The Role of Single Point Grounding of Iron Core and the Anomaly of Multiple Point Groundings<\/h1>\n

\"undefined\"<\/a><\/p>\n

In the electrical and electronic industry, the application of ground protection is very important. Iron core single point grounding is the most commonly used ground protection method, which requires a special grounding bar and appropriate grounding resistance to be connected to the neutral point of the transformer. Its role is to prevent the short circuit of equipment, improve the safety performance, reduce the electromagnetic radiation, and prevent the electromagnetic interference from outside.<\/p>\n

In addition, it can also reduce the neutral current, reduce the harmonic interference generated by other loads and make the current more balanced. The application of single point grounding has certain requirements and standards, and only when the requirements of single point grounding can be met, the safety performance and normal operation of the system can be ensured.<\/p>\n

At the same time, special attention should be paid to the situation of multiple point groundings, which is an abnormal phenomenon. On the one hand, the grounding resistance is too low, resulting in excessive leakage current, which may cause the transformer to be overloaded. On the other hand, the electromagnetic interference will increase, which will affect the normal operation of the electrical equipment.<\/p>\n

Therefore, in the actual application, when the single point grounding is installed and used, the technicians should pay close attention to the performance and the standard requirements, strictly control the single point grounding resistance requirements, avoid the multiple point grounding and ensure the safe operation of the power system.<\/p>\n

Its role is to prevent the short circuit of equipment, improve the safety performance, reduce the electromagnetic radiation, and prevent the electromagnetic interference from outside.","breadcrumb":{"@id":"https:\/\/www.lstransformer.com\/the-role-of-single-point-grounding-of-iron-core-and-the-anomaly-of-multiple-point-groundings\/#breadcrumb"},"inLanguage":"fr-FR","potentialAction":[{"@type":"ReadAction","target":["https:\/\/www.lstransformer.com\/the-role-of-single-point-grounding-of-iron-core-and-the-anomaly-of-multiple-point-groundings\/"]}]},{"@type":"ImageObject","inLanguage":"fr-FR","@id":"https:\/\/www.lstransformer.com\/the-role-of-single-point-grounding-of-iron-core-and-the-anomaly-of-multiple-point-groundings\/#primaryimage","url":"https:\/\/www.lstransformer.com\/wp-content\/uploads\/2026\/07\/1742179423424134.png","contentUrl":"https:\/\/www.lstransformer.com\/wp-content\/uploads\/2026\/07\/1742179423424134.png","width":370,"height":276},{"@type":"BreadcrumbList","@id":"https:\/\/www.lstransformer.com\/the-role-of-single-point-grounding-of-iron-core-and-the-anomaly-of-multiple-point-groundings\/#breadcrumb","itemListElement":[{"@type":"ListItem","position":1,"name":"\u9996\u9875","item":"https:\/\/www.lstransformer.com\/"},{"@type":"ListItem","position":2,"name":"The Role of Single Point Grounding of Iron Core and the Anomaly of Multiple Point Groundings"}]},{"@type":"WebSite","@id":"https:\/\/www.lstransformer.com\/#website","url":"https:\/\/www.lstransformer.com\/","name":"LS transformateur de puissance, r\u00e9acteur de Ligne \u00e0 Haute tension transformateur d'Huile de transformateur immerg\u00e9-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":"fr-FR"},{"@type":"Organization","@id":"https:\/\/www.lstransformer.com\/#organization","name":"LS transformateur de puissance, r\u00e9acteur de Ligne \u00e0 Haute tension transformateur d'Huile de transformateur immerg\u00e9-CHANGSHA LUSHAN ELECTRONIC TECHNOLOGY CO.,LTD","url":"https:\/\/www.lstransformer.com\/","logo":{"@type":"ImageObject","inLanguage":"fr-FR","@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":"fr-FR","@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\/fr\/author\/369703005\/"}]}},"_links":{"self":[{"href":"https:\/\/www.lstransformer.com\/fr\/wp-json\/wp\/v2\/posts\/1396","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.lstransformer.com\/fr\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.lstransformer.com\/fr\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.lstransformer.com\/fr\/wp-json\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/www.lstransformer.com\/fr\/wp-json\/wp\/v2\/comments?post=1396"}],"version-history":[{"count":4,"href":"https:\/\/www.lstransformer.com\/fr\/wp-json\/wp\/v2\/posts\/1396\/revisions"}],"predecessor-version":[{"id":6696,"href":"https:\/\/www.lstransformer.com\/fr\/wp-json\/wp\/v2\/posts\/1396\/revisions\/6696"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.lstransformer.com\/fr\/wp-json\/wp\/v2\/media\/2500"}],"wp:attachment":[{"href":"https:\/\/www.lstransformer.com\/fr\/wp-json\/wp\/v2\/media?parent=1396"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.lstransformer.com\/fr\/wp-json\/wp\/v2\/categories?post=1396"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.lstransformer.com\/fr\/wp-json\/wp\/v2\/tags?post=1396"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
