Breaker and half bus scheme together with GIS meeting the need of single phase switching scheme require due diligence on various aspects. GIS layout implementing the breaker and half scheme configuration must consider the aspect i.e. operational & maintenance flexibility, Simple yet Compactness of layout, effective placement of module, least number of enclosure crossover, possibility of GIS extension and last but not least proper partitioning of gas tight sections in GIS. The balance consideration of above said aspects even though it is difficult to make choice among, will provide GIS solution which will save the interest of both manufacturer as well as end user.
