ABSTRACT
An electrical transient is a temporary excess of voltage and/or current in an electrical circuit. Businesses are highly vulnerable to transients. This article describes the sources of transients and explains the need for transient voltage surge suppression (TVSS) devices. Points to consider in the selection of TVSS devices are listed, and comments are made on the costs of the effects of transients.
