— Scheme

— Ring scheme

This scheme connects the various user nodes in a ring, for each of which two alternative supply routes are available. The ring scheme is a compromise between the previous schemes and as such has the following advantages and disadvantages: • failure of one element of the supply causes the total outage of the plant, while downstream failures can be managed to keep the remaining part of the plant live; • flexibility, cost of materials and installation are lower than those of the double radial scheme, but higher than those of the simple radial scheme.
