Development of a Virtual Experiment System for Transformer Characteristics Experiments in Student Laboratory

We have developed a virtual laboratory for student laboratory on transformer characteristics. In the past, the division of roles was fixed during student laboratory in our department. Many students felt that they could not wire even if they looked at the circuit diagram. Therefore, we developed a virtual laboratory where students can input wiring data while looking at a circuit diagram on the Web and automatically determine whether the wiring is correct or incorrect. In addition, a video on transformer experiments was also created on the Web. In fact, third-year students in this department were asked to use the virtual laboratory, and a questionnaire survey was conducted. As a result, it was found that the virtual experiment developed in this study is effective for learning because the students can see the circuit diagram and practice wiring as many times as they want until. The virtual experiment data can be displayed after the wiring is completed, which is considered to have improved the educational effect.
