Introduction
This European Standard has been prepared using EN 62053 as reference standard. As many
new requirements and tests had to be added, this new standard has been split into five clauses,
namely
1 Scope
2 Normative references
3 Definitions
4 Requirements
5 Tests and test conditions.
For all tests which are not specified in this standard, the existing IEC publications apply.
This standard covers the "standard meter", which may be used for energy metering on board
trains. It does not deal with special features (such as solution with the section that perform the
measure in separate housing respect to display). These might be covered in separate
International Standards.
This standard considers accuracy class 1.
The test levels are regarded as minimum values to ensure the proper functioning of the meter
under normal working conditions. For special application, alternative test levels might be
necessary and should be agreed by the user and the manufacturer.
A static meter faces the same general environmental conditions as the other electronic devices
on board trains. Therefore, the specification will implement all the requirements set by EN 50155
for class TX.
Regarding the influence of harmonics, special test procedures had to be incorporated. These
tests check the functionality of the meter when the meter is exposed to large distortions in the
current circuit and the accuracy of the meter with 5th harmonic in the current and voltage circuit
(see Annex B).
To test accurate operation of the meter under practical conditions have been specified
(see 5.7.2.2):
half-wave rectification (d.c. and even harmonics);
•
• phase-fired control (odd harmonics);
• burst control (sub-harmonics).
To check if a meter accurately measures total energy in the presence of harmonics, a test with
5th harmonic in both the current and voltage circuits has been specified. It is assumed that
correct measurement of 5th harmonic energy indicates that measurement for other harmonics will
be good.
The reliability aspects of equipment for electrical energy measurement and load control will be
handled separately.
For tests and test conditions, existing tests and test levels have been taken from EN 62053 and
IEC or EN standards as appropriate.
The IEC and EN publications referred to in this standard are listed in Clause 2.
