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.

Untersuchungsergebnisse zu elektromagnetischen Interferenzen im Frequenzbereich unter 150 kHz

Résultats des études réalisées sur le brouillage électromagnétique dans la plage des fréquences inférieures à 150 kHz

Rezultati študije elektromagnetnih interferenc v frekvenčnem območju pod 150 kHz

V skladu s točkami [1, 2, 3] in na podlagi nadaljnjega zbiranja povezanih informacij so v tem tehničnem poročilu podane naslednje podrobne informacije, ki vključujejo:
– težave z elektromagnetno združljivostjo v frekvenčnem območju od 2 kHz do 150 kHz, ki se nanašajo na elektromagnetno združljivost med električno opremo na splošno ter elektromagnetno združljivost med neomrežno komunikacijsko opremo/sistemi (NCE) in omrežnimi komunikacijskimi sistemi (MCS) kot posebno težavo;
– stanje povezanih emisij v omrežju v danem trenutku, z drugimi rezultati meritev;
– primere elektromagnetnih motenj in povezani rezultati preiskave;
– nove ugotovitve o parametrih, ki jih je treba upoštevati pri obravnavanju elektromagnetne združljivosti v tem frekvenčnem območju, zlasti glede:
a) vpliva omrežne impedance in njene spremembe v časovnem obdobju na bolj ali manj moten učinek emisij v tem frekvenčnem območju,
b) obnašanja emisij v tem frekvenčnem območju v določenem časovnem obdobju in naraščajoče potrebe po opravljanju tudi meritev časovne domene za celovito oceno emisij in njihovih možnosti za povzročanje motenj;
– dejansko stanje standardizacije;
– nadaljnje potrebe glede:
a) meritve povezanih emisij,
b) preverjanja impedance v omrežju/napravah v določenem časovnem obdobju,
c) zapiranja vrzeli pri standardizaciji,
d) smernic za vgradnjo in morebitnih regulativnih ukrepov v zvezi z učinkom staranja.
Glede na različne položaje pri ocenjevanju povezanih težav elektromagnetne združljivosti z dodatnimi rezultati meritev ravni emisij v omrežju oskrbe in rezultati preiskav dodatnih dokazanih primerov elektromagnetnih motenj so omenjene težave podrobneje obravnavane in podana so priporočila glede nadaljnjih ustreznih ukrepov.
