Introduction to Substation Transformer
A substation transformer is a crucial component in the electrical power system. It plays a vital role in stepping up or stepping down the voltage levels to facilitate the efficient transmission and distribution of electricity. Substation transformers are used in various substations, including transmission substations, distribution substations, and industrial substations. They help in reducing power losses during long – distance transmission by increasing the voltage at the generating end and then reducing it to a suitable level for end – users at the distribution end. These transformers are designed to handle large amounts of electrical power and are built with high – quality materials and advanced technologies to ensure reliable and safe operation.
