It is crucial that the inside temperature of transformer buildings is higher than the outside temperature due to the operation of the transformer and the effect of ambient conditions. This issue may cause several problems such as additional transformer aging, losses, and moisture. The main purpose of this study is to decrease the inside temperature of transformer buildings; in other words, to prevent the inside temperature from being higher than the outside temperature. To realize this, it is recommended to apply a combined heat reduction technique by covering the outer surface with a reflective surface and use a low-emitting material on the inner surface. The relevant results of the practical evidence in this manner are presented in detail at a distribution system in Turkey with different climate and loading conditions in the summertime.<\/jats:p>","DOI":"10.3390\/electronics9122127","type":"journal-article","created":{"date-parts":[[2020,12,13]],"date-time":"2020-12-13T20:56:57Z","timestamp":1607893017000},"page":"2127","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Practical Evidence-Based Evaluation of a Combined Heat Reduction Technique for Power Transformer Buildings"],"prefix":"10.3390","volume":"9","author":[{"given":"\u0130lker","family":"Dursun","sequence":"first","affiliation":[{"name":"Department of Electrical and Electronics Engineering, Sakarya University of Applied Sciences, 54700 Sakarya, Turkey"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1085-0474","authenticated-orcid":false,"given":"S\u0131tk\u0131","family":"G\u00fcner","sequence":"additional","affiliation":[{"name":"Department of Electrical and Electronics Engineering, Faculty of Engineering and Architecture, Istanbul Arel University, 34537 Istanbul, Turkey"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9451-4218","authenticated-orcid":false,"given":"\u0130brahim","family":"\u015eeng\u00f6r","sequence":"additional","affiliation":[{"name":"Department of Electrical and Electronics Engineering, Faculty of Engineering and Architecture, \u0130zmir Katip \u00c7elebi University, 35620 \u0130zmir, Turkey"}]},{"given":"Ay\u015fe K\u00fcbra","family":"Ereno\u011flu","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering, Faculty of Electric-Electronics, Yildiz Technical University Davutpasa Campus, Esenler, 34220 Istanbul, Turkey"}]},{"given":"Ozan","family":"Erdin\u00e7","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering, Faculty of Electric-Electronics, Yildiz Technical University Davutpasa Campus, Esenler, 34220 Istanbul, Turkey"}]},{"given":"Jo\u00e3o P.
