— General distribution schemes

There are no real specific technical standard references for the choice of the electricity distribution scheme, also in consideration of the fact that this choice is necessarily free and dependent on the process served. Electricity distribution systems are a fundamental infrastructure for most business processes and help to determine their performance in terms, for example, of energy management, safety, reliability and maintainability. If plant safety is an essential property as a legal requirement, reliability, availability and maintainability are instead characteristics of the plant that directly impact the business. The possible configurations that an electrical distribution system can assume can generally be traced back to three fundamental schemes:

• the simple radial scheme; • the double radial scheme; • the ring.

1 If short interruptions of service are acceptable in case of breakdowns or work on the system. 2 It is a function of the point where the ring is kept open.
