Abstract The gas insulated substations (GIS) are made up of a set of equipment submerged in SF6 gas and a metal enclosure in which all the equipment associated with the substation is located. The GIS are being widely used in the high voltage electrical sector, due to this, developments and a high degree of research corresponding to new trends or emerging technologies that allow advances in this equipment are being presented. for this reason, this report contains a documentary investigation on the subject of isolated gas substations, through which a bibliometric analysis was carried out that allowed observing the high interest that GIS present in the scientific community in different parts of the planet. The objective of this work is to provide information corresponding to GIS such as some technical characteristics, a regulatory framework and new emerging technologies.
