Authorisation granted for 14 measurement transformer models

The Bizkaia Territorial Delegation authorises the installation of 14 models of current and voltage measurement transformers manufactured by Electrotécnica Arteche Hermanos, SL, based on Royal Decree 1110/2007 and UNE-EN 61869 standards. Transformer families include AC, AE, IF, IC and UC/UX. The installation period is not specified, but technical and safety conditions are imposed (arts. 2, 3).

In 3 key points

  1. Authorisation for 14 models of current and voltage measurement transformers (art. 2)
  2. Compliance with Royal Decree 1110/2007 and UNE-EN 61869 standards (art. 3)
  3. Installation period not specified; only technical compliance required (art. 3)

How it affects those involved

For companies installing measurement equipment on electrical networks, this provides a legal pathway to use these transformers without new authorisations, provided compliance with current regulations is maintained (art. 3). Companies must verify that the transformers have not undergone modifications affecting their functionality since their last certification (September 1, 2021 resolutions). Non-compliance with UNE-EN 61869-1, -2, -3 standards may result in administrative sanctions.
