Interpretation of the second set of requirements applicable to Class C equipment with a
rated power ≥ 5 W and ≤ 25 W according to 7.4.3 of IEC 61000-3-2:2018 and
Introduction
The second set of requirements of 7.4.3 of IEC 61000-3-2:2018 and
that it reaches the 5 % current threshold before or at 60°, has its peak value before or at 65°
and does not fall below the 5 % current threshold before 90°, referenced to any zero crossing
of the fundamental supply voltage” and that “Components of current with frequencies above
9 kHz shall not influence this evaluation (a filter similar to the one described in 5.3 of
IEC 61000-4-7:2002 and IEC 61000-4-7:2002/AMD1:2008 may be used);”
Testing laboratories and Class C equipment manufacturers concluded that several harmonics
test systems with IEC 61000-4-7 compliant measurement equipment do not completely filter out
the components of current with frequencies above 9 kHz, thus resulting in a non-accurate
evaluation of the phase angles (see Figure 1). One of the reasons why filters are not used is
that they can alter the phase angle itself by introducing a phase delay.
Question
When applying the second set of requirements in 7.4.3, what method shall be used to measure
the phase angle in order to avoid the influence of components of current with frequencies above
9 kHz?
Interpretation
Given the issues reported by test laboratories, if the phase angle is measured with an
IEC 61000-4-7 test system that doesn’t remove the components above 9 kHz correctly, the
measurements with a digital oscilloscope shall prevail, where the components above 9 kHz
have been removed without affecting the phase angle at which the peak current occurs.
NOTE This can be achieved for example by using a synchronous averaging mode of the oscilloscope (see Figure 2).

Annex
Figure 1 and Figure 2 show an incorrect and the correct evaluation of the phase angle.
