Summary of Intended Learning Outcomes
By the end of the course, the student should:
1. Appreciate the operation of the UK grid system, and be
aware of its main constituent components.
2. Understand the difference between real, reactive and
apparent power.
3. Be able to perform power factor correction calculations.
4. Be able to analyse balanced and unbalanced three phase
circuits.
5. Understand how a real transformer departs from the ideal,
and know what each component in the transformer equivalent
circuit represents.
6. Be able to perform basic transformer design calculations.
7. Be able to explain how a rotating magnetic field is produced
in the stator of a three phase ac machine.
8. Understand how a three phase ac machines operate.
Be able to perform basic calculations on ac machine operation
using the equivalent circuit.
9. Understand the operation of a dc motor, and be able to
perform calculations on its behaviour.
10. Understand how to wire to professional standards, and
safely test, a small motor control panel.
Assessment Information
100% written examination.
Any student who does not attend and perform satisfactorily on
the Power Engineering 2 laboratory is deemed to have failed
the course, as it tests competency regarding important safety
aspects of power engineering.
Special Arrangements
None
