Pertanto, acquistare il tipo giusto di trasformatore non riguarda il fatto che un preventivo sia il pi\u00f9 economico, ma il corrispondere le valutazioni del motore con le perdite, i livelli di tensione, il tipo di sistema di raffreddamento, cos\u00ec come i requisiti degli standard.<\/p>\n<p>La guida completa su come scegliere un trasformatore copre tutti i passaggi richiesti che ogni cliente deve seguire, nell'ordine in cui l'ingegnere li eseguir\u00e0.<\/p>\n<blockquote><p>In termini semplici, se desideri selezionare il tipo appropriato di trasformatore da acquistare, devi calcolare il carico massimo di cui avrai bisogno in kVA e poi scegliere la valutazione del trasformatore appropriata in modo che il carico di picco sia intorno a 60% a 80% della capacit\u00e0 del trasformatore. Inoltre, assicurati di bloccare il rapporto di tensione dei trasformatori, il gruppo vettoriale, l'impedenza, la classe di raffreddamento e il tipo di isolamento.

Non sommare la valutazione della targhetta di ogni singola macchina, altrimenti ti ritroverai con un trasformatore sovradimensionato. Invece, segui l'approccio professionale:<\/p>\n<table border=\"1\" cellspacing=\"0\" cellpadding=\"6\">\n<caption>Esempio di Calcolo della Dimensione del Trasformatore<\/caption>\n<tbody>\n<tr>\n<th>Passo<\/th>\n<th>Calcolo<\/th>\n<th>Risultato<\/th>\n<\/tr>\n<tr>\n<td>Carico connesso<\/td>\n<td>Somma di tutte le valutazioni delle attrezzature<\/td>\n<td>200 kVA<\/td>\n<\/tr>\n<tr>\n<td>Domanda massima<\/td>\n<td>Applicare il fattore di domanda 0,7<\/td>\n<td>840 kVA<\/td>\n<\/tr>\n<tr>\n<td>Correzione del fattore di potenza<\/td>\n<td>Compensare a 0,95<\/td>\n<td>884 kVA<\/td>\n<\/tr>\n<tr>\n<td>Margine di crescita<\/td>\n<td>Aggiungere 20%<\/td>\n<td>061 kVA<\/td>\n<\/tr>\n<tr>\n<td>Valutazione selezionata<\/td>\n<td>Dimensione standard pi\u00f9 vicina<\/td>\n<td>000 o 1.250 kVA<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>La regola d'oro stabilisce che la dimensione dell'unit\u00e0 dovrebbe essere tale che il carico di picco normale si trovi tra 60% e 80% della sua capacit\u00e0. Ad esempio, un'unit\u00e0 da 1000 kVA ha un carico di picco normale di 750 kVA, il che significherebbe che l'unit\u00e0 opera con un'efficienza ottimale con un certo margine di capacit\u00e0 per l'avviamento. Sovradimensionare un'unit\u00e0 comporta costi inutili e perdite inattive, mentre sottodimensionarla porta a un ciclo di vita rapido dell'unit\u00e0 e al rischio di guasti in caso di caldo.<\/p>\n<h2 id=\"step2\">Passo 2: Selezionare il Rapporto di Tensione e il Gruppo Vettoriale<\/h2>\n<p>Il rapporto di tensione deve corrispondere con le unit\u00e0 del generatore e del consumatore. In generale, per applicazioni industriali e commerciali, il primario del trasformatore di tensione \u00e8 intorno a 11 o 20 kV e il secondario 400\/230. Nei siti delle sottostazioni, i rapporti di tensione comuni sono 110\/20 kV, 33\/11 kV e 220 kV\/110 kV. Il gruppo vettoriale aiuta a determinare come sono collegate le fasi e se il trasformatore \u00e8 a terra o meno.<\/p>\n<table border=\"1\" cellspacing=\"0\" cellpadding=\"6\">\n<caption>Gruppi Vettoriali Comuni e Loro Utilizzi<\/caption>\n<tbody>\n<tr>\n<th>Gruppo Vettoriale<\/th>\n<th>Configurazione<\/th>\n<th>Applicazione Tipica<\/th>\n<\/tr>\n<tr>\n<td>Dyn11<\/td>\n<td>Primario delta, secondario stella con neutro<\/td>\n<td>Distribuzione, 11\/0,4 kV \u2014 il pi\u00f9 comune<\/td>\n<\/tr>\n<tr>\n<td>YNd11<\/td>\n<td>Stella primario con neutro, delta secondario<\/td>\n<td>Trasformatori di potenza per trasmissione e sotto-trasmissione<\/td>\n<\/tr>\n<tr>\n<td>Yyn0<\/td>\n<td>Stella-stella, entrambi