Safe. Link 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…… RING SWITCH Load Centre Back to Contents T-OFF SWITCH
