By measuring these two parameters, it is possible to detect failures, related to transformer core or windings, that cannot be spotted by measuring only the turns ratio.<\/p>\n<p>The instrument can output a maximum test voltage of 40 V AC for testing the turns ratio of distribution transformers, but it can also generate a very low voltage of 1 V AC which is necessary for the turns ratio verification of most current transformers. By measuring the phase angle, the polarity of instrument transformers can be checked.<\/p>\n<h2>Applications include:<\/h2>\n<ul>\n<li>Turns ratio measurement of distribution transformers<\/li>\n<li>Turns ratio verification of instrument transformers<\/li>\n<li>Turns ratio deviation calculation<\/li>\n<li>Excitation current measurement of distribution and instrument transformers<\/li>\n<li>Phase angle measurement of distribution and instrument transformers<\/li>\n<li>Polarity check of instrument transformers<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p>TRT-H is powered by an internal Li-Ion battery. Up to 100 tests can be performed with a fully charged battery. The battery charging time is 2.5 hours.<\/p>\n<p>&nbsp;<\/p>\n<h2 id=\"tablepress-42-name\" class=\"tablepress-table-name tablepress-table-name-id-42\">TRT-H Series Specification Highlights<\/h2>\n\n<table id=\"tablepress-42\" class=\"tablepress tablepress-id-42\" aria-labelledby=\"tablepress-42-name\">\n<tbody class=\"row-striping row-hover\">\n<tr class=\"row-1\">\n\t<td class=\"column-1\"><strong>Generated Voltage<\/strong><\/td><td class=\"column-2\">Up to 40 V AC for turns ratio test<\/td>\n<\/tr>\n<tr class=\"row-2\">\n\t<td class=\"column-1\"><strong>Weight<\/strong><\/td><td class=\"column-2\">1.4 kg \/ 3.1 lbs<\/td>\n<\/tr>\n<tr class=\"row-3\">\n\t<td class=\"column-1\"><strong>Battery<\/strong><\/td><td class=\"column-2\">Up to 100 tests<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<!-- #tablepress-42 from cache -->\n<h2>Datasheet:<\/h2>\n<div class='w3eden'><!-- WPDM Link Template: Default Template -->\n\n<div class=\"link-template-default card mb-2\">\n    <div class=\"card-body\">\n        <div class=\"media\">\n            <div class=\"mr-3 img-48\"><img decoding=\"async\" class=\"wpdm_icon\" alt=\"Icon\" src=\"https:\/\/testnordic.se\/wp-content\/plugins\/download-manager\/assets\/file-type-icons\/pdf.svg\" \/><\/div>\n            <div class=\"media-body\">\n                <h3 class=\"package-title\"><a href='https:\/\/testnordic.se\/en\/download\/trt-h-serien\/'>TRT-H Series Datasheet<\/a><\/h3>\n                <div class=\"text-muted text-small\"><i class=\"fas fa-copy\"><\/i> 1 file(s) <i class=\"fas fa-hdd ml-3\"><\/i> 452.47 KB<\/div>\n            <\/div>\n            <div class=\"ml-3\">\n                <a class='wpdm-download-link download-on-click btn btn-primary ' rel='nofollow' href='#' data-downloadurl=\"https:\/\/testnordic.se\/en\/download\/trt-h-serien\/?wpdmdl=14522&refresh=6a5742ad677e91784103597\">Download<\/a>\n            <\/div>\n        <\/div>\n    <\/div>\n<\/div>\n\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p><strong>Turns Ratio Tester TRT-H Series<\/strong><\/p>\n<p><strong>Handheld turns ratio tester TRT-H<\/strong> is DV Power single-phase instrument specially designed for measuring transformer turns ratio of single-phase and three-phase transformers.<\/p>\n<p><img decoding=\"async\" class=\"alignnone size-full wp-image-9259\" src=\"https:\/\/testnordic.com\/wp-content\/uploads\/2022\/02\/Logo-2023-08-14.jpg\" alt=\"\" width=\"202\" height=\"53\" srcset=\"https:\/\/testnordic.se\/wp-content\/uploads\/2022\/02\/Logo-2023-08-14.jpg 202w, https:\/\/testnordic.se\/wp-content\/uploads\/2022\/02\/Logo-2023-08-14-64x17.jpg 64w\" sizes=\"(max-width: 202px) 100vw, 202px\" \/><\/p>\n","protected":false},"featured_media":14533,"template":"","meta":{"_kad_post_transparent":"","_kad_post_title":"","_kad_post_layout":"","_kad_post_sidebar_id":"","_kad_post_content_style":"","_kad_post_vertical_padding":"","_kad_post_feature":"","_kad_post_feature_position":"","_kad_post_header":false,"_kad_post_footer":false,"_kad_post_classname":""},"product_brand":[],"product_cat":[303],"product_tag":[],"yst_prominent_words":[],"class_list":{"0":"post-14528","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-turn-ratio","8":"first","9":"instock","10":"taxable","11":"shipping-taxable","12":"product-type-simple","13":"entry","14":"content-bg","15":"loop-entry"},"_links":{"self":[{"href":"https:\/\/testnordic.se\/en\/wp-json\/wp\/v2\/product\/14528","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/testnordic.se\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/testnordic.se\/en\/wp-json\/wp\/v2\/types\/product"}],"version-history":[{"count":2,"href":"https:\/\/testnordic.se\/en\/wp-json\/wp\/v2\/product\/14528\/revisions"}],"predecessor-version":[{"id":14539,"href":"https:\/\/testnordic.se\/en\/wp-json\/wp\/v2\/product\/14528\/revisions\/14539"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/testnordic.se\/en\/wp-json\/wp\/v2\/media\/14533"}],"wp:attachment":[{"href":"https:\/\/testnordic.se\/en\/wp-json\/wp\/v2\/media?parent=14528"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/testnordic.se\/en\/wp-json\/wp\/v2\/product_brand?post=14528"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/testnordic.se\/en\/wp-json\/wp\/v2\/product_cat?post=14528"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/testnordic.se\/en\/wp-json\/wp\/v2\/product_tag?post=14528"},{"taxonomy":"yst_prominent_words","embeddable":true,"href":"https:\/\/testnordic.se\/en\/wp-json\/wp\/v2\/yst_prominent_words?post=14528"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