i neutri<\/td>\n<td>Piccola distribuzione, reti specifiche<\/td>\n<\/tr>\n<tr>\n<td>YNyn0<\/td>\n<td>Stella-stella con entrambi i neutri<\/td>\n<td>Sistemi interconnessi con neutri a terra<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Quando si mettono in parallelo i trasformatori, \u00e8 necessario garantire la compatibilit\u00e0 con il gruppo vettoriale, l'impedenza e il rapporto. Un trasformatore Dyn11 non pu\u00f2 funzionare in tandem con YNd11. Quando non si \u00e8 certi, si pu\u00f2 richiedere un trasformatore Dyn11 per la propria distribuzione e si pu\u00f2 sempre verificare con il fornitore l'idoneit\u00e0 delle proprie configurazioni.<\/p>\n<h2 id=\"step3\">Passo 3: Scegliere Impedenza e Classe di Raffreddamento<\/h2>\n<p>Le caratteristiche della tensione di impedenza (che \u00e8 generalmente dal 4 percento al 6 percento per i trasformatori di distribuzione e tipicamente dall'8 percento al 12 percento per i trasformatori di potenza) definiscono la corrente di cortocircuito e la condivisione di potenza tra i sistemi paralleli. Bassa impedenza consente una corrente di guasto pi\u00f9 alta, ma ha una migliore regolazione della tensione; alta impedenza protegge le apparecchiature elettriche, ma porta a una scarsa regolazione della tensione. La maggior parte delle compagnie di servizi pubblici e dei progettisti industriali ha calcolato questo numero sulla base dell'analisi delle proprie reti; non assumere che la fabbrica lo conosca.<\/p>\n<p>La classe di raffreddamento indica quanto carico l'unit\u00e0 pu\u00f2 ospitare e a quale prezzo:<\/p>\n<table border=\"1\" cellspacing=\"0\" cellpadding=\"6\">\n<caption>Classi di Raffreddamento e Loro Applicazioni<\/caption>\n<tbody>\n<tr>\n<th>Codice di Raffreddamento<\/th>\n<th>Significato<\/th>\n<th>Quando Sceglierlo<\/th>\n<\/tr>\n<tr>\n<td>ONAN<\/td>\n<td>Olio naturale, aria naturale<\/td>\n<td>Distribuzione, semplice servizio all'aperto<\/td>\n<\/tr>\n<tr>\n<td>ONAN\/ONAF<\/td>\n<td>Adds forced-air fans<\/td>\n<td>Substation and industrial units with peak\/overload duty<\/td>\n<\/tr>\n<tr>\n<td>OFAF \/ ODAF<\/td>\n<td>Forced oil + air<\/td>\n<td>Large units above ~50 MVA<\/td>\n<\/tr>\n<tr>\n<td>Dry-type (AN\/AF)<\/td>\n<td>Air natural \/ forced<\/td>\n<td>Indoor, fire-sensitive installations<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>When the fans are activated, a transformer rated 20\/28 MVA ONAN\/ONAF provides 40% greater capacity, an economical approach to meet peak summer loads and other contingencies without purchasing a larger transformer.<\/p>\n<h2 id=\"step4\">Step 4: Oil-Immersed or Dry-Type?<\/h2>\n<p>This choice is driven mostly by location and fire codes:<\/p>\n<table border=\"1\" cellspacing=\"0\" cellpadding=\"6\">\n<caption>Oil-Immersed vs. Dry-Type Selection Guide<\/caption>\n<tbody>\n<tr>\n<th>Fattore<\/th>\n<th>Immerso nell'Olio<\/th>\n<th>Tipo Secco<\/th>\n<\/tr>\n<tr>\n<td>Best location<\/td>\n<td>Sottostazioni all'aperto<\/td>\n<td>Indoor, high-rise, marine<\/td>\n<\/tr>\n<tr>\n<td>Rating range<\/td>\n<td>50 kVA\u20131.200 MVA<\/td>\n<td>100 VA\u201340 MVA<\/td>\n<\/tr>\n<tr>\n<td>Relative cost (1 MVA)<\/td>\n<td>Base ($18k\u2013$45k)<\/td>\n<td>+40%\u201360% ($28k\u2013$70k)<\/td>\n<\/tr>\n<tr>\n<td>Rischio di incendio<\/td>\n<td>Oil containment needed<\/td>\n<td>Flame-retardant<\/td>\n<\/tr>\n<tr>\n<td>Manutenzione<\/td>\n<td>Oil testing, DGA<\/td>\n<td>Minimal, no oil<\/td>\n<\/tr>\n<tr>\n<td>Rumore<\/td>\n<td>Generally lower<\/td>\n<td>Higher for cast resin<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>If a transformer is outside or in an oil-filled substation, it must be oil-filled transformer.

