Claim Text:
1. A device for interrupting a flow of electrical power in an electrical distribution system having a radial circuit with at least one circuit interrupting device, the radial circuit being coupled to an adjacent circuit by an open switch, the at least one circuit interrupting device having a reclose time, the device comprising: a sensor operably coupled to the radial circuit, the sensor configured to generate a signal in the event of loss of system power, the loss of system power includes substantially no voltage and current measured by the sensor; a switching mechanism coupled to the electrical distribution system, the switching mechanism movable between an open position and a closed position; a controller operably coupled to the sensor and the switching mechanism, the controller having a processor that is responsive to executable computer instructions when executed on the processor for initiating a timer in response to the signal and determining a measured reclose time with the timer; and wherein the processor is further responsive to executable computer instructions for actuating the switching mechanism in response to the measured reclose time is substantially equal to the reclose time of the at least one circuit interrupting device; wherein the controller further includes a first logic circuit and a second logic circuit, the first logic circuit determines when an upstream tripping device is opening and closing based at least in part on the timer, the upstream tripping device configured to open when an overcurrent condition is present, and the second logic circuit determines when a location of a fault is upstream or downstream from the device.
