Learning Outcomes
1.Communicate an understanding of the basic principles of electromagnetics, electrical power systems and electrical machines.
2.Define and apply reluctance models to analyse the electrical performance of magnetic components in terms of their structure and magnetic properties; in particular, to determine inductance values and levels of magnetic flux density under different conditions.
3.Apply measurement test results to produce an equivalent circuit model of a transformer.
4.Using an equivalent circuit model, analyse the response of a transformer under different load conditions in terms of such quantities as power, efficiency and regulation.
5.Apply equivalent circuit models to predict and analyse the performance of DC motors under different conditions.
6.Apply 3-phase and per unit systems to calculate different system parameters; e.g. line & phase voltages, currents & impedance.
7.Determine and analyse the response of a 3-phase induction motor.
