"The laboratories that are STL members carry out the testing and certification of electrical equipment, ensuring that they comply with IEC or equivalent standards"

TECNALIA attended the 71st STL Technical Committee Meeting at which documents related to IEC standards in the electricity sector are drawn up

TECNALIA attended the 71st STL (Short-circuit Testing Liaison) Meeting held in Lyon, France. This meeting consists of an association of the world's leading power laboratories, at which documents are drawn up for the harmonised interpretation of the IEC standards related to the electrical sector. Members of this organisation may issue STL certificates for electrical equipment within the scope of the group.

Members of this association should be actively involved in the preparation of Guides to the standards. It was under this premise that TECNALIA participated in the annual meeting organised by CERDA Labs, currently owned by General Electric.

Over the course of the meeting, the different participants presented papers on technical aspects of the standards, which were discussed intensively by the other members.

Agustín Ramos, as the representative of TECNALIA and the AELP (Spanish Association of Power Laboratories), presented a technical paper on internal arc tests in a transformer substation, which aims to protect the safety of people in the event of an electrical fault.
