This paper aims to present a technique to estimate the losses of a dry-type air-core reactor (DTACR) assembled with one cylinder based on calorimetry principles while employing infrared thermography techniques. The technique is intuitive. practical. and easy to apply both in a laboratory and in the field. https://www.jmannino.com/mega-pick-NFL-San-Francisco-49ers-Zone-Block-iPhone-14-Pro-MagSafe-Case-p80213-quick-pick/
