_____________
Introduction to Amendment 1
This amendment is related to compatibility levels in the frequency range from 2 kHz to
150 kHz. It contains:
– compatibility levels for signals from mains communicating systems up to 150 kHz;
– compatibility levels for non-intentional emissions between 2 kHz and 30 kHz.
A second amendment is expected soon, containing:
– compatibility levels for non-intentional emissions between 30 kHz and 150 kHz.
1 Scope and object
Replace the existing text with the following new text:
This part of IEC 61000 is concerned with conducted electromagnetic phenomena
(disturbances and signals from mains communicating systems) in the frequency range from
0 kHz to 150 kHz. It gives compatibility levels for public low voltage a.c. distribution systems
having a nominal voltage up to 420 V, single-phase, or 690 V, three-phase, and a nominal
frequency of 50 Hz or 60 Hz.
The compatibility levels specified in this document apply at the point of common coupling. At
the power input terminals of equipment receiving its supply from the above systems, the
levels of the conducted electromagnetic disturbances can, for the most part, be taken to be
the same as the levels at the point of common coupling. In some situations this is not so,
particularly in the case of a long line dedicated to the supply of a particular installation, or in

© IEC 2017
the case of an electromagnetic phenomenon generated or amplified within the installation of
which the equipment forms a part.
Compatibility levels are specified for conducted electromagnetic phenomena of the types
which can be expected in public low voltage power supply systems, for guidance in the
definition of:
– the limits to be set for conducted emissions into public power supply systems (including
the planning levels defined in 3.1.5),
– the immunity limits to be set by product committees and others for the equipment exposed
to the conducted electromagnetic phenomena present in public power supply systems.
NOTE More information on compatibility levels and other main basic EMC concepts is given in IEC TR 61000-1-1.
The electromagnetic phenomena considered are:
– voltage fluctuations and flicker;
– harmonics up to and including order 40;
th
– interharmonics up to the 40 harmonic;
th
– voltage distortion in differential mode at higher frequencies (above the 40 harmonic up to
150 kHz);
– voltage dips and short supply interruptions;
– voltage unbalance;
– transient overvoltages;
– power frequency variation;
– d.c. components;
– signals from mains communicating systems (MCS).
Most of these phenomena are described in IEC TR 61000-2-1. In cases where it is not yet
possible to establish compatibility levels, some information is provided in Annex B.

Replace, in the explanation below the equation, value H, "…is generally equal to 50, but…"
with "…is generally equal to 40, but…".
4.3 Harmonics
In Table 1, replace:
17 ≤ h ≤ 49 with 17 ≤ h ≤ 37,
21 < h ≤ 45 with 21 < h ≤ 39,
10 ≤ h ≤ 50 with 10 ≤ h ≤ 40.
Add, after the existing subclause 4.4 the following new subclauses:
th
4.11 Voltage distortion in differential mode above the 40 harmonic up to 9 kHz
th
In this document, voltage distortion above the 40 harmonic up to 9 kHz is considered in
relation to long-term effects, i.e. for a duration of 10 min or longer.
th
In the case of voltage distortion at frequencies above the 40 harmonic, it is generally not
relevant whether they are at harmonic or interharmonic frequencies. They can occur both at
discrete frequencies and in relatively broad bands of frequencies.
th
The compatibility levels for voltage distortion in differential mode above the 40 harmonic
(exclusive) up to 9 kHz are given in Table 2. These compatibility levels are related to voltage
distortion levels between any two phase conductors or between any phase conductor and the
neutral conductor, in a bandwidth of 200 Hz, defined as follows:
100 /∆f
u = × U (F+n⋅∆f )

where
F (in Hz) is the centre frequency of the 200 Hz band under consideration (F is
between 2 100 Hz and 8 900 Hz for 50 Hz systems and between
2 500 Hz and 8 900 Hz for 60 Hz systems);
u is the voltage distortion level in the bandwidth of 200 Hz around centre
b,F
frequency F (expressed in percent of the fundamental component of the
voltage U );
U (in V) is the r.m.s. value of the fundamental component of the voltage;
U (F + n·Δf) (in V) is the r.m.s. value of the component of the voltage at frequency
f = F + n·Δf measured with the frequency resolution of Δf (in Hz).
NOTE 1 The 200 Hz bandwidth has been chosen such that it is in accordance with the bandwidth specified in
CISPR 16-1-1 for frequencies above 9 kHz.
