A transformer is a device used for transforming an AC voltage of one level into a voltage of another level with minimum power loss. Worldwide, transformers are used extensively in electricity supply systems, and many industrial consumers have voltage distribution networks running at high voltages that incorporate transformers.
This Unit has been designed to enable you to develop the knowledge and skills that will allow you to understand the theory and principles of these transformers.
You will begin by learning about the materials and designs used in the construction of transformers. You will then progress to study the operation of transformers. You will learn how to calculate quantities such as efficiency and voltage regulation. Both single phase and three phase transformers will be covered in this Unit. You will learn about the different winding configurations used in transformers, and the conditions required to be satisfied before individual transformers can safely be paralleled together. The operation and application of transformer fittings such as cooling systems and tap changers will be investigated, and the methods of protecting transformers against fault damage will be explained.
In summary, by the end of this Unit you should be able to: explain the construction characteristics of transformers; analyse the operation of single-phase transformers on load; analyse the operation of three phase transformers; and explain transformer protection.
The formal assessment for the Unit will take two forms: a laboratory exercise (or case study) and a written, two hour assessment paper. The laboratory exercise or case study will take place during the delivery of the Unit. The written assessment paper will be carried out at the end of the delivery of the Unit, and it will be conducted under closed book conditions. This means that you will not be allowed to take notes, textbooks etc. into the assessment. You will be allowed to use a scientific calculator.

“The first year went by fast as the class gelled together quickly and became a community that helped each other out, while having a laugh at the same time.”
“In my opinion, NESCol has one of the best reputations in the UK for providing engineering courses with second-to-none instructors.”
“I’m driven by feeling like I’m contributing to something important, and renewable energy is a growing and exciting sector to be involved in.”
“It’s a great industry to work in – there’s loads of pathways and opportunities. Engineering is about problem solving and teamwork and seeing how things work.”
“My time at NESCol, and the success I achieved, wouldn’t have been possible without the dedication and support of the teaching staff. I will always be grateful for the opportunity to fulfil my aspirations of further education, combined with the unique experience and the incredible peers I met along the way.”
“I am more of a hands on sort of guy so the apprenticeship route worked for me.”
“The best thing for your career is to have the qualifications to reflect the knowledge you have.”
“From juggling working full time, being at College and still having quality time with my daughter, it was challenging at times. Despite how hectic it was it made the experience even more worthwhile for me and the whole process was highly rewarding. “
This course requires some attendance at College, often for assessment purposes only. Please enquire about expectations for your specific course when booking.
Attendance is usually at the Aberdeen City Campus or Fraserburgh Campus.
When submitting your distance learning application form, please ensure you attach the additional information sheet listing qualifications and previous knowledge with your application. You may be required to attend College for assessment. Please check if this is a requirement for your course.
Distance Learning courses have flexible start dates and applications will be considered at all points of the year.
For non-Scottish residents – the College will confirm fees payable for your chosen course on booking and these may differ from the advertised fee.
