-code system.
305 4.5 Other received or produced data
306 4.5.1 Types
307 The DHS may also handle and produce other data/datasets associated with other parts of the Energy
308 Measurement system, and provide support for operational surveillance and maintenance.
309 NOTE Examples of such data is Voltage level, Current Level and non-mandatory flags from the EMF.
310 4.5.2 Data handling prioritisation
311 Any data handling or communication linked to such data or activity shall not interfere with the flow and
312 processing of data associated with CEBD.
313 4.5.3 Time tag
314 Data covered by this chapter should have a time stamp in accordance with 4.2.3 or 4.2.4.

317 4.7 Production of CEBD
318 4.7.1 Type of Data
319 The DHS shall, at the end of each TRP, produce a set of Compiled Energy Billing Data (CEBD), by
320 assembling the following data:
321 a) time data;
322 b) energy delta values;
323 c) location data;
324 d) consumption point ID;
325 e) Quality flags;
326 f) energy index values (optional);
327 g) traction type flag (optional).
328 4.7.2 Time Reference Period
329 TRPs shall be consecutive 5 minute periods, originating from the time stamp 0000 (mmss, ref. 4.2.3).
330 The time data to be used in the CEBD shall be the end time of the TRP.
331 NOTE It is permitted to transmit energy data of shorter time period from on-board to on-ground, but this is not regarded as CEBD.
332 4.7.3 Energy data
333 The Energy delta values shall be complete sets of energy data according to sets of energy data received
334 from EMF.
335 NOTE 1 Each set of Energy Data received to the DHS will consist of two mandatory values (active energy consumtion/regeneration)
336 and two conditional values (reactive energy consumption/regeneration).
337 Energy delta values to be used in CEBD shall be produced for each TRP, by accumulating all energy delta
338 values with time data within the TRP or by calculating the difference between the energy index values at the
339 start and the end of the TRP.
340 The energy delta values to be used in CEBD shall be primary values including the first decimal place, with
341 any remainder being carried over and included within the next time reference period.
342 NOTE 2 The carry over ensures that no measured energy data is omitted overall, whilst permitting quantities less than 0,1 to be
343 deferred to a subsequent 5 minute time reference period.
344 If energy index values are used to produce the energy delta values in CEBD, and the energy index value for
345 the start of the TRP is missing, then the latest energy index value used previously in production of the latest
346 CEBD shall be used as a substitute. The energy delta values created under such conditions, shall be flagged
347 ‘Uncertain’ (see 4.3.5).
