A fault protection system whose trip logic considers power magnitude and direction at first and second points on a conductor is provided. Under normal operating conditions, power flows in the same direction through first and second points on the conductor. Under faulted conditions, a differential power condition exists; that is, the power flowing at a first point on the conductor is of different magnitude and/or direction than the power flowing at a second point on the conductor. The trip logic identifies the differential power condition as the result of a fault between the first and second points on the conductor and causes a protective device on each side of the fault to trip open, thus isolating the fault.
