Following to [1, 2, 3] having proceeded with the collection of related information, with this Technical Report, further extended information is provided including:

the given EMC problems in the frequency range 2 kHz – 150 kHz, concerning EMC between electrical equipment in general as well as EMC between non-mains communicating equipment / systems (NCE) and mains communicating systems (MCS) as a particular issue
the given situation of related emissions in the grid, with other measurement results
EMI cases and related investigation results
new findings on parameters to be considered when dealing with EMC in this frequency range, in particular related to
the impact of the network impedance and its variation over time on the more or less disturbing effect of emissions in this frequency range
the behaviour of emissions in this frequency range over time and the increasing need for performing also time domain measurements for comprehensively evaluating emissions and their disturbance potential
the actual standardisation situation
needs for the future, concerning
measurement of related emissions
investigation on the impedance of the grid / in installations over time
closing gaps in standardisation
installation guidelines and possibly regulatory measures related to the ageing effect.

In light of different positions on and in evaluating related EMC problems, with additional measurement results concerning emission levels in the supply network and results from investigations of additional proven EMI cases, the given problems are highlighted in more detail and recommendations for what to do in the future are provided.
