Rekommandation 7: Tekniske bestemmelser m.v. for 10-15-20 kV nulpunktstransformere / Recommendation 7: Technical terms and conditions etc. for 10-15-20 kV earthing transformers
English version available. Bestemmelserne omfatter 10-20 kV nulpunktstransformere for opstilling i 50-60 kV stationer. Nulpunktstransformeren fungerer her både som egenforsyningstransformer og som tilkoblingsled for 10-20 kV slukkespoler.
I bestemmelserne specificeres den tekniske udførelse af disse 10-20 kV olieisolerede nulpunktstransformere samt det tilbehør som normalt indgår i leverancen.
Betegnelsen olie dækker i denne forbindelse også syntetisk isolerolie (askarel o.l.).

Recommendation 7: Technical terms and conditions etc. for 10-15-20 kV earthing transformers
This recommendation applies to three-phase, oil-immersed earthing transformers for the supply of solidly earthed, low voltage power in primary substations in 10-15-20 kV networks. The primary side neutral point constitutes the point of connection for 10-15-20 kV arc-suppression-coils, see DEFU Recommendation 3.
The recommendation is published in Danish and English. In case of discrepancy between the two versions the Danish version shall prevail.
