Transformers

Change voltage levels, isolate systems and understand the machine at the heart of every grid.

CHAPTER CONTENT

Choose a subchapter.

Every subject opens on its own focused page, with no unrelated lesson content around it.

Mutual induction and the physical principle behind voltage conversion.

Cores, windings, cooling and the machines used in real networks.

Connect turns ratio to voltage and current transformation.

Decode winding connections, phase displacement and Dyn notation.

Model losses, magnetisation and leakage impedance.

Separate copper and iron losses and evaluate performance.

Change transformer ratings and watch prospective short-circuit current react.
