7.3 General Aspects of Harmonics Emission
An adjustable frequency drive takes up a non-sinusoidal
current from the line power, which increases the input
current I
RMS
. A non-sinusoidal current is transformed by
means of a Fourier analysis and split up into sine-wave
currents with different frequencies, i.e. different harmonic
currents I
N
with 50 Hz as the basic frequency:

Table 7.5
The harmonics do not affect the power consumption
directly but increase the heat losses in the installation
(transformer, cables). Consequently, in plants with a high
percentage of rectifier load, maintain harmonic currents at
a low level to prevent an overload of the transformer and
high temperature in the cables.
