摘要:
A device for sensing the position of a contact carrier (4) of a contact includes a housing (12), a sensor (66) supported by the housing (12) and a latch (36) that is movable by the contact carrier. The latch (36) has a latch member (40) located in proximity to the sensor (66) and that is generally non-reflective. The sensor (66) is configured to sense a presence or an absence of the latch member (40) at one particular location depending upon the position of the contact carrier (4). A method of sensing position of a contact carrier (4) of a contact module is also presented.

A system (30) for damping power system oscillation includes a damping device controller (100) for generating a damping control signal to compensate for a plurality of oscillation modes in the power system oscillations and a damping device (102) to generate a damping signal based on a damping control signal. The damping device controller (100) includes a plurality of outer closed loop paths each including an adaptive controller (108) configured to determine an individual oscillation mode from at least one power system measurement signal. Each adaptive controller is further configured to generate an adaptive control signal to shift at least one open loop pole of an inner loop path related to the individual oscillation mode to a closed loop location.
