ZES ZIMMER provides the system CE-Test61k for compli-
ance tests corresponding to standards EN 61000-3-2, -3,
-11 and -12. The precision power analyzers
LMG95 and
LMG500 comply with the standards for measurement
devices EN 61000-4-7 for harmonic analyzers and standard
EN 61000-4-15 for flicker meters. For validating the con-
firmation to the standards for current harmonics, the device
under test must be fed by a power source with a purely
sinusoidal and stable output voltage. This is essential in
order to proof that the measured current harmonics are
generated by the device under test and do not originate
from the source. Therefore the
ZES ZIMMER LMG devices
test the voltage stability and that distortions by harmonics
are within permissible limits during each analysis interval.
In addition to a power source, the flicker test requires a
well-defined reference impedance. Flicker is determined
by the amplitude and occurrences of line voltage fluctua-
tions. Voltage fluctuations are the result of current varia-
tions induced by the consuming device at the reference
impedance. In order to obtain results which can be com-
pared with others, a normalized line impedance must be
inserted between the feeding source and the test sample
when measuring flicker. The impedance values for these
reference impedances are defined as (0.24+j0.15)
Ω in the
phases and (0.16+j0.10)
Ω in the neutral. The test soft-
ware allows to record all device settings and measured
data and to process them into a test protocol that is man-
datory for the CE declaration.
