Division 1.4 For the one-to-one replacement of existing medium power pole-mounted transformers with power ratings between 25 kVA and 400 kVA, the applicable maximum levels of load and no-load losses are not the ones in Tables I.1 and I.2, but those in Table I.6 below. Maximum allowable losses for kVA ratings other than those explicitly mentioned in Table I.6 shall be obtained by linear interpolation or extrapolation. The correction factors for special combinations of winding voltages indicated in Tables I.3a and I.3b are also applicable.F1

For the one-to-one replacement of existing medium power pole-mounted transformers, the manufacturer, importer or authorised representative shall include in the technical documentation of the transformer the following information:

• the address and contact details of the commissioner of the replacement transformer;

• the station where the replacement transformer is to be installed. This shall be unequivocally identified either by a specific location or an specific installation type (e.g. technical description of the pole).

In the above cases, the manufacturer, importer or authorised representative shall notify the competent national market surveillance authorities.

With regard to the installation of new pole-mounted transformers, it is the requirements in Tables I.1 and I.2, in conjunction with Tables I.3a and I.3b where justified, which are applicable.
