  • The history of gas-insulated substations | Think Grid

    Moving HV substations closer to consumers results in reduced transmission losses. Indoor GIS reduce the environmental influences on the switchgear, reducing maintenance needs and increasing lifetime. More and more “intelligence” is integrated into the GIS using electronic devices, forming part of digital substations.
