HVDC Transformers | Transformers | Siemens Energy Global transformers are used as coupling elements between AC grids and high-power rectifiers for very long overhead lines or submarine cables. Converting AC lines to DC can help increase the power transfer volume through existing rights of way and typically cuts line losses by 30-50%.
The Problem with Humidity in SF6 Gas-Insulated Systems hexafluoride is the gas most commonly used as insulator in power transmission and distribution switchgear. Water, however, can negatively affect the dielectric capabilities of SF 6 gas. To prevent operational and safety issues, it is important to measure and monitor humidity levels in gas-insulated switchgear (GIS).
