Abstract—Physical experiment in engineering education is
necessary. But there are not enough teaching resources for
students to fully understand the experiment, because the physical
experimental equipment is expensive, bulky and scarce. Then
virtual experiment can be widely used in education. Taking the
experiment of the air gaps breakdown at AC high voltage for an
example, this paper represents the design of the virtual
experimental software. This software is used in the lab courses,
and the teaching effectiveness is very good according to the
feedbacks of students
