Modular and prefabricated GIS Product Platform

High levels of performance and reliability are required for such type of equipment. The last 50 years have shown incredible optimizations in the switchgear size through technology progress.

The latest improvement in the high-voltage substation design are not only related to pure technological improvement but probably more on the modularity and standardization of the equipment at different levels.

This paper investigates solutions to improve the modularity of a GIS to fit any layout in the most efficient and compact way. It relies on using a fixed dimension step and standard interfaces, allowing all combinations of housings in all 3 directions without adapters.

Then, the standardization of the GIS is studied, to show the benefits or harmonizing parts, assembly and architectures to reduce time for development, testing and industrialization. It results also in synergies in personal training and instructions, which is also interesting for the end users.

Finally, the quality aspects are discussed, and especially the processes that can be used to improve the quality of the delivered GIS. One of the key aspects to maintain a high quality is the standardization of parts and processes. The prefabrication and pre-test of GIS as transport units further minimizes the on-site work. All together is resulting in lower overall risk, associated costs and reduction of lead time
