These tests have increased importance since the EU Ecodesign Directive per 1 July 2015 has put efficiency limits to power transformers that are sold on the European market. In this paper we present a series of measures to assure that power transformer efficiency tests performed by power transformer manufacturers are accurate and reliable. This includes the development of more accurate industrial loss measure&shy;ment systems (LMS), optimized LMS calibration approaches, and a reference system for on-site LMS calibration.</p> <p><em>This research is performed within the &ldquo;TrafoLoss&rdquo; EU joint research project, which has received funding from the EMPIR programme co-financed by the Participating States and from the European Union&rsquo;s Horizon 2020 research and innovation programme. Additional funding is received from the Dutch Ministry of Economic Affairs and Climate.</em></p> <p><em>Author&#39;s accepted version of a paper presented at the 5<sup>th</sup>&nbsp;International Colloquium &quot;Transformer Research and Asset Management&quot; (ICTRAM),&nbsp;Opatija / Croatia,&nbsp;October 9&nbsp;- 12, 2019</em></p> <p>&nbsp;</p></description> </descriptions> </resource>
