AS 62053.61:2018 pdf download.Electricity metering equipment (a.c.)——Particular requirements Part 61: Power consumption and voltage requirements (IEC 62053-61:1998, MOD).
1 Scope
This International Standard applies only to newly manufactured “combined meters”, measuring more than one type of electric energy (e.g. active and r eactive) and m eters integrating additional functions which are not in the scope of the IEC 60687, IEC 61036, IEC 61268
standards and the s tandard 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 f unctions not r elated to elec tric energy metering and billing ar e 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 m easurement and analysis devices, etc.) this standard applies only to the ener gy 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.
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.
IEC 60687:1992, Alternating current static watt-hour meters for active energy (classes 0,2 S and 0,5 S)
IEC 61036:1996, Alternating current static watt-hour meters for active energy (classes 1 and 2) IEC 61268:1995, Alternating current static var-hour meters for reactive energy (classes 2 and 3)
3 Definitions
For the purpose of this International Standard, the following definitions apply.
3.1 multi-energy meter
meter which, in a s ingle case, measures two or three types of energies (watt-hour, var-hour, VA-hour)
3.2 multi-function meter
basic or multi-energy meter which, in a single case, has functions that are not described in the basic standards for watt-hour, var-hour and VA-hour meters
NOTE — M ulti-function meters may include: maximum demand indicator, time switches, ripple control or radio receivers, pulse output devices. etc.
4 Requirements
4.1 Standard electrical values Refer to IEC 61036.
4.2 Name-plates
Refer to IEC 61036, with the following additions:
b) designation of type (see definition 3.1.4 in IEC 61036) ; each type of measurement performed (watt-hour, var-hour and VA-hour) shall be indicated:
I) the class index of each type of measurement (watt-hour, var-hour and VA-hour).
4.3 Power consumption
4.3.1 Voltage circuits
The active and apparent power consumption in eac h voltage c ircuit of a m eter at reference voltage, reference temperature and reference frequency (see 5.1.1) shall not ex ceed the values shown in table 1.In order to match voltage transformers to meters the m anufacturer shall state if the burden is inductive or capacitive.
The figures in table 1 ar e mean values. Switching power supplies with peak power values in excess of these specified values are permitted, but it s hould be ens ured that the r ating of associated voltage transformers Is adequate.
If the meter is operated with an auxiliary power supply, table 1 is not applic able and the maximum consumption of this power supply can be agr eed upon betw een the us er and the manufacturer. The consumption of each voltage circuit shall be less than 2 W and 10 VA.
4.3.2 Current circuits
For multi-energy meters the consumption shall be not greater than the values specified in the appropriate standards.
5 Tests and test conditions
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 es tablish its specific characteristics and to pr ove its conformity with the requirements of this standard.
5.2 Test of power consumption
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%.
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.AS 62053.61 pdf download.
