It provides candidates with the opportunity to:
On completion of the Unit the candidate should be able to:
1. Describe the production and characteristics of a three phase supply.
2. Analyse the response of balanced star and delta connected loads supplied by symmetrical three phase supplies.
3. Analyse the response of unbalanced star and delta connected loads supplied by 3- and 4-wire symmetrical three phase supplies.
4. Analyse power in three phase loads.
Credit points and level: 1 HN credit at SCQF level 7: (8 SCQF credit points at SCQF level 7)
For further information on this course please visit the SQA website.
You will begin by learning how three phase supplies are produced by generators. You will then progress to study the characteristics and responses of various types of loads that can be connected to three phase systems. Complex notation will be extensively used to calculate voltages and currents in a variety of three phase loads. You will also learn how to calculate the different types of power consumed by three phase loads. Methods of measuring active power in three phase systems will be studied in detail.
In summary, by the end of this Unit you should be able to: describe the production and characteristics of a three phase supply; use laws and theorems to analyse the response of various loads connected to a three phase supply system and describe techniques for measuring active power in such loads.
It is likely during the Unit that you will be provided with the opportunity to relate theory to practice by doing practical laboratory exercises and/or computer simulations.
Assessment
The formal assessment for this Unit will consist of a single assessment paper lasting two hours. The assessment will be conducted under closed-book conditions and you will not be allowed to take notes, textbooks, etc, into the assessment. However you will be allowed to use a scientific calculator. You will sit this assessment paper at the end of the delivery of the Unit.
Everything you need to know before applying to this course.
Candidates should possess a broad knowledge and understanding of single phase a.c. circuit theory. They should be able to solve single phase problems using network theorems and complex numbers. This may be evidenced by the possession of SQA Advanced Units HP46 47 DC and AC Principles, HP3J 47 Electrical Networks and Resonance and HP48 46 Engineering Mathematics 1.
