A ring topology is not considered fault tolerant. In a star topology, each device is normally connected to one central device and therefore is not fault tolerant.
In regions where large blocks of power are being transferred over double circuit EHV transmission lines, the occurrence of a &quot;cross country&quot; fault, could initiate serious system stability problems, if the fault is followed by a three-phase trip of both lines. For examle.
