Bibliometric review of emerging technologies in Gas Insulated Substations SF6

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.

Digital colorimetric sensing for real‐time gas monitoring for smart green energy system

“…Based on the above description and measurements, color‐variable CSF can detect SO 2 selectively. However, the direct application of CSF is limited because the GIS uses a closed structure to maintain the high pressure of SF 6 , making routine inspections difficult 13 . Therefore, a digital real‐time monitoring platform with CSF was designed to detect SO 2 gas in GIS with extremely high precision.…”

“…12 Compared to insulating oil and solid insulators, GIS has superior insulation performance, a low dielectric constant, and quick insulation recovery ability, making it an excellent choice for small-scale substations in dense buildings. 13 Additionally, all charging components for power supply and distribution are integrated within the GIS and gas-sealed, ensuring high reliability and simplifying the maintenance process. 14 Because of its compact footprint, excellent security, and ease of maintenance, GIS is crucial for controlling, protecting, and isolating electrical equipment during power operation and distribution.…”

Trends in Measuring Instrument Transformers for Gas-Insulated Switchgears: A Review

“…ITs for gas-insulated switchgears (GISs) consist of voltage transformers (VTs) and a current transformer (CT), and transformer designs suitable for GISs have been employed to measure voltage and current in power systems since 1966 [3,4]. Unlike air-insulated switchgears (AISs), GISs use sulfur hexafluoride (SF 6 ) as an insulating gas, allowing higher insulation performance and compact design.…”