If it is stable within \u00b15%, then a simple off-circuit switch with 2 or 3 positions (\u00b12.5%, \u00b15%) will work well. If daily fluctuations, peak and off-peak loads occur, the on-load switch (OLTC) should be used:<\/p>\n<ul>\n<li>Off-circuit switches can either be cheap (3-5 positions). However, they must de-energize the transformer to set the position, so they are used mainly on distribution transformers.<\/li>\n<li>OLTC can have various ratings from \u00b110% to \u00b116% with 13 to 17 iterations in automatic regulation mode, i.e it keeps the output voltage within \u00b12%; This is common for transmission or sub-transmission transformers.<\/li>\n<li>When you consider the cost of these systems, an OLTC presents an additional cost of about $15,000\u2013$60,000 based on the transformer rating; therefore you must treat it as an investment for quality of power.<\/li>\n<\/ul>\n<h2 id=\"step6\">Step 6: Evaluate Losses &amp; Efficiency<\/h2>\n<p>Make sure to make comparisons based on the total cost of ownership rather than only focusing on bid pricing. Transformers are in operation continuously which means losses are happening permanently. Request each supplier guaranteed values for both no-load and load losses so that you can complete a capitalized loss comparison:<\/p>\n<table border=\"1\" cellspacing=\"0\" cellpadding=\"6\">\n<caption>Loss Comparison Example (1,000 kVA, 11\/0.4 kV)<\/caption>\n<tbody>\n<tr>\n<th>Supplier<\/th>\n<th>Perdita a vuoto<\/th>\n<th>Perdita da carico<\/th>\n<th>Est.

This is why stringent energy consumption standards exist.<\/p>\n<h2 id=\"step7\">Step 7: Standards, Certification &amp; Testing<\/h2>\n<p>Your contract must mandate compliance with the IEC 60076-1 standard in general and with the specific IEC 60076 provisions relevant to your application and, additionally, the IEEE C57.12.00 standard for North America. Insist on receiving the following documents before payment:<\/p>\n<ul>\n<li>Type-Test Reports \u2013 for the temperature rise, lightning impulse, and short-circuit withstand tests conducted on a sample unit.<\/li>\n<li>Routine Test Certificates \u2013 for the ratio, impedance, losses, dielectric, and insulation resistance determined on your specific unit.<\/li>\n<li>Certifications \u2013 if necessary, CE mark, ISO 9001 quality certificate and IEC 60076-11 for dry-type transformers.<\/li>\n<li>Third-Party Inspection Report \u2013 usually by SGS or Bureau Veritas, or may be provided by your own expert supervising tests in the factory for relevant price orders.<\/li>\n<\/ul>\n<p>It is also advisable to abandon suppliers that refuse independent inspection or do not possess type-test reports irrespective of their pricing policy as certificates and records of examinations are the proof of the quality of a product.<\/p>\n<h2 id=\"step8\">Step 8: Compare Brands &amp; Prices<\/h2>\n<p>Both multinational companies and the Chinese industry adhere to IEC 60076 standards but differ in terms of price, lead time, and engineering services.

