Electromagnetic compatibility (EMC) -- Part 4-13: Testing and measurement techniques - Harmonics and interharmonics including mains signalling at a.c. power port, low frequency immunity tests
This part of IEC 61000 defines the immunity test methods and range of recommended basic
test levels for electrical and electronic equipment with rated current up to 16 A per phase at
disturbance frequencies up to and including 2 kHz (for 50 Hz mains) and 2,4 kHz (for 60 Hz
mains) for harmonics and interharmonics on low voltage power networks.
It does not apply to electrical and electronic equipment connected to 16 2/3 Hz , or to 400 Hz
a.c. networks. Tests for these networks will be covered by future standards.
The object of this standard is to establish a common reference for evaluating the functional
immunity of electrical and electronic equipment when subjected to harmonics and interharmonics
and mains signalling frequencies. The test method documented in this part of IEC
61000 describes a consistent method to assess the immunity of an equipment or system
against a defined phenomenon. As described in IEC guide 107, this is a basic EMC publication
for use by product committees of the IEC. As also stated in Guide 107, the IEC product
committees are responsible for determining whether this immunity test standard should be
applied or not, and if applied, they are responsible for determining the appropriate test levels
and performance criteria. TC 77 and its sub-committees are prepared to co-operate with
product committees in the evaluation of the value of particular immunity tests for their products.
The verification of the reliability of electrical components (for example capacitors, filters, etc.)
is not in the scope of the present standard. Long term thermal effects (greater than 15 min) are
not considered in this standard.
The levels proposed are more adapted for residential, commercial and light industry
environments. For heavy industrial environments the product committees are responsible for
the definition of a class X with the necessary levels. They have also the possibility of defining
more complex waveforms for their own need. Nevertheless, the simple waveforms proposed
have been mainly observed on several networks (flat curve more often for single phase
system) and also on industrial networks (overswing curve more for three phase systems).

Electromagnetic compatibility (EMC) - Part 4-13: Testing and measurement techniques - Harmonics and interharmonics including mains signalling at a.c. power port, low frequency immunity tests (IEC 61000-4-13:2002)
Ta del standarda IEC 61000 določa metode za preskus odpornosti in obseg priporočenih osnovnih preskusnih ravni za električno in elektronsko opremo z nazivnim tokom največ 16 A na fazo pri motečih frekvencah največ 2 kHz (za omrežja s frekvenco 50 Hz) ter 2,4 kHz (za omrežja s frekvenco 60 Hz) za harmonike in medharmonike v nizkonapetostnih električnih omrežjih. Ne uporablja se za električno in elektronsko opremo, povezano z omrežjem 16 2/3 Hz ali 400 Hz (izmenični tok). Preskusi za ta omrežja bodo zajeti v prihodnjih standardih. Namen tega standarda je določiti skupno referenco za ocenjevanje funkcionalne odpornosti električne in elektronske opreme pri izpostavljenosti harmonikom in medharmonikom ter frekvencam napetostnih signalov v omrežju. Preskusna metoda, dokumentirana v tem delu standarda IEC 61000, opisuje skladno metodo za oceno odpornosti opreme ali sistema proti opredeljenemu pojavu. To je osnovna objava o elektromagnetni združljivosti, ki jo uporabljajo tehnični odbori v okviru Mednarodne elektrotehniške komisije (IEC), kot je opisano v vodilu 107 Mednarodne elektrotehniške komisije. Poleg tega je v vodilu 107 navedeno, da so tehnični odbori v okviru Mednarodne elektrotehniške komisije odgovorni za določitev morebitne uporabe tega standarda s preskusom odpornosti, v primeru uporabe pa so odgovorni za določitev ustreznih preskusnih ravni in meril učinkovitosti. Odbor TC 77 in njegovi pododbori so pripravljeni za sodelovanje s tehničnimi odbori pri vrednotenju posameznih preskusov odpornosti za ustrezne izdelke. Preverjanje zanesljivosti električnih komponent (npr. kondenzatorjev, filtrov itd.) je zunaj področja uporabe trenutnega standarda. Ta standard ne obravnava dolgoročnih toplotnih učinkov (več kot 15 min).
Predlagane ravni so bolj prilagojene za stanovanjska, poslovna in manj zahtevna industrijska okolja. Za zahtevna industrijska okolja so tehnični odbori odgovorni za določitev razreda X s potrebnimi ravnmi. Za svoje potrebe lahko določijo tudi bolj zapletene valovne oblike. Vendar v številnih omrežjih (ravna krivulja pogosteje za enofazni sistem) in tudi industrijskih omrežjih (zaobljena krivulja pogosteje za trifazne sisteme) je bilo mogoče opaziti v glavnem predlagane preproste valovne oblike.

FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, the IEC publishes International Standards. Their preparation is
entrusted to technical committees; any IEC National Committee interested in the subject dealt with may
participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. The IEC collaborates closely with the International Organization
for Standardization (ISO) in accordance with conditions determined by agreement between the two
organizations.
2) The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, an
international consensus of opinion on the relevant subjects since each technical committee has representation
from all interested National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical specifications, technical reports or guides and they are accepted by the National
Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 61000-4-13 has been prepared by subcommittee 77A: Low
frequency phenomena, of IEC technical committee 77: Electromagnetic compatibility.
This standard has the status of a basic EMC publication in accordance with lEC Guide 107.
The text of this standard is based on the following documents:
FDIS Report on voting
77A/368/FDIS 77A/377/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 3.
Annexes A, B, and C, are for information only.

ELECTROMAGNETIC COMPATIBILITY (EMC) –
Part 4-13: Testing and measurement techniques –
Harmonics and interharmonics including mains signalling at
a.c. power port, low frequency immunity tests
1 Scope and object
This part of IEC 61000 defines the immunity test methods and range of recommended basic
test levels for electrical and electronic equipment with rated current up to 16 A per phase at
disturbance frequencies up to and including 2 kHz (for 50 Hz mains) and 2,4 kHz (for 60 Hz
mains) for harmonics and interharmonics on low voltage power networks.
It does not apply to electrical and electronic equipment connected to 16 2/3 Hz , or to 400 Hz
a.c. networks. Tests for these networks will be covered by future standards.
The object of this standard is to establish a common reference for evaluating the functional
immunity of electrical and electronic equipment when subjected to harmonics and inter-
harmonics and mains signalling frequencies. The test method documented in this part of IEC
61000 describes a consistent method to assess the immunity of an equipment or system
against a defined phenomenon. As described in IEC guide 107, this is a basic EMC publication
for use by product committees of the IEC. As also stated in Guide 107, the IEC product
committees are responsible for determining whether this immunity test standard should be
applied or not, and if applied, they are responsible for determining the appropriate test levels
and performance criteria. TC 77 and its sub-committees are prepared to co-operate with
product committees in the evaluation of the value of particular immunity tests for their products.
The verification of the reliability of electrical components (for example capacitors, filters, etc.)
is not in the scope of the present standard. Long term thermal effects (greater than 15 min) are
not considered in this standard.
The levels proposed are more adapted for residential, commercial and light industry
environments. For heavy industrial environments the product committees are responsible for
the definition of a class X with the necessary levels. They have also the possibility of defining
more complex waveforms for their own need. Nevertheless, the simple waveforms proposed
have been mainly observed on several networks (flat curve more often for single phase
system) and also on industrial networks (overswing curve more for three phase systems).

