Description / Abstract:
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 ÒactiveÓ 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 deÞned on a case-by-case
basis. However, if appropriate, more speciÞc guidelines will be
added in further revisions.
