Figure 2.1-27 Example of PSB element in Quad characteristic
Figure 2.1-28 shows the PSBS-out and PSBS-in logic. During a power swing, the
impedance viewed from the PSB elements passes through the area between the PSBSOUT and
PSBSIN in a certain time. In the event of a system fault, the impedance passes through this
area instantaneously. A power swing, therefore, can be detected in the time that the locus of
