  - Currently there are general limits for conducted emissions only in the frequency
    range up to 2 kHz [1],[2] and above 150 kHz [3]. Limits for the frequency range
    from 2 kHz to 9 kHz are in discussion. Because of this mentioned gap in the standards
    there is an uncertainty how to design filters and disturbance sources like converters.
    For finding limits investigations are necessary on mains impedances and harmonics.
    There are older publications on mains impedances (e. g. [4], [5]), but they include
    only measurements of impedances between one phase and neutral conductor and no
    measurements of impedances between the phases. This is important for three-phase
    loads. Furthermore in [4] no measurements were made in industrial mains and the
    investigations were carried out more than one decade ago. Especiaily in the last
    years the electrical environment in the mains has changed because of the increasing
    number of self-commutated converters. Accordingly, much higher amplitudes for
    harmonics in the upper frequency range are identifiable. In this paper current
    investigations on mains impedances and harmonics are presented which were carried
    out in universities, companies and private houses. The results could be used as
    a base for finding limits and for designing filters and disturbance sources economicaily.@eng
