utility engineer located in the north of Canada is designing a specification for a 25 MVA transformer that will operate in a substation with temperature levels going below -40\u00b0C during the month of January. The transformers have large cooling devices, their tank is specially constructed to withstand the heavy wind and snow loadings, so the only thing bothering the engineer is the type of oil utilized for the tank. The person knows what does it mean to select the wrong transformer oil for operation in cold climate. The oil will thicken when temperatures drop, the pump will start cavitating and the oil will stop flowing through the cooling devices, [&hellip;]<\/p>\n","protected":false},"author":3,"featured_media":10590,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[77],"tags":[],"class_list":["post-10589","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-news"],"blocksy_meta":[],"acf":[],"_links":{"self":[{"href":"https:\/\/subian-electric.com\/ja\/wp-json\/wp\/v2\/posts\/10589","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\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/subian-electric.com\/ja\/wp-json\/wp\/v2\/comments?post=10589"}],"version-history":[{"count":3,"href":"https:\/\/subian-electric.com\/ja\/wp-json\/wp\/v2\/posts\/10589\/revisions"}],"predecessor-version":[{"id":11103,"href":"https:\/\/subian-electric.com\/ja\/wp-json\/wp\/v2\/posts\/10589\/revisions\/11103"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/subian-electric.com\/ja\/wp-json\/wp\/v2\/media\/10590"}],"wp:attachment":[{"href":"https:\/\/subian-electric.com\/ja\/wp-json\/wp\/v2\/media?parent=10589"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/subian-electric.com\/ja\/wp-json\/wp\/v2\/categories?post=10589"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/subian-electric.com\/ja\/wp-json\/wp\/v2\/tags?post=10589"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
