This document supersedes IEEE Std 28-1972 (ANSI C62.1-1971) and revises many portions of the previous edition. Three new significant design tests have been added to determine: (1) The highest 1.2 x 50 standard impulse which the surge arrester will allow without sparkover (2) The effect of external contamination on sparkover (3) Surge arrester disconnector characteristics Additional substantive changes include: (1) New definition of prorated section (2) Revision of Table 1 to include a 25 kV distribution surge arrester and special ratings for rotating machine protection (3) Increase in maximum rate-of-rise for front-of-wave sparkover test (4) Expanded range of currents in the discharge voltage test (5) Reduced high current test for station surge arresters to 65 kA (6) Expanded Table 4 to include test values for 550 kV and 800 kV system surge arresters (7) General revision of pressure-relief test<\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>ANSI\/IEEE Standard for Surge Arresters for Alternating Current Power Circuits<\/b><\/p>\n<table class=\"shortdes-table\" style=\"width: 100%\" border=\"0\" cellspacing=\"0\" cellpadding=\"0\">\n<tbody>\n<tr>\n<td>Published By<\/td>\n<td>Publication Date<\/td>\n<td>Number of Pages<\/td>\n<\/tr>\n<tr>\n<td><a href=\"https:\/\/pdfstandards.shop\/product-category\/publishers\/ieee\/\"><b>IEEE<\/b><\/a><\/td>\n<td>1974<\/td>\n<td>28<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"featured_media":147770,"template":"","meta":{"rank_math_lock_modified_date":false,"ep_exclude_from_search":false},"product_cat":[2644],"product_tag":[],"class_list":{"0":"post-147768","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-ieee","8":"first","9":"instock","10":"sold-individually","11":"shipping-taxable","12":"purchasable","13":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product\/147768","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media\/147770"}],"wp:attachment":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media?parent=147768"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_cat?post=147768"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_tag?post=147768"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
