ABSTRACT:
A network protector relay having trip characteristics which respond not only to the direction of the flow of positive-sequence power through the breaker outwardly of the network but which will respond to unbalanced and simultaneous faults in the feeder network as well. The network protector relay in addition to its tripping characteristics includes closing characteristics which will permit the automatic closing of a breaker only when the phase sequence of the feeder is the same as that of the network, there is a proper phase relationship between the network and feeder and the magnitude of the feeder voltage is such that power flow will be in a direction toward the network.
