Keterangan
\nTA = Transformator Arus<\/p>\n

Tf = Transformator Tegangan<\/p>\n

A = Amperemeter<\/p>\n

F = Frekuensimeter<\/p>\n

Cos (f ) = Sudut (untuk faktor daya)<\/p>\n

Sistem proteksi selain harus mengamankan peralatan instalasi terhadap gangguan, juga berfungsi melokalisir gangguan. Jika terjadi gangguan di suatu bagian instalasi, sistem proteksi hanya akan men-trip PMT yang berdekatan dengan gangguan dan tidak meluas.<\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"

Gangguan yang sering terjadi adalah hubung singkat antar phasa atau antara fasa dengan tanah dan keduanya. Gangguan hubung singkat dapat menimbulkan arus besar yang dapat merusak peralatan sehingga diperlukan sistem pengamanan atau sistem proteksi. Arus yang mengalir ke trip coil (TC) adalah arus searah dari baterai aki. Baterai aki mempunyai peran penting pada sistem proteksi, …<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[20],"tags":[4053,4056,4057,4062,4055,4058,4060,4059,4054,4061],"class_list":["post-4558","post","type-post","status-publish","format-standard","hentry","category-instalasi-pembangkit-listrik","tag-sistem-proteksi","tag-sistem-proteksi-adalah","tag-sistem-proteksi-generator","tag-sistem-proteksi-jaringan-distribusi","tag-sistem-proteksi-kebakaran","tag-sistem-proteksi-kebakaran-aktif","tag-sistem-proteksi-listrik","tag-sistem-proteksi-petir","tag-sistem-proteksi-tenaga-listrik","tag-sistem-proteksi-transformator"],"_links":{"self":[{"href":"https:\/\/www.tneutron.net\/blogs\/wp-json\/wp\/v2\/posts\/4558","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.tneutron.net\/blogs\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.tneutron.net\/blogs\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.tneutron.net\/blogs\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.tneutron.net\/blogs\/wp-json\/wp\/v2\/comments?post=4558"}],"version-history":[{"count":1,"href":"https:\/\/www.tneutron.net\/blogs\/wp-json\/wp\/v2\/posts\/4558\/revisions"}],"predecessor-version":[{"id":9024,"href":"https:\/\/www.tneutron.net\/blogs\/wp-json\/wp\/v2\/posts\/4558\/revisions\/9024"}],"wp:attachment":[{"href":"https:\/\/www.tneutron.net\/blogs\/wp-json\/wp\/v2\/media?parent=4558"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.tneutron.net\/blogs\/wp-json\/wp\/v2\/categories?post=4558"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.tneutron.net\/blogs\/wp-json\/wp\/v2\/tags?post=4558"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
