How does impedance affect Transformer size?


Impedance in transformers is primarily related to the resistance and reactance of the windings.

A higher impedance typically results in a larger transformer size.

This is because a higher impedance requires more turns in the winding to achieve the desired voltage transformation, leading to increased copper losses and a larger core size. Additionally, higher impedance transformers may have larger insulation requirements.

Overall, impedance influences the design and size of a transformer, with higher impedance generally contributing to larger dimensions.
