Course description and aims

This course focuses on the high-voltage technology used in electric power apparatuses and electric machinery. The gas breakdown, discharge initiation, electric conduction and breakdown of liquid/solid/composite materials are shown. The generation of DC, AC, pulsed high-voltage and large current, measurement techniques, and surge voltage propagation and protection will be explained. The topics include electric power equipment (bushings, cables, switchgears, and arresters), high-voltage and large-current test equipment, accelerators, electric precipitators, ozone generators, and other applications.

Student learning outcomes

By the end of this course, students will be able to: 1) understand the basic theory of high-voltage engineering, 2) explain the operating principles of high-voltage and large-power apparatuses or other electric machinery, 3) understand measurement and evaluation methods for high voltage or large current, and 4) compute the basic breakdown phenomena with MATLAB® and analyze the transient circuit phenomena in high-voltage and large-power apparatuses using LTspice®.

Corresponding educational goals are:
(1) Specialist skills Fundamental specialist skills
(4) Applied skills (inquisitive thinking and/or problem-finding skills) Organization and analysis
(7) Skills acquiring a wide range of expertise, and expanding it into more advanced and other specialized areas


high voltage, large current, insulator, dielectric breakdown, sparking voltage, impulse voltage, voltage divider, bushing, gas-insulated switchgear, arrester, electric precipitator, ozone generator.

Competencies that will be developed

Specialist skills Intercultural skills Communication skills Critical thinking skills Practical and/or problem-solving skills

Class flow

The class proceeds with the course text book. A high-voltage lab tour, numerical simulations of transient circuits, and exercise problems related to the lecture will be provided. A summary of the topics and learning outcomes of each class will also be given. Handbook® is used for preparation, review purposes, and active learning.
