Switching Transients Analysis Fundamentals

Velimir Lackovic, MScEE.

Switching transients severe enough to cause problems in industrial power systems are most often associated with inadequate or malfunctioning breakers or switches and the switching of capacitor banks and other frequently switched loads. The arc furnace system is most frequently studied because of its high frequency of switching and the related use of capacitor banks.

By properly using digital computer programs these problems can be detected early in the design stage. In addition to these types of switching transient problems, digital computer programs can be used to analyse other system anomalies such as lightning arrester operation.

This course begins with a discussion of the switching transient phenomena, describes root causes and explains system operation is affected. A detailed explanation of modelling and calculation procedure is offered. Selection and sizing of surge arrester is covered in details. Explained techniques can be implemented in any commercial power system software package.

This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
