Abstract: Information of special relevance to planning, design, testing, installation, operation and maintenance of gas-insulated substations (GIS) and equipment is provided in this guide, which is intended to supplement IEEE Std C37.122. This guide is applicable to all gas-insulated substations (GIS) above 52 kV. However, the importance of topics covered varies with application category. For example, the issues related to advanced field test techniques and very fast transients (VFT) are of particular interest for extrahigh voltage (EHV) gas-insulated substations (GIS). Keywords: gas-insulated metal enclosed switchgear, gas-insulated substation, gas-insulated switchgear, GIS, GIS design, GIS equipment, GIS installation, GIS testing, IEEE C37.122, SF6, sulfur hexafluoride, VFT, very fast transient, partial discharge, PD.
