National foreword
This British Standard is the English language version of EN 62053-61:1998. It
is identical with IEC 62053-61:1998.
The UK participation in its preparation was entrusted to Technical Committee
PEL/13, Electricity meters, which has the responsibility to:
— aid enquirers to understand the text;
— present to the responsible international/European committee any
enquiries on the interpretation, or proposals for change, and keep the UK
interests informed;

— monitor related international and European developments and
promulgate them in the UK.
A list of organizations represented on this committee can be obtained on
request to its secretary.
From 1 January 1997, all IEC publications have the number 60000 added to
the old number. For instance, IEC 27-1 has been renumbered as IEC 60027-1.
For a period of time during the change over from one numbering system to the
other, publications may contain identifiers from both systems.
Cross-references
Attention is drawn to the fact that CEN and CENELEC standards normally
include an annex which lists normative references to international
publications with their corresponding European publications. The British
Standards which implement these international or European publications may
be found in the BSI Standards Catalogue under the section entitled
“International Standards Correspondence Index”, or by using the “Find”
facility of the BSI Standards Electronic Catalogue.
A British Standard does not purport to include all the necessary provisions of
a contract. Users of British Standards are responsible for their correct
application.
Compliance with a British Standard does not of itself confer immunity
from legal obligations.

1 Scope

3 Definitions

This International Standard applies only to newly
manufactured “combined meters”, measuring more
than one type of electric energy (e.g. active and
reactive) and meters integrating additional

functions which are not in the scope of the
IEC 60687, IEC 61036, IEC 61268 standards and
the standard in preparation for static apparent
energy meters; these additional functions, all
related to electric energy metering are, for instance,
maximum demand indicator, time switches, ripple
control or radio receivers, etc.
When other devices and functions not related to
electric energy metering and billing are enclosed in
the same meter case (such as power line carrier
devices, load curve recording devices, telephone and
radio transceiver or network current and voltage
measurement and analysis devices, etc.) this
standard applies only to the energy metering and
processing section.
For all the meter characteristics and functions
already described in existing standards, these
standards will apply for the corresponding
characteristics and functions.

For the purpose of this International Standard, the
following definitions apply.

2 Normative references
The following normative documents contain
provisions which, through reference in this text,
constitute provisions of this part of IEC 62053. At
the time of publication, the editions indicated were
valid. All normative documents are subject to
revision, and parties to agreements based on this

part of IEC 62053 are encouraged to investigate the
possibility of applying the most recent editions of
the normative documents indicated below. Members
of IEC and ISO maintain registers of currently valid
International Standards.

has functions that are not described in the basic
standards for watt-hour, var-hour and VA-hour
meters
NOTE Multi-function meters may include: maximum demand
indicator, time switches, ripple control or radio receivers, pulse
output devices, etc.

a

For polyphase meters the burden is supposed to be evenly shared between the two or three phases supplied. Should a phase
voltage be missing it is admitted that the maximum consumption per phase is higher than specified. However the meter shall
continue to operate correctly.
b The total power required for meters with these additional functions can be agreed upon between the user and the manufacturer.

In order to match voltage transformers to meters
the manufacturer shall state if the burden is
inductive or capacitive.
The figures in Table 1 are mean values. Switching
power supplies with peak power values in excess of
these specified values are permitted, but it should
be ensured that the rating of associated voltage
transformers is adequate.
If the meter is operated with an auxiliary power
supply, Table 1 is not applicable and the maximum
consumption of this power supply can be agreed
upon between the user and the manufacturer. The
consumption of each voltage circuit shall be less

than 2 W and 10 VA.

5 Tests and test conditions

4.3.2 Current circuits

5.2 Test of power consumption

For multi-energy meters the consumption shall be
not greater than the values specified in the
appropriate standards.

The power consumption in the voltage and current
circuit shall be determined at reference values of the
influence quantities given in IEC 61036. The overall
precision shall be better than 5 %.

4.4 Voltage range

NOTE The polyphase meters should also operate within
these ranges for one phase only.

5.1 General testing procedures
5.1.1 Test conditions
All tests shall be carried out under reference
conditions according to IEC 61036.
NOTE To simplify the tests, the test conditions will be
according to IEC 61036.

5.1.2 Type test
The type test defined in IEC 61036 shall be made on
one or more specimens of the meter selected by the
manufacturer, to establish its specific
characteristics and to prove its conformity with the
requirements of this standard.

5.2.1 Test of power consumption of voltage
circuits
For requirements, see 4.3.1.
5.2.2 Test of power consumption of current
circuits
For requirements, see 4.3.2.
