Summary① Electrical Power System → Electrical Power System is discussed taking account
of reliability , efficiency, and cost. → Electrical equipment layout were discussed to
determine the cavern size of substations.
33
SummaryAsia region electrical design
② Electrical Grounding System → A grounding system for a hard-rock mountain site
was discussed.
③ Communication Network System → Unified and extended network system was proposed
taking advantage of sufficiently radiation-shielded “Kamaboko-type” service tunnel.
