          Field failure cost: An undetected vacuum leak on a 24KV VCB led to failure to interrupt a short circuit. This substation outage cost our utility company more than $200,000, and we missed it due to our testing procedures. \u2013 Maintenance engineer, regional utility company. Testing a VCB breaker is not the same as testing a low voltage circuit breaker or MCB. VCBs operate at high\/medium voltage levels (typically between 12 kV and 24 kV) and utilize the ability of the vacuum interrupter to operate correctly. In 2025, with the automation of electrical networks being implemented, it is necessary to have specific equipment available to ensure proper functioning of VCBs, which […]<\/p>\n","protected":false},"author":1,"featured_media":485,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[1],"tags":[],"class_list":["post-482","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-blog"],"blocksy_meta":[],"acf":[],"_links":{"self":[{"href":"https:\/\/benlongkj.com\/ja\/wp-json\/wp\/v2\/posts\/482","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/benlongkj.com\/ja\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/benlongkj.com\/ja\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/benlongkj.com\/ja\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/benlongkj.com\/ja\/wp-json\/wp\/v2\/comments?post=482"}],"version-history":[{"count":3,"href":"https:\/\/benlongkj.com\/ja\/wp-json\/wp\/v2\/posts\/482\/revisions"}],"predecessor-version":[{"id":489,"href":"https:\/\/benlongkj.com\/ja\/wp-json\/wp\/v2\/posts\/482\/revisions\/489"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/benlongkj.com\/ja\/wp-json\/wp\/v2\/media\/485"}],"wp:attachment":[{"href":"https:\/\/benlongkj.com\/ja\/wp-json\/wp\/v2\/media?parent=482"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/benlongkj.com\/ja\/wp-json\/wp\/v2\/categories?post=482"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/benlongkj.com\/ja\/wp-json\/wp\/v2\/tags?post=482"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