4 General
4.1 Description of the phenomenon
4.1.1 Harmonics
Harmonics are sinusoidal voltages and currents with frequencies that are integer multiples of
the frequency at which the supply system operates.
Harmonic disturbances are generally caused by equipment with non-linear voltage – current
characteristics or by periodic and line-synchronised switching of loads. Such equipment may be
regarded as sources of harmonic currents.
The harmonic currents from the different sources produce harmonic voltage drops across the
impedance of the network.
As a result of cable capacitance, line inductance and the connection of power factor correction
capacitors, parallel or series resonance may occur in the network and cause a harmonic
voltage amplification even at a remote point from the distorting load. The waveforms proposed
are the result of the summation of different harmonic orders of one or several harmonic
sources.
4.1.2 Interharmonics
Between the harmonics of the power frequency voltage and current, further frequencies can be
observed which are not an integer multiple of the fundamental. They can appear as discrete
frequencies or as a wide-band spectrum. Summation of different interharmonic sources is not
likely and is not taken into account in this standard.
4.1.3 Mains signalling (ripple control)
Signal frequencies ranging from 110 Hz to 3 kHz used in networks or parts of them in order to
transfer information from a sending point to one or more receiving points.
For the scope of this standard, the frequency range is limited to 2 kHz/50 Hz (2,4 kHz/60 Hz).
4.2 Sources
4.2.1 Harmonics
Harmonic currents are generated to a small extent by generation, transmission and distribution
equipment and to a greater extent by industrial and residential loads. Sometimes, there are
only a few sources generating significant harmonic currents in a network; the individual
harmonic level of the majority of the other devices is low, nevertheless these may make a
relatively high contribution to the harmonic voltage distortion, at least for low order harmonics
due to their summation.
Significant harmonic currents in a network can be generated by non-linear loads, for example:
---------------------- Page: 12 ----------------------
61000-4-13 © IEC:2002 – 17 –
– controlled and uncontrolled rectifiers, especially with capacitive smoothing (for example
used in television, indirect and direct static frequency converters, and self-ballasted lamps),
because these harmonics are in approximately the same phase from different sources and
there is only poor compensation in the network;
– phase controlled equipment, some types of computers and UPS equipment.
Sources may produce harmonics at a constant or varying level, depending on the method of
operation.
4.2.2 Interharmonics
Sources of interharmonics can be found in low-voltage networks as well as in medium-voltage
and high voltage networks. The interharmonics produced in the medium-voltage/high voltage
networks flow in the low-voltage networks they supply and vice versa.
The main sources are indirect and direct static frequency converters, welding machines and
arc furnaces.
4.2.3 Mains signalling (ripple control)
Sources of mains signalling frequencies covered by this standard are transmitters operating
mostly in the 110 Hz to 2 kHz (2,4 kHz) frequency range in order for the public supplier to
control equipment in the supply network (public lighting, tariffs for meters, etc.). The transmitter
energy is coupled into the system on HV, MV, or LV level. The transmitters operate with
interrupted signals, and normally for a short time only. The frequencies used lie normally in
between the harmonics.
5 Test levels
The test level is the harmonic voltage specified as a percentage of the fundamental voltage.
The voltages given in this standard have the nominal power supply network voltage (U
1
fundamental) as a basis.
It is essential that the r.m.s. voltage of the resultant waveforms remain at the nominal value
during the application of these tests by adjusting the voltage values of fundamental and
harmonics according to the percentages indicated in the corresponding tables (for example
230 V r.m.s., 120 V r.m.s.).
5.1 Harmonics test levels
The preferential range of test levels for individual harmonics are given in tables 1 to 3.
Harmonic voltages at a test level of 3 % and higher, up to the 9th harmonic, shall be applied
using a phase shift of both 0° and 180° with respect to the positive zero-crossing of the
fundamental. Harmonic voltages at a test level of less than 3 % shall be applied using no
phase-shift with respect to the positive zero-crossing of the fundamental.
For compatibility levels see IEC 61000-2-2 using factor k. Immunity levels have to be higher
(for example times 1,5 additionally).
The application of the test to a multiphase EUT is given in 8.2.5.

Immunity test levels for interharmonics above 100 Hz are covered by the mains signalling
levels and optionally by the Meister curve levels defined in 8.2.4. Mains signalling levels are in
the range of 2 % to 6 % of U Discrete interharmonic frequencies have a level of about 0,5 %
1.
of the fundamental frequency voltage U (in absence of resonance). In class 3 for industrial
1
networks, these levels can be considerably higher.
6 Test instrumentation
6.1 Test generator
The test generator shall have the ability to generate a signal with a 50 Hz or 60 Hz fundamental
frequency and to superimpose the required frequencies (harmonics and frequencies between
the harmonics).
The test generator shall have sufficient filtering such that the harmonic and interharmonic
disturbances do not influence any auxiliary equipment which may be used to perform the test.
The test levels according to tables 1 to 4 shall be applied at the terminals of the EUT
connected as in normal conditions (single or three phase) and operating as specified in the
relevant product standard.
The test generator shall have the following specifications:
