13 Gas compartments
Function The distribution of the gas compartments is decisive for working on the switchgear during
operation and the resulting operational restrictions. Thus, in case of fault, the distribution of
the gas compartments determines the extent of work.
The following example shows the distribution of the gas compartments in a switchgear with
double busbar system with the associated item designations of the manometers. For more
detailed data to other configurations, please contact your regional Siemens representative.
