Reclosers are programmed to automate the reset process and allow a more granular approach to service restoration. The result is increased availability of supply.
Reclosers address this problem by further dividing up the network into smaller sections. For instance, the city grid example above might be equipped with reclosers at every branch point on the network. Reclosers, because of their upstream position in the network, handle much less power than the breakers at the feeder stations, and therefore can be set to trip at much lower power levels. This means that a single event on the grid will cut off only the section handled by a single recloser, long before the feeder station would notice a problem.

S, theoretically, if a person was interested in sabotaging a large transformer one would first want to disable the reclosers upstream? Asking for a friend.
