By comparison, with the same rated power (1,000kVA each), the new transformers have a total power loss of only 8.29 kW per transformer &#8211; just under half.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">For our customer, this means the following:  <\/span><\/p>\n<p><span style=\"font-weight: 400;\">Continuous three-shift operation means a permanent load for the transformers. For the calculation we have assumed a permanent load of 60-70%. Calculated with an assumed electricity price of 0.10\u20ac\/kWh, this results in an enormous savings potential over a period of 20 years, as the following graphic illustrates.  <\/span><\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-f9edc50 elementor-widget elementor-widget-image\" data-id=\"f9edc50\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t<figure class=\"wp-caption\">\n\t\t\t\t\t\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"800\" height=\"532\" src=\"https:\/\/horstmann-schwarz.de\/wp-content\/uploads\/2021\/12\/Einsparpotential_unterschiedliche_Verlustklassen_Avangard-1024x681.png\" class=\"attachment-large size-large wp-image-6769\" alt=\"\" srcset=\"https:\/\/horstmann-schwarz.de\/wp-content\/uploads\/2021\/12\/Einsparpotential_unterschiedliche_Verlustklassen_Avangard-1024x681.png 1024w, https:\/\/horstmann-schwarz.de\/wp-content\/uploads\/2021\/12\/Einsparpotential_unterschiedliche_Verlustklassen_Avangard-300x199.png 300w, https:\/\/horstmann-schwarz.de\/wp-content\/uploads\/2021\/12\/Einsparpotential_unterschiedliche_Verlustklassen_Avangard-768x511.png 768w, https:\/\/horstmann-schwarz.de\/wp-content\/uploads\/2021\/12\/Einsparpotential_unterschiedliche_Verlustklassen_Avangard-1536x1021.png 1536w, https:\/\/horstmann-schwarz.de\/wp-content\/uploads\/2021\/12\/Einsparpotential_unterschiedliche_Verlustklassen_Avangard.png 1916w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/>\t\t\t\t\t\t\t\t\t\t\t<figcaption class=\"widget-image-caption wp-caption-text\"><\/figcaption>\n\t\t\t\t\t\t\t\t\t\t<\/figure>\n\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-992037f elementor-widget elementor-widget-text-editor\" data-id=\"992037f\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p><span style=\"font-weight: 400;\">The return on investment thus occurs even before half of the imputed service life of approx. 35-40 years of the new station.<\/span><\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-2637cf4 elementor-icon-list--layout-traditional elementor-list-item-link-full_width elementor-widget elementor-widget-icon-list\" data-id=\"2637cf4\" data-element_type=\"widget\" data-widget_type=\"icon-list.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<ul class=\"elementor-icon-list-items\">\n\t\t\t\t\t\t\t<li class=\"elementor-icon-list-item\">\n\t\t\t\t\t\t\t\t\t\t\t<span class=\"elementor-icon-list-icon\">\n\t\t\t\t\t\t\t<i aria-hidden=\"true\" class=\"fas fa-info-circle\"><\/i>\t\t\t\t\t\t<\/span>\n\t\t\t\t\t\t\t\t\t\t<span class=\"elementor-icon-list-text\">Transformer losses: The unavoidable losses of the transformers consist of short-circuit (load-dependent) and no-load (load-independent) losses. No-load losses are often also referred to as eddy current losses, hysteresis losses, or iron current losses.  <br>Short circuit losses are caused by the resistance of the coils. When a secondary current (load) flows, a voltage drop occurs and the windings of the coils heat up. The amount of losses increases quadratically with increasing load. The losses are also dependent on the transformer power. Before each transformer replacement, we therefore check the optimum operating point to determine the best possible transformer size for the required power.  <\/span>\n\t\t\t\t\t\t\t\t\t<\/li>\n\t\t\t\t\t\t<\/ul>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-7bbe512 elementor-widget elementor-widget-image\" data-id=\"7bbe512\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t<figure class=\"wp-caption\">\n\t\t\t\t\t\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"1192\" height=\"1472\" src=\"https:\/\/horstmann-schwarz.de\/wp-content\/uploads\/2021\/12\/Lastabha\u0308ngige_Verluste_Avangard.png\" class=\"attachment-full size-full wp-image-6770\" alt=\"\" srcset=\"https:\/\/horstmann-schwarz.de\/wp-content\/uploads\/2021\/12\/Lastabha\u0308ngige_Verluste_Avangard.png 1192w, https:\/\/horstmann-schwarz.de\/wp-content\/uploads\/2021\/12\/Lastabha\u0308ngige_Verluste_Avangard-243x300.png 243w, https:\/\/horstmann-schwarz.de\/wp-content\/uploads\/2021\/12\/Lastabha\u0308ngige_Verluste_Avangard-829x1024.png 829w, https:\/\/horstmann-schwarz.de\/wp-content\/uploads\/2021\/12\/Lastabha\u0308ngige_Verluste_Avangard-768x948.png 768w\" sizes=\"(max-width: 1192px) 100vw, 1192px\" \/>\t\t\t\t\t\t\t\t\t\t\t<figcaption class=\"widget-image-caption wp-caption-text\">Pv= load dependent power loss<\/figcaption>\n\t\t\t\t\t\t\t\t\t\t<\/figure>\n\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-05e0a09 elementor-widget elementor-widget-text-editor\" data-id=\"05e0a09\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p><span style=\"font-weight: 400;\">No-load losses, on the other hand, are caused by the constant remagnetization of the iron core. The transformer manufacturer can exert a positive influence through the quality of the core laminations and optimum transitions between the individual laminations. A good transition also optimizes noise emissions. The thickness of the plates also has an influence: Particularly thin rolled plates minimize the losses.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">&nbsp;<\/span><\/p>\n<p>Would you like to know how much savings potential is possible for your company with a modernized or new transformer station?
