Large power transformers are designed to ensure high performance in a variety of applications and market segments, meeting the specific needs of power companies and of the industry in general What is the purpose of a large power transformer? The transformers with output above 50,000 kVA are responsible for adjusting the voltage among the different parts of the circuit in large power systems, enabling the power transmission in medium and long distances as economically as possible. Their most common application is in power utility companies, where they interconnect the power generation and transmission systems with the local distribution systems; however, they can also be used in large industry substations. Characteristics Designed according to the criteria established by NBR standard 5356 or complying with the specifications of the power utility company and/or specific requirements of each application; Usual outputs are quite varied (80, 100, 150, 200, 300, 400 and 500 MVA), including many specific characteristics when applied to systems with single-phase transformers, composing three-phase banks, and voltage classes up to 550 kV; Voltage regulation made by on-load tap changer (OLTC) and No-Load Tap Changer (NLTC); External coating for any aggressiveness level, with the choice of metallization of the tanks, producing additional strength for extremely severe environments;
