A more practical approach to integrate low voltage distribution system into the electrical engineering curriculum

Abstract

This paper describes the author's new attempt to introduce a 10-hour lecture on low voltage (LV) distribution system with a 5-hour design exercise and a 5-hour project work for all electrical engineering students. It is felt that most of the electrical engineering graduates will possibly encounter more applications in the LV system rather than the traditional power system analysis. The system earthing and the associated electrical parts for the LV network can be easily implemented in a laboratory for students to test and operate. In the design exercise, the PC-based integrated tool not only guides the students in a step-by-step approach and provides a CAD tool to automate the repetitive design process, it also evaluates the student's performance in the design exercise by using error log and a demerit point system. In the guided project work, the students are exposed to a physical LV simulator identical to an industrial installation to carry out inspection, testing, turn-on supply, fault diagnosis and restoration of supply. In a survey from 600 students, 24% strongly agreed, and 52% agreed that this 10-hour design and project works are useful and challenging. Many students expressed that they are interested in their first exposure to a power engineering project.
