This Graded Unit is designed to provide evidence that the candidate has achieved the following principal aims of the HNC/D awards in Electrical Engineering:
- develop knowledge, understanding and skills in a range of core electrical principles, electrical power systems, electrical machine principles and electrical safety at Higher National level (these studies in core electrical principles and technologies are underpinned by a mandatory Unit in Mathematics)
- develop candidates’ ability to apply analysis and synthesis skills to the solution of electrical engineering problems
- develop learning and transferable skills (including Core Skills)
- develop a range of Communication knowledge and skills relevant to the needs of electrical incorporated engineers
Recommended Prior Knowledge and Skills: It is recommended that the candidate should have completed or be in the process of completing the following Units relating to these specific aims prior to undertaking this Graded Unit:
- Single Phase A.C. Circuits
- Three Phase Systems
- Electricity Power Systems
- Electrical Machine Principles
- Mathematics for Engineering 1: Electronics and Electrical
It will consist of a written examination of three hours duration.
Note:
It should also be said that each of these HN modules are stand alone courses and are all achievements in their own merit. They are also often used for CPD (continuous professional development) to assist career progression.
If a student fails an end of unit test there is the opportunity for a resit at a later date. If a student falls short of a PASS by a few marks. The supportive exercises are then used as further evidence of the students work and the A-1 tutor can award a PASS in this instance based on academic judgement.
