  • Electrical protection arrangement for an electrical distribution network
    Publication number: 20100039741
    Abstract: Electrical distribution networks (9) are provided between an electrical power source (10, 42, 43, 50, 65) and electrical loads (11, 12, 13) in the form of a number of connections (A to G). Faults can occur within the electrical distribution network (9) resulting in fault electrical currents which may damage the network (9). An electrical protection arrangement comprises fault current flow detectors (A? to G?, AA, BB, AAA to DDD) in a hierarchy of levels defined by cascades of connections it is possible to utilise a controller to actively trip a circuit breaker associated with a respective fault current flow detector (A? to G?, AA, BB, AAA to DDD).
