Verifying the signal and settings

Measure the operating characteristics during constant current conditions. Keep the measured current as
close as possible to the rated value of the IED or lower. Ensure that it is higher than the set minimum
operating current.
Ensure that the maximum continuous current to the IED does not exceed four times of its rated value, if
the measurement of the operating characteristics runs under constant voltage conditions.
The test is mainly divided into two parts, one aim is to verify that the settings are in accordance with the
selectivity plan and another aim is to verify the operation of ZMBURPSB.
Before starting this testing process, all impedance measuring zones shall be set and in operation. Ensure
that the inner zone of ZMBURPSB must cover all impedance measuring zones that are set for operation.
Test of the interactions or combinations that are not configured are not considered in this instruction.
Always set Operation to On to check the performance of power swing detection, blocking and unblocking
during testing.
Testing the operating characteristics
Preconditions
The following output signals shall be configured to binary output available: ZOUT, measured impedance
within outer impedance boundary and ZIN, measured impedance within inner impedance boundary.
1. Set X1InFw, R1LIn, X1InRv, R1FInFw, R1FInRv, ArgLd, RLdOutFw, RLdOutRv, kLdRFw and
kLdRRv to values that are in accordance with the selectivity plan and the corresponding operating
characteristic is as shown in Figure 39.
2. Set OperationLdCh to On.
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
