The transformer connects these two voltage levels and allows power to flow between the energy storage system and the electrical network during charging and discharging.<\/p>\n<p class=\"isSelectedEnd\">A typical BESS power structure may look like:<\/p>\n<p class=\"isSelectedEnd\"><strong>Battery \u2192 BMS \u2192 PCS \u2192 Transformer \u2192 Grid or AC Load<\/strong><\/p>\n<p class=\"isSelectedEnd\">During charging, AC power from the grid is converted by the PCS and stored in the battery. During discharge, the battery supplies DC power to the PCS, which converts it back to AC before the transformer raises or matches the voltage for the grid or facility.<\/p>\n<p class=\"isSelectedEnd\">For this reason, the transformer must be selected according to the electrical characteristics of the PCS and the complete BESS application rather than only the battery capacity.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"1_Determine_the_Required_Transformer_Capacity\"><\/span>1. Determine the Required Transformer Capacity<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p class=\"isSelectedEnd\">The first step is to determine the required transformer <strong>kVA rating<\/strong>.<\/p>\n<p class=\"isSelectedEnd\">A common starting point is to calculate the maximum AC power handled by the PCS and then consider power factor, efficiency, load profile and future expansion.<\/p>\n<p class=\"isSelectedEnd\">For three-phase systems:<\/p>\n<p class=\"isSelectedEnd\"><strong>kVA = \u221a3 \u00d7 Voltage \u00d7 Current \/ 1000<\/strong><\/p>\n<p class=\"isSelectedEnd\">If the BESS PCS has a rated active power of <strong>1000kW<\/strong> and operates close to unity power factor, the transformer capacity will generally need to be around 1000kVA or higher, depending on the actual system design.<\/p>\n<p class=\"isSelectedEnd\">However, selecting exactly the same kVA rating as the PCS is not always appropriate. Engineers should consider:<\/p>\n<ul data-spread=\"false\">\n<li>PCS maximum continuous power<\/li>\n<li>Charging and discharging requirements<\/li>\n<li>Power factor<\/li>\n<li>Transformer efficiency<\/li>\n<li>Ambient temperature<\/li>\n<li>Harmonic currents<\/li>\n<li>Continuous operating conditions<\/li>\n<li>Future system expansion<\/li>\n<\/ul>\n<p class=\"isSelectedEnd\">For industrial and commercial BESS projects, a suitable safety margin may also be considered to prevent continuous operation at the transformer&#8217;s maximum rated capacity.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"2_Match_the_Transformer_Voltage_to_the_PCS_and_Grid\"><\/span>2. Match the Transformer Voltage to the PCS and Grid<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p class=\"isSelectedEnd\">Voltage matching is one of the most important factors in BESS transformer selection.<\/p>\n<p class=\"isSelectedEnd\">For example, a system may use a PCS with a low-voltage AC output such as <strong>400V, 415V, 480V or 690V<\/strong>, while the facility or utility connection requires a medium-voltage output.<\/p>\n<p class=\"isSelectedEnd\">The transformer may therefore perform a step-up function such as:<\/p>\n<p class=\"isSelectedEnd\"><strong>400V \u2192 10kV<\/strong><\/p>\n<p class=\"isSelectedEnd\">or:<\/p>\n<p class=\"isSelectedEnd\"><strong>480V \u2192 13.8kV<\/strong><\/p>\n<p class=\"isSelectedEnd\">The actual voltage combination depends on the PCS, local electrical network and project requirements.<\/p>\n<p class=\"isSelectedEnd\">The transformer manufacturer should receive the exact <strong>primary voltage, secondary voltage, phase configuration and frequency<\/strong> before preparing the final design.<\/p>\n<p class=\"isSelectedEnd\">For international BESS projects, frequency is also important. Systems may require <strong>50 Hz atau 60 Hz<\/strong>, and the transformer must be designed accordingly.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"3_Consider_Dry_Type_vs_Oil-Immersed_Transformers\"><\/span>3. Consider Dry Type vs Oil-Immersed Transformers<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p class=\"isSelectedEnd\">Both dry type and oil-immersed transformers can be used in energy storage applications, depending on the installation and project requirements.<\/p>\n<p class=\"isSelectedEnd\"><a href=\"https:\/\/voltnexpower.com\/id\/pabrik-produsen-khusus-trafo-isolasi-tipe-kering-untuk-keperluan-industri\/\"><strong>Dry type transformers<\/strong><\/a> are often attractive for commercial and industrial BESS installations because they do not use liquid insulation and can be installed indoors or in equipment areas where fire and maintenance considerations are important.