C37.122.1-2014 - IEEE Approved Draft Guide for Gas-Insulated Substations Rated Above 52 kV

Description: This guide provides information of special relevance to the planning, design, testing, installation, operation and maintenance of gas-insulated substations(GIS) and equipment. This guide is intended to supplement IEEE Std C37-122-1993(R2002). 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 extra high voltage (EHV) gas-insulated substations (GIS).
