SF6 gas has virtually replaced oil and air as the dielectric insulator in medium (MV) and high (HV) circuit breakers, switchgear, gas-insulated substations and electrical equipment. Despite SF6 being an inert gas during normal use, when electrical discharges occur through the operation of high voltage equipment insulated with SF6, highly toxic

The Gas Insulated Substation (GIS) is a compact assembly consisting of multiple components enclosed in a metallic covering with compressed sulphur hexafluoride (SF6) gas as an insulating medium. The concept of the gas insulated substation was introduced in 1920 when oil was used as the insulating medium in the system.

Online Dissolved Gas in oil monitoring of multiple gases will provide for rapid detection and diagnosis of many faults; The universal fault gas is Hydrogen, produced under all fault temperatures and conditions. For more information on Dissolved Gas Analysis products or solutions, contact us.

Project involves the construction a new indoor 380kV Gas Insulated Substation, named as Sudair Solar PV 380kV Substation. It includes protection, control, communication and SAS/SCADA systems. The Substation consist of following major equipment:

Siemens Transmission Products offers all products of high-voltage substations including bundling and their electrical integration to systems up to 1.200kV: Tranformers, gas-insulated switchgears, circuit breakers, surge arresters, disconnectors, instrument transformers, and bushings.

Jan 24, 2017Gas Insulated Switchgear (GIS) has been widely used in substations. The insulating medium used in GIS is sulfur hexafluoride (SF6) gas. However, the internal insulation defect existed in GIS would inevitably lead to partial discharge (PD), and cause the composition of SF6 to SOF2, SO2F2 and SO2 and other characteristic component gases.

SF6 Gas-Insulated transfomers are designed to reduce fire hazards and less risk on the environment. By directly coupling with gas-insulated Switchgear, substation space can be minimized as the result of compact facilities a non -flammable, non-polluting and Tank-explosion Prevention Transformer.

Dec 04, 2017Gas-insulated switchgear (GIS) is a common electrical equipment, which uses sulfur hexafluoride (SF6) as insulating medium instead of traditional air. It has good reliability and flexibility. However, GIS may have internal defects and partial discharge (PD) is then induced. PD will cause great harm to GIS and power system. Therefore, it is of great importance to study the intrinsic

In 1973, it installed the first 500kV hybrid gas-insulated substation. Three years later, Mitsubishi Electric constructed the world’s first 550kV fully gas insulated switchyard at the Ohi Nuclear Power Station, which is the largest nuclear power plant in Japan. Since then, more than 20,000 GIS bays have been installed in substations worldwide.
