Description
The OLTC gives a regulation range of up to 22 % and up to 27 steps. For the off-circuit tap changer a typical range is, for example, ±5 %. Vector groups are YNd5, YNd11, YNyn0 and YNyn6, with and without a compensation winding. The transformers comply with IEC 60076, VDE 0532 and IEC 60354. Production is in Germany, Malaysia and the USA.
