    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 system and method according to various embodiments can include a universal contact input status detection circuit. A voltage source wets a contact with a wetting voltage. A current mirror circuit is connected across an input of the contact to provide a constant wetting current over a wide input voltage range. The input voltage can be varied over a range wide enough to include both AC voltages and DC voltages. The current mirror circuit maintains the constant wetting current during varying wetting voltage inputs across the input of the contact. A wetting voltage sensor senses the wetting voltage provided to the contact so that the status of the contact can be determined.

The nut engaging assembly includes: a nut engaging element (102,130) to engage the nut in the recess, at least one stackable riser element (132) to stackably connect to one of the nut engaging element and an adjacent stackable riser element (132,132C,132D,132F) therebelow, and a transmission engaging element (104,140) to stackably connect to an uppermost one of the at least one stackable riser element. A ratchet interface (104,106,130) within the nut engaging assembly allows rotation of the nut engaging element in only one direction, while other stackable elements rotationally interlock. A low profile transmission extends within a small space to transmit rotational power (108) to the nut engaging assembly. The nut torqueing device is applicable with a terminal nut of an electric generator.
