Testing the operating characteristics
Preconditions
The following output signals shall be configured to binary output available:
impedance within outer impedance boundary and
impedance boundary.
1. Set
kLdRRv to values that are in accordance with the selectivity plan and the corresponding
operating characteristic is as shown in Figure 39.
2. Set
3. The test points that are to be considered for the measurement accuracy of set resistive
and reactive reaches for outer and inner boundaries are shown in Figure 39, Table
Table 35.
