  3. SafeLink CB Ring Distribution System Concept & Advantages In the event of fault in Underground Network, appropriate measures are required for quick fault location and isolation. Unlike Radial distribution system for system redundancy, Ring Topology of using RMU can still reduce downtime equally & still remain economical. Ring Main Units are deployed in a manner, that every load centre in the loop has an alternative source of supply available. In the event of fault, the faulty section can be isolated within minutes and supply to affected load centers can be resumed with alternative source. Detailed Simulation follows…… Load Centre RING SWITCH T-OFF SWITCH Back to Contents
