Water in the oil is in equilibrium with moisture in the solid insulation and lowers the breakdown voltage and accelerates the aging process. The exact determination of the moisture in the cellulose can only be done by sampling and subsequent Karl Fischer tritation. A modern method for determining moisture in insulation is PDC analysis.<\/p>\n<\/div><\/div>\n<\/div>\n\n<div class=\"et_pb_column_24 et_pb_column et_pb_column_1_3 et-last-child et_block_column et_pb_css_mix_blend_mode_passthrough\">\n<div class=\"et_pb_image_13 et_pb_image et_pb_module et_block_module\"><span class=\"et_pb_image_wrap\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.trafo-filtertechnik.de\/wp-content\/uploads\/2019\/11\/pic_kurve_wasser.gif\" width=\"300\" height=\"250\" srcset=\"https:\/\/www.trafo-filtertechnik.de\/wp-content\/uploads\/2019\/11\/pic_kurve_wasser.gif 300w\" sizes=\"(max-width: 300px) 100vw, 300px\" class=\"wp-image-204\" \/><\/span><\/div>\n<\/div>\n<\/div>\n\n<div class=\"et_pb_row_19 et_pb_row et_block_row\" id=\"transformer\">\n<div class=\"et_pb_column_25 et_pb_column et_pb_column_4_4 et-last-child et_block_column et_pb_css_mix_blend_mode_passthrough\">\n<div class=\"et_pb_divider_6 et_pb_divider et_pb_space et_pb_divider_position_center et_pb_module\"><div class=\"et_pb_divider_internal\"><\/div><\/div>\n<\/div>\n<\/div>\n\n<div class=\"et_pb_row_20 et_pb_row et_block_row\">\n<div class=\"et_pb_column_26 et_pb_column et_pb_column_4_4 et-last-child et_block_column et_pb_css_mix_blend_mode_passthrough\">\n<div class=\"et_pb_image_14 et_pb_image et_animated et_pb_module et_block_module\"><span class=\"et_pb_image_wrap\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.trafo-filtertechnik.de\/wp-content\/uploads\/2019\/11\/electrician_04-1.png\" width=\"25\" height=\"25\" srcset=\"https:\/\/www.trafo-filtertechnik.de\/wp-content\/uploads\/2019\/11\/electrician_04-1.png 25w\" sizes=\"(max-width: 25px) 100vw, 25px\" class=\"wp-image-54\" \/><\/span><\/div>\n\n<div class=\"et_pb_text_13 et_pb_text et_pb_bg_layout_light et_pb_module et_block_module\"><div class=\"et_pb_text_inner\"><h2>Transformer maintenance<\/h2>\n<\/div><\/div>\n<\/div>\n<\/div>\n\n<div class=\"et_pb_row_21 et_pb_row et_block_row\">\n<div class=\"et_pb_column_27 et_pb_column et_pb_column_2_3 et_block_column et_pb_css_mix_blend_mode_passthrough\">\n<div class=\"et_pb_text_14 et_pb_text et_pb_bg_layout_light et_pb_module et_block_module\"><div class=\"et_pb_text_inner\"><p>The most important elements of power distribution are transformers, these vary between distribution, machine, special and grid coupling transformers.<\/p>\n<p>In principle, all transformers consist of the following materials:<\/p>\n<ul>\n<li>Insulating materials such as pressboard<\/li>\n<li>Paper<\/li>\n<li>Wood and transformer oil used for insulation and cooling<\/li>\n<li>Electrical sheets<\/li>\n<li>Copper<\/li>\n<\/ul>\n<p>These materials are subject to natural aging during normal operation, which is highly dependent on the operating conditions. In normal operation, they are approx. 