Teaching and learning methods

This course is delivered through face to face lectures that involve problem classes during the sessions. Additional material including films and worksheets are provided in the virtual learning environment. Students are encouraged to ask questions during the classes and use is made of sli.do to capture these.

The course also involves demonstrations within the high voltage laboratories where students see practical testing being carried out on power system equipment.
