If the oil dielectric strength decreases from the initial value \u00a0 KV\/25 65 mm to 55 kV \/ 2.5 mm, or if more than 4 days after \u00a0 filled with oil, the oil must be replaced.<\/p>\n 2) Application of Voltage<\/strong> Test probability of failure can be obtained in two ways: Failure Analysis of Transformer Oil<\/strong> 1) Equipment trial<\/strong> 2) The cleaning procedure<\/strong> 3) Electrical Testing<\/strong> Various kinds of electrode were used for this test is to obtain test results in case of failure of transformer oil pressure oil volume, uniform and non-uniform field. 1) Transformer Oil Processing Dielectric strength of the transformer oil is strongly influenced by processing and testing conditions, as it determines the quality of \u00a0 transformer oil …<\/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":[4628,4631,4627,4629,4626,4625,4622,4630,4623,4624],"class_list":["post-4543","post","type-post","status-publish","format-standard","hentry","category-instalasi-pembangkit-listrik","tag-account-creation-failed-transformers-universe","tag-asus-transformer-failed-to-connect","tag-asus-transformer-failed-to-connect-to-network","tag-asus-transformer-failed-to-update-my-location","tag-datastage-transformer-failed-to-load-the-library","tag-failed-output-transformer","tag-failed-transformer","tag-lighting-transformer-failed","tag-transformerconfigurationexception-failed-to-compile-stylesheet","tag-transformers-failed-experiment"],"_links":{"self":[{"href":"https:\/\/www.tneutron.net\/blogs\/wp-json\/wp\/v2\/posts\/4543","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=4543"}],"version-history":[{"count":1,"href":"https:\/\/www.tneutron.net\/blogs\/wp-json\/wp\/v2\/posts\/4543\/revisions"}],"predecessor-version":[{"id":9113,"href":"https:\/\/www.tneutron.net\/blogs\/wp-json\/wp\/v2\/posts\/4543\/revisions\/9113"}],"wp:attachment":[{"href":"https:\/\/www.tneutron.net\/blogs\/wp-json\/wp\/v2\/media?parent=4543"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.tneutron.net\/blogs\/wp-json\/wp\/v2\/categories?post=4543"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.tneutron.net\/blogs\/wp-json\/wp\/v2\/tags?post=4543"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
\nDielectric strength of the transformer oil is strongly influenced by processing and testing conditions, as it determines the quality of \u00a0 transformer oil during testing. The nature of the oil will be lost \u00a0 through moisture, gases, impurities, and charging into \u00a0 testing tank.<\/p>\n
\nAC voltage and impulse voltage is usually used in testing, testing with AC voltage can be obtained by raising method Steady voltage and withstand voltage method, with increased from 5 to 10% step, from 60% of the expected breakdown voltage. Impulse voltage created by the up and down method from 5 to 10% of the expected breakdown voltage step.<\/p>\n
\n\u300dAC voltage riding at a constant speed 3kV\/sec failure. This procedure is repeated up to 500 times in 1 minute intervals.
\n\u300dVoltage band between 0 to 100% breakdown voltage, which, divided in several levels. AC voltage was applied for 1 minute 20 times each voltage level, while the impulse voltage was applied 20 times for each voltage level.<\/p>\n
\nSome factors affecting the dielectric strength of the transformer oil, among others, the phenomenon of stabilization, treatment before the use of oil and electrodes, the effect of the speed of the oil, the effect of parallel capacity of the test cell, and the effect of the electrode area and gap distance.<\/p>\n
\nTo understand the analysis done first glimpse of reviewing the experimental procedures and tools used in transformer oil failure. There are 3 types of electrodes are commonly used in the experiment, namely mild steel electrodes and a small (10 mm diameter), brass electrode-Bruce profile with broad flat areas and coaxial cylindrical steel electrodes with a gap distance over a wide range.<\/p>\n
\nFirst electrode preparation was washed with \u00a0 trichlorethylene, penggosongan surfaces are standard with \u00a0 1000 grade silicon carbide paper, then washed in a mixture of water \u00a0 hot and soapy solution, drying and removal of dust with \u00a0 synthetic rubber foam, rinse with hot water and distilled water.
\nThe electrodes were dried in air different cabinet sectional and finally rubbed with lens tissue lint with \u00a0 acetone wear after wear trichlorethylene. Rest \u00a0 connection electrode is washed with hot water and soap solution and \u00a0 rinsed in accordance with the above procedure each time after testing<\/p>\n
\nAll testing is done with a sine wave ac voltage \u00a0 with a frequency of 5 Hz. Applied voltage is increased \u00a0 uniform in all tests with an average price of 2 kV \/ sec. \u00a0 A CB is connected to the primary side of the transformer with a purpose \u00a0 to decide if the fault current is allowed to flow disturbances \u00a0 too long will cause carbonization and will perforate \u00a0 electrodes.<\/p>\n","protected":false},"excerpt":{"rendered":"
