Electrical Machines and Transformers

Instruction is in the form of lectures, exercises and mandatory laboratory sessions.
Magnetic circuits: important properties in non-linear magnetic materials, calculations of magnetic circuits, magnetizing losses and magnetizing current.
Transformers: step down and step up transformers, law of induction, transformer theorem, open circuit, voltage drop, equivalent scheme, loss, efficiency, structure, materials, coiling, cooling, three-phase connection, rated current data in switching, transformer testing, short curcuit impedance, winding connector, parallel connection of three-phase transformers.
Direct current machines: construction, theory, separate-, shunt-, and series magnetization, armature reaction, commutation, loss, efficiency, start, brake, speed rotation control.
Asynchronous machines: construction, theory, short circuit- and slip-ring machine, loss, efficiency, start, brake, speed rotation control, single phase operation, generator operation.
Synchronous machines: construction, theory, generator and machine operation, over- and under-magnetising, start, phase synkronization, loss, efficiency.
