(Offered in odd years only.)
Transformers are an essential component in any electrical system. Correct specification, installation and maintenance determine the viability of the system in which the transformers are installed. This course explores the construction, operation and maintenance of power transformers, including the best practice of condition monitoring techniques.

This course focuses on key aspects to consider throughout the transformer lifecycle. It is delivered through a combination of lectures and lab sessions. To enhance students' understanding of practical issues, several industry experts also share their experiences during lectures. Lab sessions are designed to provide hands-on training in condition monitoring measurements for transformers. Students will have the opportunity to visit the Transformer Innovation Centre lab, where they can explore online monitoring systems used in real transformers. As sustainable operation becomes increasingly important for the power industry, the course also offers insights into the use of biodegradable materials in transformers to reduce environmental impact.

Course requirements

Assumed background

Students are required to have general understanding of transformerᅠprinciples, equivalent circuits and operation.

  2. Understand general operational issues associated with transformers.
  3. Explain the different types of failure mode for power transformers.
  4. Identify the different condition monitoring techniques available for transformers.
  5. Analyse test data from power transformers to determine if operation is normal, or if a fault is suspected.
  6. Understand main considerations for maintaining vegetable oil filled transformers.

Task description

In this course 3 laboratory demonstrations on condition monitoring of transformers will be performed. After attending all labs students should submit a reflection report covering the content covered in the laboratory demonstrations. All students must go through the laboratory induction and risk assessments before attending the lab sessions and are required to follow the set safety guidelines such as wearing covered shoes, tied back or confined long hair, wearing suitable clothes that are not easily tangled with lab equipment. 

More information about the laboratory activities, Safety requirements and report structure will be available in Blackboard.

After each lab session a question and answer session will be conducted to provide feedback on student understanding about the conducted laboratory demonstration.

This assessment task evaluates students' abilities, skills and knowledge without the aid of generative Artificial Intelligence (AI) or Machine Translation (MT). Students are advised that the use of AI or MT technologies to develop responses is strictly prohibited and may constitute student misconduct under the Student Code of Conduct.
