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) analyze the transient circuit phenomena in high-voltage and large-power apparatuses using LTspice®.
