IEEE C37.100.7-2023

The guide reviews existing standards and performance criteria for switchgear rated above 1000 V. Each aspect of performance is discussed within the context of sulfur hexafluoride alternatives, how their behavior may differ from existing technologies, and how this behavior may lead to changes in the qualification process. Relevant analytical, numerical, and test methods are discussed which may contribute to the process of performance evaluation and evolution of the standards.

The purpose of this guide is to review the performance characteristics of current Sulfur Hexafluoride alternatives in gas insulated equipment (GIE) and compare these with the demands encountered in service. The guide reveals the reasoning behind existing standard requirements and presents information relevant to their adequacy for SF-alternatives.

New IEEE Standard - Active. Existing standards and performance criteria for switchgear rated above 1000 V are reviewed in this guide. Each aspect of performance is discussed within the context of Sulfur Hexafluoride alternatives, how their behavior might differ from existing technologies and how this behavior can lead to changes in the qualification process. Relevant analytical, numerical and test methods are discussed which contribute to the process of performance evaluation and future evolution of the standards.
