Abstract:
1. A system for distribution of electric power between a transmission system and local consumers, the system comprising: a first chamber filled with an insulating medium; a second chamber filled with an insulating medium, wherein the first chamber and the second chamber are arranged adjacent to each other and the insulating medium in the first chamber is separated from the insulating medium in the second chamber; an intermediate wall separating the first chamber from the second chamber; a transformer arranged in the first chamber; a distribution unit arranged in the second chamber, said distribution unit being connected to the transformer and comprising connections for connection of the distribution system to the consumers, wherein the transformer and the distribution unit are integrated into a single module, the module comprising a first volume compensation device for equalizing the pressure between the insulating medium in the first chamber and the insulating medium in the second chamber, and a second volume compensation device for equalizing the pressure between the insulating medium in the second chamber and an ambient medium surrounding the module.
