GROUPED ELEMENTS
5
The power swing detect element provides both power swing blocking and out-of-step tripping functions. The element
measures the positive-sequence apparent impedance and traces its locus with respect to either two or three user-
selectable operating characteristic boundaries. Upon detecting appropriate timing relations, the blocking and/or tripping
indications are given through FlexLogic operands. The element incorporates an adaptive disturbance detector. This
