4. Change the magnitude and angle of three phase voltages to achieve the impedances at
test points P1, P2,...., P28.
5. For test points P1 to P14, observe the operation value for the signal ZOUT and compare
the operation value with the set value.
6. For test points P15 to P28, observe the operation value for the signal ZIN and compare the
operation value with the set value.
Testing the power swing detection logic ZMRPSB
Preconditions
The following output signals shall be configured to binary outputs: ZOUT, measured
impedance within outer impedance boundary and ZIN, measured impedance within inner
impedance boundary and START, power swing detection.
1. Set
kLdRRv to values that are in accordance with the selectivity plan and the corresponding
operating characteristic is shown in Figure 40.
2. Set
3. Enable the input signal REL1PH to detect the power swing in one of the three phases.
4. The test points that are to be considered for the power swing detection are shown in
Figure 40.
