Can a ring network be protected by relays

Can a ring network be protected by relays

In the ring distribution network, differential relays, which rely on communication between the protection relays, are used for the underground cable protection. To guarantee cable protection when communication is failed, an auxiliary protection by using directional overcurrent. This article introduces a new approach for validating directional overcurrent protection schemes in ring-topology electrical distribution systems with distributed energy resources (DERs). It is not generally possible to operate a system as a closed ring using overcurrent standard grading methods while achieving discrimination and maintaining reasonable. The ring main switch enables the underground cable system to be isolated in sections, and the interconnection of adjacent feeders. [pdf]
