standard kVA rating used for distribution in three-phase electricity in North America is 112.5 kVA. With this number and the National Electrical Code requirements concerning dry type installations, its prevalence becomes easy to understand. This may come as an unexpected fact, but two transformers that share the same kVA and voltage ratio can differ significantly in many characteristics, for example, in the volume and weight being hundreds of pounds apart. In this article, I provide you with the exact specifications and explore the factors that have a significant impact on transformer sizes. In brief, a 3-phase transformer rated at 112.5 kVA is around 50\u201362 inches in width, 44\u201364 inches [&hellip;]<\/p>\n","protected":false},"author":2,"featured_media":11694,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[1],"tags":[],"class_list":["post-11693","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-blog"],"blocksy_meta":[],"acf":[],"_links":{"self":[{"href":"https:\/\/subian-electric.com\/ja\/wp-json\/wp\/v2\/posts\/11693","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/subian-electric.com\/ja\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/subian-electric.com\/ja\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/subian-electric.com\/ja\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/subian-electric.com\/ja\/wp-json\/wp\/v2\/comments?post=11693"}],"version-history":[{"count":2,"href":"https:\/\/subian-electric.com\/ja\/wp-json\/wp\/v2\/posts\/11693\/revisions"}],"predecessor-version":[{"id":11699,"href":"https:\/\/subian-electric.com\/ja\/wp-json\/wp\/v2\/posts\/11693\/revisions\/11699"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/subian-electric.com\/ja\/wp-json\/wp\/v2\/media\/11694"}],"wp:attachment":[{"href":"https:\/\/subian-electric.com\/ja\/wp-json\/wp\/v2\/media?parent=11693"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/subian-electric.com\/ja\/wp-json\/wp\/v2\/categories?post=11693"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/subian-electric.com\/ja\/wp-json\/wp\/v2\/tags?post=11693"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
