During the various stages of progress, for assessing a wave energy device, it is convenient to carry out experimental testing that, opportunely, takes into account the realistic behaviour of the power take-off mechanism at a small scale. To successfully replicate and assess the power take-off, good practices need to be implemented aiming to correctly scale and evaluate the power take-off mechanism and its behaviour. The present paper aims to explore and propose solutions that can be applied for reproducing and assessing the power take-off element during experimental studies, namely experimental set-ups enhancements, calibration practices, and error estimation methods. A series of recommendations on how to practically organize and carry out experiments were identified and three case studies are briefly covered. It was found that, despite specific options that can be strictly technology-dependent, various recommendations could be universally applicable.<\/jats:p>","DOI":"10.3390\/jmse8090632","type":"journal-article","created":{"date-parts":[[2020,8,20]],"date-time":"2020-08-20T09:35:31Z","timestamp":1597916131000},"page":"632","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":44,"title":["Wave Energy Converter Power Take-Off System Scaling and Physical Modelling"],"prefix":"10.3390","volume":"8","author":[{"given":"Gianmaria","family":"Giannini","sequence":"first","affiliation":[{"name":"Department of Civil Engineering, Faculty of Engineering of the University of Porto (FEUP), 4200-465 Porto, Portugal"},{"name":"Interdisciplinary Centre of Marine and Environmental Research of the University of Porto (CIIMAR), 4200-465 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5252-324X","authenticated-orcid":false,"given":"Irina","family":"Temiz","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering, Uppsala University, P.O.
