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.
The initial frequency is calculated using Equation 21.
StartFrequency

3. Slowly increase the voltage frequency by steps of 40 mHz until the START signal appears;
during each step apply the voltage signal for a time that is either at least 10% longer than
tDelay +100 ms) or a suitable time to monitor the function.
(
4. Note the frequency value at which the START signal appears and compare it with the set
value
5. Decrease the frequency until its rated value is reached.
6. Check that the START signal resets.
7. Supply the IED with three-phase voltages at their rated values and frequency 20 mHz
under the set value
8. Increase the frequency with a 40 mHz step, applying it for a time that is at least 10%
longer than (
9. Measure the time delay of the
that the measured time consists of the set value of the time delay plus the minimum
operate time of the function (80 - 90 ms).
Extended testing
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 frequency 20 mHz over
the set value
tDelay +100 ms).
(
3. Verify that the TRIP signal is active.
4. Decrease the frequency with a 40 mHz step, applying it until the TRIP signal resets.
5. Measure the reset time of the
function.
Verification of the low voltage magnitude blocking
1. Check that the IED settings are appropriate, especially the
in SAPTOF, and the
function.
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 value
UBase / 100.

5. Slowly increase the frequency of the applied voltage, to a value above
explained in Section
6. Check that the START signal does not appear.