All the units are equipped with type test and routine test results, certification according to CE\/ISO standards, and their prices are much lower than those of their foreign competitors (the price difference varies between 30% and 50%). Also, the factory is open for OEM\/ODM projects and third-party inspections.<\/p>\n<p style=\"text-align: center;\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-10552\" src=\"https:\/\/subian-electric.com\/wp-content\/uploads\/2026\/08\/The-Complete-Selection-Checklist.webp\" alt=\"The Complete Selection Checklist\" width=\"1448\" height=\"1086\" \/><\/p>\n<h2 id=\"checklist\">The Complete Selection Checklist<\/h2>\n<ul>\n<li>Determine the peak load with the help of the demand factor and growth margin; ensure that the rating is chosen such that the peak load is between 60% and 80%. Verify the voltage values for supply and load and decide on both the ratio and vector group.<\/li>\n<li>The impedance must be acquired from the network study (5%-10% on average).<\/li>\n<li>Choose a cooling type: ONAN when working under standard loads, ONAN\/ONAF if overload is expected.<\/li>\n<li>Choose between oil and dry-type based on the place of installation and fire code requirements.<\/li>\n<li>Choose the tap changer: off-circuit if the supply voltage is stable, OLTC if more precise voltage stability is required.<\/li>\n<li>Compare offers based on guaranteed losses using a capitalized loss study for 20-30 years.<\/li>\n<li>Request the type test reports according to IEC 60076 and third-party inspection.<\/li>\n<li>Budget for 20%-40% of costs for protection, installation, testing, and construction works.<\/li>\n<li>Check the lead time, warranty (which usually lasts from 12 to 24 months), and service after the sale.<\/li>\n<\/ul>\n<h2 id=\"faq\">Domande frequenti<\/h2>\n<h3>How do I calculate the right transformer size for my building or factory?<\/h3>\n<p>Determine the connected load, multiply with demand factor of 0.6-0.85, correct power factor to 0.9-0.95, add anything from 15%-25% for growth to that. Then select the nearest standard rating so that the normal peak load is equal to somewhere between 60%-80% of the capacity. For example, if connected load equals 1200 kVA, demand factor is 0.7, and growth is 20%, the result will be something close to 1060 kVA. In this case, a unit with rating equal to either 1000 or 1250 kVA will do.<\/p>\n<h3>What is the difference between a 11\/0.4 kV and a 20\/0.4 kV transformer?<\/h3>\n<p>Both units have the same function but operate at different voltages in this instance, where the 11-kV unit is suitable for 11 kV incoming medium voltage lines and the 20-kV unit operates in 20 kV systems. While the kVA ratings can be the same, the high-voltage unit has higher BIL insulation as well as different construction, and in general costs slightly more.<\/p>\n<h3>Should I buy an oil-immersed or a dry-type transformer?<\/h3>\n<p>In some cases, dry-type transformers are used in occupied buildings and outdoor locations. The dry-type transformers are very high rated and maintenance free. The cost of dry-type transformer in range of $28000-$70000 and compared to oil immersed transformer in a range of $18000-$45000.<\/p>\n<h3>Why are transformers with the same rating priced so differently?<\/h3>\n<p>Loss guarantees, main steel quality, winding material (copper or aluminium), brand of tap changer, cooling class, history of type testing, and brand premium. Always do a capitalized-loss comparison: a unit that has low losses and costs an additional 5% to 10% is likely to save more in power costs during 20 years than its entire price difference.<\/p>\n<h3>What paperwork should I request before buying a transformer?<\/h3>\n<p>Ask for the type test report (temperature climbing, lightning impulse, short circuit), routine testing certification for your unit, ISO 9001 quality certification, CE marking if applicable, and the possibility of third party inspection. According to IEC 60076-1, ratio tolerance is \u00b10.5%, therefore verify the test results with your specification prior to accepting delivery.<\/p>\n<h2 id=\"references\">Riferimenti<\/h2>\n<ul>\n<li><a href=\"https:\/\/webstore.iec.ch\/en\/publication\/639\" rel=\"nofollow noopener\" target=\"_blank\">IEC 60076-1: Power Transformers \u2014 General<\/a> \u2014 The base standard for ratings, tolerances, and tests.<\/li>\n<li><a href=\"https:\/\/webstore.iec.ch\/en\/publication\/641\" rel=\"nofollow noopener\" target=\"_blank\">IEC 60076-7: Loading Guide for Oil-Immersed Power Transformers<\/a> \u2014 Overload capability and loading recommendations for sizing.<\/li>\n<li><a href=\"https:\/\/ieeexplore.ieee.org\/document\/5307241\" rel=\"nofollow noopener\" target=\"_blank\">IEEE C57.12.00: General Requirements for Liquid-Immersed Transformers<\/a> \u2014 North American selection and application standard.<\/li>\n<li><a href=\"https:\/\/www.energy.gov\/eere\/amo\/transformer-efficiency\" rel=\"nofollow noopener\" target=\"_blank\">US DOE: Transformer Efficiency Standards<\/a> \u2014 Efficiency regulations that shape loss specifications.<\/li>\n<li><a href=\"https:\/\/www.nfpa.org\/codes-and-standards\/nfpa-70-standard-development\" rel=\"nofollow noopener\" target=\"_blank\">NFPA 70: National Electrical Code<\/a> \u2014 Installation requirements for transformer selection and placement.<\/li>\n<li><a href=\"https:\/\/www.reinhausen.com\/en\" rel=\"nofollow noopener\" target=\"_blank\">Maschinenfabrik Reinhausen (MR)<\/a> \u2014 Reference for tap changer selection and voltage regulation.<\/li>\n<\/ul>\n<h2 id=\"conclusion\">Conclusione<\/h2>\n<p>The choice of the appropriate transformer is not simply one of price but consists of a process of eight specific engineering decisions.