25 - 30 years, provided they are professionally maintained and cared for.<\/p>\n<p>However, during the course of a transformer's life, there are events that can be regarded as non-normal operation:<\/p>\n<ul>\n<li>e.g. overload, overvoltage and, due to overheating, further problems in cooling.<\/li>\n<\/ul>\n<p>These events accelerate the ageing of the materials. One of the most common causes of transformer malfunction is oil. To detect this in good time, it is essential to carry out regular oil checks. With early detection, countermeasures can be taken, which certainly does not prevent the aging process, but largely delays it.<\/p>\n<\/div><\/div>\n<\/div>\n\n<div class=\"et_pb_column_28 et_pb_column et_pb_column_1_3 et-last-child et_block_column et_pb_css_mix_blend_mode_passthrough\">\n<div class=\"et_pb_image_15 et_pb_image et_pb_module et_block_module\"><span class=\"et_pb_image_wrap\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.trafo-filtertechnik.de\/wp-content\/uploads\/2019\/11\/Kopie-von-PICT1115.jpg\" width=\"640\" height=\"480\" srcset=\"https:\/\/www.trafo-filtertechnik.de\/wp-content\/uploads\/2019\/11\/Kopie-von-PICT1115.jpg 640w, https:\/\/www.trafo-filtertechnik.de\/wp-content\/uploads\/2019\/11\/Kopie-von-PICT1115-480x360.jpg 480w\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) 640px, 100vw\" class=\"wp-image-212\" \/><\/span><\/div>\n<\/div>\n<\/div>\n\n<div class=\"et_pb_row_22 et_pb_row et_block_row\" id=\"safepoint\">\n<div class=\"et_pb_column_29 et_pb_column et_pb_column_4_4 et-last-child et_block_column et_pb_css_mix_blend_mode_passthrough\">\n<div class=\"et_pb_divider_7 et_pb_divider et_pb_space et_pb_divider_position_center et_pb_module\"><div class=\"et_pb_divider_internal\"><\/div><\/div>\n<\/div>\n<\/div>\n\n<div class=\"et_pb_row_23 et_pb_row et_block_row\">\n<div class=\"et_pb_column_30 et_pb_column et_pb_column_4_4 et-last-child et_block_column et_pb_css_mix_blend_mode_passthrough\">\n<div class=\"et_pb_image_16 et_pb_image et_animated et_pb_module et_block_module\"><span class=\"et_pb_image_wrap\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.trafo-filtertechnik.de\/wp-content\/uploads\/2019\/11\/electrician_04-1.png\" width=\"25\" height=\"25\" srcset=\"https:\/\/www.trafo-filtertechnik.de\/wp-content\/uploads\/2019\/11\/electrician_04-1.png 25w\" sizes=\"(max-width: 25px) 100vw, 25px\" class=\"wp-image-54\" \/><\/span><\/div>\n\n<div class=\"et_pb_text_15 et_pb_text et_pb_bg_layout_light et_pb_module et_block_module\"><div class=\"et_pb_text_inner\"><h2>Safepoint<\/h2>\n<\/div><\/div>\n<\/div>\n<\/div>\n\n<div class=\"et_pb_row_24 et_pb_row et_block_row\">\n<div class=\"et_pb_column_31 et_pb_column et_pb_column_2_3 et_block_column et_pb_css_mix_blend_mode_passthrough\">\n<div class=\"et_pb_text_16 et_pb_text et_pb_bg_layout_light et_pb_module et_block_module\"><div class=\"et_pb_text_inner\"><p>Our company uses the BORNACK-LATCHWAY stop structure for the inspection of large transformers and on construction sites.<\/p>\n<p>For the purpose of maintenance, revision and repair, transformers must be planned or unexpectedly climbed.

