Star/Delta Three Phase System: Educational Trainer

Abstract

The 3-Phase Star/Delta connection system is a method used for connection purposes for a 3-phase electrical system. The use of trainers for the 3-phase system is widely used in educational institutions as one of the applicable learning method to meet the requirements of the syllabus that has been prepared in accordance with the requirements of accreditation certification recognition for each program offered in the institution. Comparison study between existing trainers in the market found out few elements that need to be improve to fulfil the objective of syllabus in polytechnic and suitable for use in teaching and learning (TnL) sessions. These Three Phase Star/Delta System Learning Trainer capable to introduces students to the basic methods of Star/Delta connections by combining teaching methods that require higher level thinking. This trainer has been equipped with multimeter and load connection terminals that can be tested by students. This trainer has been built to be flexible to use either by using a 3-phase supply or a 1-phase supply socket. So that students can still practice the 3-phase connection method according to the objective target in the lecturer's TnL session despite the constraints of the 3-phase supply facility. The use of a 3-phase trainer produces results that are different from the existing trainers and this is able to increase the level of understanding of the students which in turn helps the lecturer during the TnL session.
