Abstract: The upgrading and innovation of experimental teaching is crucial to the cultivation of new engineering talents. Aiming at the high risk factor and complex operation process of traditional high-voltage experiments, this article innovatively integrates VR technology into the teaching of high-voltage experiment courses. Taking the virtual experiment of high-voltage switchgear partial discharge multi-parameter testing and transformer winding deformation testing as examples, three-dimensional scene modeling and programming in Visual Studio are conducted to achieve the interactivity of the experiment, and a virtual experiment platform is established, Subsequently, a new high-voltage experimental teaching based on virtual reality technology was carried out. Practice has proven that interesting VR experimental methods can fully ensure experimental safety, improve the utilization rate of laboratory resources, mobilize students’ learning enthusiasm, and meet the engineering training requirements for the cultivation of high-voltage and insulation technology professionals in the new engineering background. During the COVID-19, the VR technology was successfully put into teaching, and the application effect was well reflected.
