GIS vs AIS - Substation Earthing· AEG GIS gas insulated switchgear up to 420 kV. Compressed SF6 gas used in MV and HV switchgears as an insulating medium has led to the development of compact gas-insulated substation (CIS) technology (figure 1). GIS, having many advantages over often used and conventional air-insulated substations (AIS), have been receiving wide application.Get Price
Substation Health Risks | EM Watch emit a low-frequency electromagnetic radiation (EMR) which creates an electromagnetic field (EMF). This EMF has two components, an electric field and a magnetic field. Don't worry too much about the electric field. It lacks power to penetrate the substation walls. But the magnetic field goes right through bricks, concrete, or a human body.Get Price
