Power Transformers
The Ideal Transformer
In single-phase two-winding transformers, two windings are wrapped around a magnetic core having a cross-sectional area A and magnetic permeability ...
Equivalent Circuits for Practical Transformers
Equivalent circuits of practical single-phase two-winding transformers differ from their ideal counterparts due to winding resistance and finite core ...
Three-Winding Transformers
Three identical single-phase transformers form a three-phase connection with high-voltage and low-voltage terminals configured across all four winding ...
Transformers with Off-Nominal Turns Ratios
Per-unit quantity models simplify transformer analysis compared to actual quantity models. Ideally, transformer winding is eliminated when voltage base ...
