  • Electric distribution system protection
    Patent number: 9178350
    Abstract: A system for distributing electrical current to a plurality of loads includes a first sensor coupled to an input of a protection zone for measuring a first current entering the protection zone, wherein the protection zone includes at least a portion of an electrical distribution feeder. The system also includes a second sensor coupled to an output of the protection zone for measuring a second current exiting the protection zone, and a processor coupled to the first sensor and to the second sensor. The processor is programmed to receive measurements representative of the first current and the second current, and calculate a reactive current differential of the protection zone based on the first current and the second current. The processor is also programmed to compare the reactive current differential with a fault threshold, and generate an error notification if the reactive current differential is greater than the fault threshold.
