Conclusions
Compact Substations using Mixed Technology Switchgear (MTS) is not a new
concept.
MTS shows clear advantages in less space required for the same SLD, extended
SLD in the same space, higher flexibility of layout, easier engineering and
integration with the secondary systems and reduced maintenance efforts and
costs
There are different applications for AIS, GIS and MTS.
Cigre Working Group B3–20 is compiling a brochure evaluating the different
technologies giving users guidelines in their application.
IEC 62271–205 on compact switchgear assemblies has been developed to cater
for the new arrangement possibilities that have been developed by
manufacturers and to ensure that the complete switchgear assemblies are
covered by a single standard.
