Scope
These recommendations apply to the following cases: a) When a gas-insulated substation (GIS) has to be connected to another GIS@ in the case of a planned or unplanned extension. b) When@ in the same way@ a GIS has to be connected to a gas-insulated transmission line (GIL) of another make. In both cases@ the interface is assumed to concern busbars or busducts only@ and not direct connections to ?active? devices such as circuit breakers or disconnectors. The case of a three-phase GIS or GIL can be more complicated than the single-phase case@ and should be de?ned on a case-by-case basis. However@ if appropriate@ more speci?c guidelines will be added in further revisions.
