INTAS presentations from Fifth international workshop on Power Transformer Performances online
Four INTAS presentations from the Fifth international workshop on Power Transformer Performances available online for download.
The INTAS project has started in March 2016 and will end in February 2019. It supposed to address the need to support European Market Surveillances Authorities (MSAs) deliver compliance with Ecodesign requirements for large industrial products, specifically transformers and fans. By acknowledging the current lack of expertise, experience, and resources available across Europe for this type of testing, INTAS will provide technical and cooperative support, as well as capacity building activities, to MSAs in charge of enforcing Ecodesign regulations. It will also support industry to be sure of what their obligations are under the Ecodesign Directive and to deliver compliance in a manner that will be broadly accepted by MSAs. By doing so, INTAS will foster a common European approach to the delivery and verification of compliance for these products. The aim of the INTAS project is to provide technical and cooperative support, as well as capacity building activities, to Market Surveillance Authorities (MSAs). The need for the INTAS project arises from the difficulty that MSAs and market actors face in establishing and verifying compliance with energy performance requirements for large industrial products subject to requirements of the Ecodesign Directive, specifically transformers and industrial fans. Today we will focus on transformers.
This presentation will present the main reactions of the partners in the national focal point meetings to the proposed market surveillance procedures developed by the INTAS project.
The INTAS project has been specifically designed around stakeholder engagement, providing national and European platforms for relevant target groups. National partners acting as National Focal Points (NFPs) target 10 EU Member States and engage with a wide set ofnational stakeholders such as manufacturers, users of the products, NGOs, relevant government departments and ministries, universities, and research institutions. This system allows not only for dissemination of information, but also an open communication channel throughout the project’s duration, and helps to guide and improve the work undertaken within INTAS. ECOS will present the procedure and main outcome obtained at the NFPs where stakeholders helped identify the main challenges and opportunities for the market surveillance of large industrial products, and expressed their views on the proposed INTAS methodology for compliance verification of power transformers.
The need for the INTAS project arises from the difficulty that MSAs face in establishing and verifying compliance with Ecodesign requirements for large industrial products.
With Ecodesign requirements in place, the performance of power transformers’ energy performance is no longer just a private contractual matter between the supplier and the purchaser. The supplier must also establish technical documentation on their product’s compliance before they are placed on the market and this documentation is subject to market surveillance checks.
During the course of the INTAS project, a cascaded and comprehensive set of available methodologies were assessed in practical “exercises” (overall 42 transformer units were investigated) with the help of MSAs, manufacturers of transformers, end-users like utilities and testing experts from independent laboratories, which we identified now as applicable for market surveillance of power transformers under INTAS: Documentation inspection of nameplates and technical documentation; Testing transformers at 3rd party laboratory; Testing transformers at manufacturer’s premises or in-situ at the end user’s premises; Witness testing at manufacturer’s premises in combination with Factory Acceptance Testing (FAT) assessment.
Although for transformers all options have been verified in general as applicable, reliable and cost-effective, depending on the product size, it was found that witness of factory acceptance tests (FATs) was the most affordable and the least disruptive and costly to suppliers. But there are still some open issues to be addressed to make these methodologies fully viable for MSAs.
