A gas-insulated switchgear device for high- and medium-voltage applications, comprising an enclosure which contains a disconnection unit which is electrically connected to a first electric terminal and is arranged in the enclosure in a substantially central position, and a first interruption unit and a second interruption unit which can be connected electrically to the disconnection unit and, respectively, to a second electric terminal and a third electric terminal, the first and second interruption units being arranged mutually opposite with respect to the disconnection unit.

Reliability assessment of a power system having an integrated component is provided by retrieving individual component failure rates associated with individual components of the integrated component. A failure time is modeled based on the individual component failure rates associated with individual components of the integrated component. Individual component maintenance times are retrieved associated with individual components of the integrated component. A maintenance time is modeled based on the individual component maintenance times associated with individual components of the integrated component. A reliability assessment is determined based on the interconnectivity of components of the power system, the modeled maintenance times, and the modeled failure times.