These guides can be passed over freely by the special running element without loosening the safety device. This increases the acceptance of the employees to use such a safety device.<\/p>\n<p>A safety shock absorber with tensioning device keeps the rope at a defined pretension and protects people and material from overloading in the event of a fall accident. The intermediate guides prevent the rope from sagging too much and thus avoid the risk of impact on the relatively close ground.<\/p>\n<\/div><\/div>\n<\/div>\n\n<div class=\"et_pb_column_32 et_pb_column et_pb_column_1_3 et-last-child et_block_column et_pb_css_mix_blend_mode_passthrough\">\n<div class=\"et_pb_image_17 et_pb_image et_pb_module et_block_module\"><span class=\"et_pb_image_wrap\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.trafo-filtertechnik.de\/wp-content\/uploads\/2019\/11\/bornack.gif\" width=\"150\" height=\"68\" srcset=\"https:\/\/www.trafo-filtertechnik.de\/wp-content\/uploads\/2019\/11\/bornack.gif 150w\" sizes=\"(max-width: 150px) 100vw, 150px\" class=\"wp-image-216\" \/><\/span><\/div>\n<\/div>\n<\/div>\n\n<div class=\"et_pb_row_25 et_pb_row et_block_row\">\n<div class=\"et_pb_column_33 et_pb_column et_pb_column_4_4 et-last-child et_block_column et_pb_css_mix_blend_mode_passthrough\">\n<div class=\"et_pb_divider_8 et_pb_divider et_pb_space et_pb_divider_position_center et_pb_module\"><div class=\"et_pb_divider_internal\"><\/div><\/div>\n<\/div>\n<\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"","protected":false},"author":1,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"open","template":"","meta":{"footnotes":""},"class_list":["post-509","page","type-page","status-publish","hentry"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.9 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Our services - Seifert Transformatorentechnik<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/www.trafo-filtertechnik.de\/en\/our-services\/\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Our services - Seifert Transformatorentechnik\" \/>\n<meta property=\"og:url\" content=\"https:\/\/www.trafo-filtertechnik.de\/en\/our-services\/\" \/>\n<meta property=\"og:site_name\" content=\"Seifert Transformatorentechnik\" \/>\n<meta property=\"article:modified_time\" content=\"2026-05-28T11:11:32+00:00\" \/>\n<meta name=\"twitter:card\" content=\"summary_large_image\" \/>\n<script type=\"application\/ld+json\" class=\"yoast-schema-graph\">{\"@context\":\"https:\\\/\\\/schema.org\",\"@graph\":[{\"@type\":\"WebPage\",\"@id\":\"https:\\\/\\\/www.trafo-filtertechnik.de\\\/en\\\/our-services\\\/\",\"url\":\"https:\\\/\\\/www.trafo-filtertechnik.de\\\/en\\\/our-services\\\/\",\"name\":\"Our services - Seifert Transformatorentechnik\",\"isPartOf\":{\"@id\":\"https:\\\/\\\/www.trafo-filtertechnik.de\\\/en\\\/#website\"},\"datePublished\":\"2019-11-16T14:50:13+00:00\",\"dateModified\":\"2026-05-28T11:11:32+00:00\",\"breadcrumb\":{\"@id\":\"https:\\\/\\\/www.trafo-filtertechnik.de\\\/en\\\/our-services\\\/#breadcrumb\"},\"inLanguage\":\"en-US\",\"potentialAction\":[{\"@type\":\"ReadAction\",\"target\":[\"https:\\\/\\\/www.trafo-filtertechnik.de\\\/en\\\/our-services\\\/\"]}]},{\"@type\":\"BreadcrumbList\",\"@id\":\"https:\\\/\\\/www.trafo-filtertechnik.de\\\/en\\\/our-services\\\/#breadcrumb\",\"itemListElement\":[{\"@type\":\"ListItem\",\"position\":1,\"name\":\"Startseite\",\"item\":\"https:\\\/\\\/www.trafo-filtertechnik.de\\\/en\\\/\"},{\"@type\":\"ListItem\",\"position\":2,\"name\":\"Our services\"}]},{\"@type\":\"WebSite\",\"@id\":\"https:\\\/\\\/www.trafo-filtertechnik.de\\\/en\\\/#website\",\"url\":\"https:\\\/\\\/www.trafo-filtertechnik.de\\\/en\\\/\",\"name\":\"Seifert Transformatorentechnik\",\"description\":\"Wartung &amp;
