Abstract:
The present invention relates to a dielectric insulation medium comprising: a) sulphur hexafluoride (SF6) and/or tetrafluoro methane (CF4), in a mixture with b) at least one further component being an at least partially fluorinated fluoroketone.
Abstract:
The present invention relates to an offshore converter station (1) comprising at least one sealable room (4) containing amongst others a high voltage SF6 insulated converter installation. This sealed, but enterable room is filled with a non-toxic dielectric insulation gas containing next to dry air for example fluoroketone or hydrofluoro monoether. This allows for a smaller footprint of the offshore converter station.
Abstract:
A monitoring device (11-24, 211) for determining the concentration of a dielectric insulation fluid such as a perfluoroketones (PFK) in a room (4; 40-47) housing at least one high-voltage electrical apparatus (401A, 401B; 401, 411, 421, 431; 441, 451, 461, 471) and being accessible by humans essentially without modifying the room conditions, for example the room (4; 40-47) being a part of an air-insulated substation, with the monitoring system (11-24, 211) including one or more sensors (11, 21, 12, 22, 13, 23, 211) for determining an emission and/or absorption of the dielectric insulation fluid molecules (PFK) at at least one wavelength or wavelength band of the electromagnetic wave spectrum.
