Switching transients in electrical installations of buildings in Hong Kong

More and more sensitive electronic and computer-based devices or systems are connected to the electrical installations of buildings. Measures to ensure high power quality in the electricity supply network for the satisfactory operation of such equipment is a hot topic of research in electrical engineering. Electrical transients are one of the important issues in power quality. This paper presents the approach and ideas of a project at the University of Hong Kong which addresses this problem with particular emphasis on switching transients in typical electrical installations in Hong Kong buildings.