<\/p>\n<p class=\"isSelectedEnd\">Typical applications include:<\/p>\n<ul data-spread=\"false\">\n<li>Commercial BESS<\/li>\n<li>Industrial energy storage<\/li>\n<li>Solar + storage systems<\/li>\n<li>Microgrids<\/li>\n<li>Data centers<\/li>\n<li>Factory energy management systems<\/li>\n<li>Renewable energy projects<\/li>\n<\/ul>\n<p class=\"isSelectedEnd\">For larger outdoor utility-scale projects, oil-immersed transformers may also be considered because of their high capacity and cooling characteristics.<\/p>\n<p class=\"isSelectedEnd\">The choice should be based on capacity, installation location, fire protection requirements, environmental conditions, maintenance strategy and project specifications.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"4_Pay_Attention_to_PCS_Harmonics\"><\/span>4. Pay Attention to PCS Harmonics<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p class=\"isSelectedEnd\">A BESS transformer does not always operate with a simple linear load.<\/p>\n<p class=\"isSelectedEnd\">The <strong>Power Conversion System (PCS)<\/strong> uses power electronics to convert DC power from the battery into AC power. This switching process can introduce harmonic currents into the electrical system.<\/p>\n<p class=\"isSelectedEnd\">Therefore, transformer selection should consider the harmonic characteristics of the PCS.<\/p>\n<p class=\"isSelectedEnd\">Depending on the application, the project may require:<\/p>\n<ul data-spread=\"false\">\n<li>Low-loss transformer design<\/li>\n<li>Increased thermal capacity<\/li>\n<li>Appropriate winding configuration<\/li>\n<li>Harmonic-resistant design<\/li>\n<li>Suitable impedance<\/li>\n<li>Additional power quality equipment<\/li>\n<\/ul>\n<p class=\"isSelectedEnd\">The actual requirements should be confirmed from the PCS manufacturer&#8217;s technical documentation.<\/p>\n<p class=\"isSelectedEnd\">For larger systems, harmonic analysis and load calculations should be completed before final transformer sizing.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"5_Select_the_Correct_Transformer_Impedance\"><\/span>5. Select the Correct Transformer Impedance<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p class=\"isSelectedEnd\">Transformer impedance affects voltage regulation and short-circuit current.<\/p>\n<p class=\"isSelectedEnd\">For BESS applications, the transformer impedance should be coordinated with the PCS, switchgear and grid connection requirements.<\/p>\n<p class=\"isSelectedEnd\">A transformer with inappropriate impedance can affect system voltage characteristics and fault-current levels.<\/p>\n<p class=\"isSelectedEnd\">Typical transformer specifications may include an impedance value such as <strong>4%, 5%, 6% or a customized value<\/strong>, but the correct value depends on the complete electrical system.<\/p>\n<p class=\"isSelectedEnd\">Therefore, impedance should not be selected independently from the PCS and protection system.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"6_Consider_the_Installation_Environment\"><\/span>6. Consider the Installation Environment<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p class=\"isSelectedEnd\">BESS installations may be located inside factories, commercial buildings, outdoor containers, solar farms or dedicated energy storage stations.<\/p>\n<p class=\"isSelectedEnd\">Environmental conditions can significantly affect transformer selection.<\/p>\n<p class=\"isSelectedEnd\">Important factors include:<\/p>\n<ul data-spread=\"false\">\n<li>Ambient temperature<\/li>\n<li>Humidity<\/li>\n<li>Dust<\/li>\n<li>Salt exposure<\/li>\n<li>Altitude<\/li>\n<li>Indoor or outdoor installation<\/li>\n<li>Ventilation<\/li>\n<li>Enclosure protection<\/li>\n<li>Cooling requirements<\/li>\n<\/ul>\n<p class=\"isSelectedEnd\">For outdoor BESS projects, the transformer may require a weather-resistant enclosure and appropriate protection against environmental exposure.<\/p>\n<p class=\"isSelectedEnd\">For indoor installations, ventilation and heat dissipation should be considered to maintain reliable operation.<\/p>\n<p><span style=\"font-size: 130%;\"><a href=\"https:\/\/voltnexpower.com\/id\/rectifier-transformer-working-principle-types-applications-and-selection-guide\/\">Read More\uff1aRectifier Transformer: Working Principle, Types, Applications and Selection Guide<\/a><\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"7_Transformer_Configuration_for_Solar_BESS_Systems\"><\/span>7.
