What are the\u00a0Hazards of\u00a0a\u00a0Sudden\u00a0Short\u00a0Circuit to\u00a0a\u00a0Transformer?<\/b><\/h1>\n

When a sudden short circuit occurs at the secondary terminals of a transformer while rated voltage is applied to the primary side, the maximum value of the short-circuit current can reach 20 to 30 times the rated current amplitude. The maximum value of the short-circuit current is related to the phase angle at the moment of the short circuit, and the multiple of the rated current depends on the short-circuit impedance of the transformer. The smaller the impedance, the larger the multiple. The hazards that the sudden short-circuit current poses to the transformer windings include:<\/p>\n

The windings may be subjected to powerful electromagnetic forces, which could potentially cause damage.<\/p>\n

The windings may experience severe heating.<\/p>\n

It is generally stipulated that a transformer should be able to withstand an impact of short-circuit current (steady-state value) up to 25 times the rated current.<\/p>\n

The maximum value of the short-circuit current is related to the phase angle at the moment of the short circuit, and the multiple of the rated current depends on the short-circuit impedance of the transformer. The smaller the impedance, the larger the multiple. The hazards that the sudden short-circuit current poses to the transformer windings include:","breadcrumb":{"@id":"https:\/\/www.lstransformer.com\/what-are-thehazards-ofa-suddenshortcircuit-toa-transformer\/#breadcrumb"},"inLanguage":"de","potentialAction":[{"@type":"ReadAction","target":["https:\/\/www.lstransformer.com\/what-are-thehazards-ofa-suddenshortcircuit-toa-transformer\/"]}]},{"@type":"ImageObject","inLanguage":"de","@id":"https:\/\/www.lstransformer.com\/what-are-thehazards-ofa-suddenshortcircuit-toa-transformer\/#primaryimage","url":"https:\/\/www.lstransformer.com\/wp-content\/uploads\/2026\/07\/1742019268877393.png","contentUrl":"https:\/\/www.lstransformer.com\/wp-content\/uploads\/2026\/07\/1742019268877393.png","width":370,"height":276},{"@type":"BreadcrumbList","@id":"https:\/\/www.lstransformer.com\/what-are-thehazards-ofa-suddenshortcircuit-toa-transformer\/#breadcrumb","itemListElement":[{"@type":"ListItem","position":1,"name":"\u9996\u9875","item":"https:\/\/www.lstransformer.com\/"},{"@type":"ListItem","position":2,"name":"What are the Hazards of a Sudden Short Circuit to a Transformer?"}]},{"@type":"WebSite","@id":"https:\/\/www.lstransformer.com\/#website","url":"https:\/\/www.lstransformer.com\/","name":"LS power Transformator, die Linie Reaktor, Hohe-Spannung Transformator, \u00d6l-eingetaucht Transformator-CHANGSHA LUSHAN ELECTRONIC TECHNOLOGY CO.,LTD","description":"","publisher":{"@id":"https:\/\/www.lstransformer.com\/#organization"},"potentialAction":[{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https:\/\/www.lstransformer.com\/?s={search_term_string}"},"query-input":{"@type":"PropertyValueSpecification","valueRequired":true,"valueName":"search_term_string"}}],"inLanguage":"de"},{"@type":"Organization","@id":"https:\/\/www.lstransformer.com\/#organization","name":"LS power Transformator, die Linie Reaktor, Hohe-Spannung Transformator, \u00d6l-eingetaucht Transformator-CHANGSHA LUSHAN ELECTRONIC TECHNOLOGY CO.,LTD","url":"https:\/\/www.lstransformer.com\/","logo":{"@type":"ImageObject","inLanguage":"de","@id":"https:\/\/www.lstransformer.com\/#\/schema\/logo\/image\/","url":"https:\/\/www.lstransformer.com\/wp-content\/uploads\/2026\/06\/cropped-7e09bd7bad9c830e0d75b8487b0d77c3-1.webp","contentUrl":"https:\/\/www.lstransformer.com\/wp-content\/uploads\/2026\/06\/cropped-7e09bd7bad9c830e0d75b8487b0d77c3-1.webp","width":760,"height":202,"caption":"LS power transformer, Line reactor, High-voltage transformer, Oil-immersed transformer-CHANGSHA LUSHAN ELECTRONIC TECHNOLOGY CO.,LTD"},"image":{"@id":"https:\/\/www.lstransformer.com\/#\/schema\/logo\/image\/"}},{"@type":"Person","@id":"https:\/\/www.lstransformer.com\/#\/schema\/person\/674089c15f4857c19a997f886816d289","name":"369703005","image":{"@type":"ImageObject","inLanguage":"de","@id":"https:\/\/secure.gravatar.com\/avatar\/dcaa0e47cd7b6c99ffdd80f5772032ed2d2591b5b8e7b905e5fd87a850954248?s=96&d=mm&r=g","url":"https:\/\/secure.gravatar.com\/avatar\/dcaa0e47cd7b6c99ffdd80f5772032ed2d2591b5b8e7b905e5fd87a850954248?s=96&d=mm&r=g","contentUrl":"https:\/\/secure.gravatar.com\/avatar\/dcaa0e47cd7b6c99ffdd80f5772032ed2d2591b5b8e7b905e5fd87a850954248?s=96&d=mm&r=g","caption":"369703005"},"url":"https:\/\/www.lstransformer.com\/de\/author\/369703005\/"}]}},"_links":{"self":[{"href":"https:\/\/www.lstransformer.com\/de\/wp-json\/wp\/v2\/posts\/1309","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.lstransformer.com\/de\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.lstransformer.com\/de\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.lstransformer.com\/de\/wp-json\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/www.lstransformer.com\/de\/wp-json\/wp\/v2\/comments?post=1309"}],"version-history":[{"count":7,"href":"https:\/\/www.lstransformer.com\/de\/wp-json\/wp\/v2\/posts\/1309\/revisions"}],"predecessor-version":[{"id":7113,"href":"https:\/\/www.lstransformer.com\/de\/wp-json\/wp\/v2\/posts\/1309\/revisions\/7113"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.lstransformer.com\/de\/wp-json\/wp\/v2\/media\/4178"}],"wp:attachment":[{"href":"https:\/\/www.lstransformer.com\/de\/wp-json\/wp\/v2\/media?parent=1309"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.lstransformer.com\/de\/wp-json\/wp\/v2\/categories?post=1309"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.lstransformer.com\/de\/wp-json\/wp\/v2\/tags?post=1309"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
