2. Supply the IED with three-phase voltages at rated values.
3. Slowly decrease the magnitude of the applied voltage, until the BLKDMAGN signal
appears.
4. Note the voltage magnitude value and compare it with the set value
5. Slowly decrease the frequency of the applied voltage, to a value below

Verifying the settings

Verification of START value and time delay to operate
1. Check that the IED settings are appropriate, for example the start value and the time
delay.
2. Supply the IED with three-phase voltages at their rated values and initial frequency.
3. Slowly increase the frequency of the applied voltage with a 40 mHz step, applying it for a
period that is 10% longer than
4. Note the operate value and compare it with the set value.
5. Decrease the frequency to rated operating conditions.
6. Check that the START signal resets.
7. Set the frequency to 20 mHz under the operate value.
8. Increase the frequency with a 40 mHz step, applying it for a period that is 10% longer
than
9. Measure the time delay for the TRIP signal, and compare it with the set value. Note that
the measured time consists of the set value for time delay plus minimum operate time of
the start function (80 - 90 ms).
Extended testing
1. The test above can be repeated to check the time to reset.
Verification of the low voltage magnitude blocking
1. Check that the settings in the IED are appropriate, for example the
the
2. Supply the IED with three-phase voltages at their rated values.
3. Slowly decrease the magnitude of the applied voltage, until the BLKDMAGN signal
appears.
4. Note the voltage magnitude value and compare it with the set value.
