Section 11
Testing functionality by secondary injection
Testing the power swing detection logic ZMRPSB (68)
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 PICKUP, 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 38.
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
38.

5. Inject voltage in one of the three phases in accordance with the test point P1 by keeping
constant current in three phases throughout testing and maintaining rated voltage for other
two phases.
