They are used to\ntransfer electrical energy from one circuit to another, by electromagnetic\ninduction. Transformers are used to step-up or step-down the voltage level of\npower for transmission and distribution, and also for many other applications\nin industries. Transformer failures can lead to serious consequences, such as\npower outages, equipment damage, and even life-threatening situations.

href=\"https:\/\/swaritadvisors.com\/bis-certification\">Bureau of Indian Standards<\/a> (BIS) is a national standard-setting body in India, under the Ministry of Consumer Affairs, Food and Public Distribution. BIS has developed several standards for electrical transformers to ensure their quality and performance. These standards cover the design, manufacturing, testing, and operation of transformers, and also provide guidelines for their maintenance and safety. BIS standards for transformers include IS 2026, IS 1180, IS 2026-3, IS 11171, IS 1181, and many more.<\/p>\n\n\n\n<p>IS\n2026 is the primary standard for power transformers in India. It specifies the\ngeneral requirements for transformers, such as rating, insulation, cooling,\nnoise level, and many more. IS 1180 is another important standard that covers\nthe requirements for distribution transformers. IS 2026-3 provides guidelines\nfor testing of power transformers, including routine tests, type tests, and\nspecial tests. IS 11171 specifies the requirements for transformer oil, which\nis an essential component of transformers.<\/p>\n\n\n\n<p>BIS\nalso provides certification services for transformers, which ensure that the\ntransformers meet the relevant standards and are of good quality. BIS\ncertification is mandatory for certain types of transformers, such as power\ntransformers, distribution transformers, and furnace transformers.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Indian_Standards_Institution_ISI\"><\/span>Indian Standards Institution (ISI):<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Indian\nStandards Institution (ISI) is another national standard-setting body in India,\nwhich was established in 1947. ISI has developed several standards for\nelectrical transformers, which are similar to BIS standards. The major\ndifference between BIS and ISI standards is that ISI standards are applicable\nto products that are meant for export, while BIS standards are applicable to\nproducts that are meant for the Indian market.<\/p>\n\n\n\n<p>ISI\nstandards for transformers cover the same areas as BIS standards, such as\ndesign, manufacturing, testing, and operation. Some of the important ISI\nstandards for transformers include IS 2026, IS 1180, IS 2026-3, IS 11171, and\nmany more.
