Substation Transformer


Power Transformer: A power transformer is an electrical device consisting of one coil of wire placed in close proximity to one or more other coils, used to couple two or more alternating-current (AC) circuits together by employing the induction between the coils. The coil connected to the power source is called the primary coil, and the other coils are known as secondaries. A power transformer in which the secondary voltage is higher than the primary is called a step-up power transformer.
