Learn about transformer vector groups, configurations, and phase shifts in three-phase transformers for efficient power distribution systems.
What is vector group of transformer?
Transformers play an essential role in power distribution and transmission, and their configurations determine how they interact with the electrical system. One crucial aspect of transformers, particularly three-phase transformers, is the vector group —a classification that describes the phase difference between the primary and secondary windings, and how they are connected. This guide provides a deep dive into the fundamentals of transformer vector groups, their configurations, phase relationships, and practical implications. 1. Introduction to Transformer Operation Transformers are devices that transfer electrical energy between two or more circuits through electromagnetic induction. By applying an alternating current (AC) voltage to the primary winding, a current flows through the coil, creating a magnetic field around an iron core. This magnetic flux induces a voltage across the secondary coil, which is also wrapped around the core. 2. How Magnetic Flux and Coil Configurations Work The…
