A solar transformer can run hottest when a photovoltaic plant is producing near its maximum output, but a high temperature alarm does not automatically prove that the transformer is undersized. Peak generation can coincide with high ambient temperature, reduced cooling margin, reactive-power duty, harmonic losses or a local connection problem. The useful question is not […]<\/p>\n","protected":false},"author":1,"featured_media":808,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[111,114,110,113,75,112],"class_list":["post-1456","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-blog","tag-inverter-duty-transformer","tag-pv-power-systems","tag-solar-power-plant","tag-solar-transformer","tag-transformer-cooling","tag-transformer-overheating"],"_links":{"self":[{"href":"https:\/\/lanshanelectric.com\/vi\/wp-json\/wp\/v2\/posts\/1456","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/lanshanelectric.com\/vi\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/lanshanelectric.com\/vi\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/lanshanelectric.com\/vi\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/lanshanelectric.com\/vi\/wp-json\/wp\/v2\/comments?post=1456"}],"version-history":[{"count":1,"href":"https:\/\/lanshanelectric.com\/vi\/wp-json\/wp\/v2\/posts\/1456\/revisions"}],"predecessor-version":[{"id":1457,"href":"https:\/\/lanshanelectric.com\/vi\/wp-json\/wp\/v2\/posts\/1456\/revisions\/1457"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/lanshanelectric.com\/vi\/wp-json\/wp\/v2\/media\/808"}],"wp:attachment":[{"href":"https:\/\/lanshanelectric.com\/vi\/wp-json\/wp\/v2\/media?parent=1456"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/lanshanelectric.com\/vi\/wp-json\/wp\/v2\/categories?post=1456"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/lanshanelectric.com\/vi\/wp-json\/wp\/v2\/tags?post=1456"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
