1 Scope and object
Renumber the existing note, as modified by Amendment 1, into NOTE 1.
After the existing note, add the following new note:
NOTE 2 The measurement methods of disturbance levels are outside the scope of this document.

4.2 Voltage fluctuations and flicker
Add, after Figure 1, the following new text:
In some cases, it is necessary to use the numerical values for points on the curves in
Figure 1. These values are given in Table E.1.

4.12.3 Frequency range from 30 kHz to 150 kHz
Replace the existing text, as modified by Amendment 1, with the following new text and Table:
The compatibility levels for voltage distortion in differential mode from 30 kHz to 150 kHz are
given in Table 4.

For EMC coordination in the setting of emission limits for unsymmetrical voltage
distortion, see 4.12.1.
b
At the transition frequency, the lower level applies.
c
The level decreases linearly with the logarithm of the frequency in the ranges
30 kHz to 50 kHz and 50 kHz to 150 kHz.

Annex D has been prepared in order to provide the basis for the definition of compatibility
levels in the frequency range from 30 kHz to 150 kHz.
Add the following new Annexes D and E:

Annex D
(informative)
Basis for the definition of the compatibility levels for voltage
distortion in differential mode from 30 kHz to 150 kHz
D.1 General
A number of electromagnetic interference cases due to disturbances in the frequency range
from 2 kHz to 150 kHz have been collected by IEC and CENELEC. Consequently, it was
decided to start the maintenance of IEC 61000-2-2 mainly to define compatibility levels in this
frequency range, from which associated emission limits and immunity requirements can be
derived.
D.2 Compatibility levels
The compatibility levels for voltage distortion in differential mode from 30 kHz to 150 kHz are
reference levels for coordination in the setting of emission limits and immunity levels, in order
to improve EMC (including long-term degradation) for equipment such as MCSs, static
electricity meters, clocks, filter capacitors, etc, supplied by public low voltage power supply
systems, against disturbances generated by equipment such as switching power converters,
switch mode power supplies, photovoltaic inverters, etc. Several additional parameters other
than the disturbance level can have an impact on EMC in this frequency range, such as
impedance behaviour of the mains and attenuation effects, global voltage spectrum and time
behaviour of conducted emissions, as well as the expected amount of equipment supplied by
public low voltage power supply systems (see the note in 4.12.1).
In particular, MCSs cannot work properly when the levels of disturbance are too high. Today,
in 2017, emission limits for the frequency range from 30 kHz to 150 kHz are defined only for a
few types of equipment. When defining emission limits in this range, CISPR 15 limits should
be considered, when possible. Their use would allow a better design of the MCS network
leading to a better operation; in the majority of cases, harmful interferences could be better
managed and solved at reasonable cost. Additionally, tests have shown that the performance
of multicarrier MCSs depends not only on the amplitude but also on the shape and the
number of spectral lines of disturbances: a few lines are expected to be less harmful than a
large number.
In other respects, the definition of a very low compatibility level curve for non-intentional
emissions is not reasonable due to the estimated high cost for making all equipment
compliant with emission limits consistent with this compatibility level curve.
The proposed compatibility level curve is the result of the efforts made by the different parties
to reach a compromise, after years of intense discussions and studies within IEC SC77A, also
taking into account investigation results from CENELEC SC205A. This compatibility level
curve represents the best currently achievable compromise supported by all stakeholders,
giving for the first time a reference level for setting emission limits for non-intentional
emissions in the frequency range from 30 kHz to 150 kHz.

NOTE 1 Two consecutive voltage changes (one positive and one negative) constitute one “cycle”, i.e. two voltage
changes per second correspond to a 1 Hz fluctuation.
NOTE 2 The lines with 3 digits behind the decimal comma are used in Table 5 of IEC 61000-4-15 where they are
specified for calibration purposes, and are therefore given with higher resolution.
NOTE 3 The lines for 4 000 changes per minute and 4 800 changes per minute on the above table, which are not
in Figure 1, are given only because they are used in Table 5 of IEC 61000-4-15.
