Overview of Assessment
This course will be assessed through a range of practical exercises, assignments and progressive tests.
Assessment Tasks
Tests 70%:
Tow written assessments to demonstrate an understanding on single and three phase theory involving: AC Ssnusoidal alternating waveforms, phasors, complex numbers, Series and parallel AC circuits, polypahse systems, three phase generators, MEN systems, active, reactive, and apparent power, power factor correction, circuit protection and determination of conditions causing an existing circuit to be unsafe.
Practical exercises 15%
- Alteration of an existing circuit to comply with specified operating parameters.
- Development of AC circuits to comply with a specified function and operating parameters.
- Determination of causes of low power factor in an existing circuit.
When performing the practical exercises, students must demonstrate ability to:
o Organise and manage the tasks within the exercise requirements
o Cope with any contingencies that arise during the simulations and solve inherent problems
o Perform tasks autonomously and/or as a member of a team as task proscribes
o Perform task and manage work environment/equipment according to safe working practice and OH&S requirements.
