Explore the Effectiveness of Power Transformers for Secure Transmission, Distribution, and Utilization of Electrical Energy


Know More About  Power Transformers:

A transformer is a static electrical device that transfers energy by inductive coupling between its winding circuits. A varying current in the primary winding creates a varying magnetic flux in the transformer's core and thus a varying magnetic flux through the secondary winding. This varying magnetic flux induces a varying electromotive force (emf) or voltage in the secondary winding. Transformers are thus used to vary the relative voltage of circuits, which, in some cases, also isolates them. Transformers range in size from thumbnail-sized used in microphones to units weighing hundreds of tons interconnecting the power grid. A wide range of transformer designs are used in electronic and electric power applications.

Transformers are essential for the transmission, distribution, and utilization of electrical energy. ABB built one of the first power transformers in 1893 and remains market leader – in terms of market share, installed base and technological innovation – to this day. The transformer adjusts the voltage to a suitable level on each leg of power transmission from generation to the end user. This means stepping up the voltage at generation for long haul transmission with low losses and down to domestic voltage manageable in the power outlet for home and industry. ABB built its first three-phase-transformer for the very first commercial power transmission with alternating current (AC) in 1893. The transformer and the three-phase system were crucial innovations in power transmission and they made ABB a natural choice when Sweden and other European countries began to build their electricity and industrial infrastructures in the coming decades.
