Testing functionality
1. Keep the measured current as close as possible to its rated value or lower. Keep it
constant during the test, but ensure that it is higher than the set minimum operating
current.
2. Ensure that the maximum continuous current to the IED does not exceed four times its
rated value, if the measurement of the operating characteristics runs under constant
voltage conditions.
3. Make the necessary connections and settings of the test equipment for test of point 1
according to figure 16.
4. Decrease the measured three-phase impedance slowly and observe the operation value
for the signal ZOUT.
5. Compare the operation value with the set value.
6. Do the necessary change of the setting of the test equipment and repeat step
5 for point 2, 3 and 4 according to figure 16.

Testing the power swing detection function ZMRPSB

Preconditions
The following output signals shall be configured to binary outputs: ZOUT, measured
impedance within outer impedance boundary, ZIN, measured impedance within inner
impedance boundary and START, power swing detection.
1. Slowly decrease the measured impedance in all three phases until the START signal gets
activated.
2. Increase the measured voltages to their rated values.
3. Decrease instantaneously voltages in all three phases to the values, which are
approximately 20% lower than the voltage that gives the set value
predefined test current.
4. The START signal must not appear.
5. Increase the measured voltages to their rated values.
7.3.5.3 Testing the
Preconditions
• The input I0CHECK, residual current (3I
be configured to the output signal STPE on the FDPSPDIS function.
• The input BLKI02, block inhibit of the start output for subsequent residual current
detection is connected to FALSE.
1. Program the test equipment for a single-phase to earth fault and energize FDPSPDIS and
check that the input BLOCK on the power swing detection function ZMRPSB is activated.
2. Make a test sequence so that a single-phase to earth fault occurs after that the trajectory
of the impedance has passed the outer and inner boundary of ZMRPSB during power
swing. Use the result from test of ZMRPSB above to determine when the fault shall be
applied. The earth-fault must be activated before
3. Start the sequence and observe that the START signal will not be activated.
7.3.5.4

Completing the test

Continue to test another function or end the testing by setting the parameter
under Main menu/Tests/IED test mode/TESTMODE:1. If another function is tested, then set
the parameter
ZMRPSB(68)/ZMRPSB:1 for the function, or for each individual function in a chain, to be tested
