Abstract

A case study of the structural design for a new generation of indoor electrical substation in South Africa is presented. New state-of-the-art switch gear has recently been developed in South Africa, which substantially reduces the cost but increases risk of explosive blast emanating from possible electrical faults in such indoor high voltage stations. The paper describes the concept of a suitable enclosing building structure and explains the analysis which is based on acoustic energy theory and accepted practice of blast resistant design.
