摘要： A method of operating a relay device, the method comprising the steps of: providing main circuit-breakers and a bus-tie-breaker connecting the main-circuit-breakers; defining a partial-differential-zone comprising a main circuit breaker and the bus-tie breaker; assigning a first value to the direction of the fault current flowing into the partial differential zone; - assigning a second value to the direction of the fault currents flowing out of the partial-differential- zone, wherein the first value is not equal to the second value; - comparing the values assigned to the fault currents; determining if the fault currents are flowing into the partial differential zone; and determining if at least two of the fault-currents is flowing in a different direction with respect to the partial-differential-zone wherein one of the fault currents is flowing into the partial-differential-zone and one of the fault currents is flowing out of the partial differential zone.

摘要： A circuit protection system (28) is provided in a circuit (10, 105) to protect power switches (14, 415, 420) from fault conditions using the protective algorithms (200). The algorithms (200) to control a response of said power switches to fault conditions to protect said circuit. The protective response of the power switches to a fault condition is displayed using the algorithms. The response enables the released energy from a fault condition to be minimized.
