Verification of START value and time delay to operate
M16256-10 v5
1. Check that the settings in the IED are appropriate, especially the ST
ART
value and the definite time delay. Set StartFreqGrad, to a rather small
negative value.
2. Supply the IED with three-phase voltages at their rated values.
3. Slowly decrease the frequency of the applied voltage, with an increasing rate-
of-change that finally exceeds the setting of StartFreqGrad, and check that
the START signal appears.
4. Note the operate value and compare it with the set value.
5. Increase the frequency to rated operating conditions, and zero rate-of-change.
6. Check that the START signal resets.
7. Instantaneously decrease the frequency of the applied voltage to a value about
20% lower than the nominal value.
8. Measure the time delay for the TRIP signal, and compare it with the set value.
Extended testing
M16256-29 v4
1. The test above can be repeated to check a positive setting of StartFreqGrad.
2. The tests above can be repeated to check the time to reset.
3. The tests above can be repeated to test the RESTORE signal, when the
frequency recovers from a low value.
11.7.3.2 Completing the test
M16256-39 v4
Continue to test another function or end the test by changing the TESTMODE
setting to Off. Restore connections and settings to their original values, if they were
changed for testing purposes.
11.8 Multipurpose protection
SEMOD53552-1 v1
11.8.1 General current and voltage protection CVGAPC
SEMOD56488-3 v3
Prepare the IED for verification of settings as outlined in section
"Requirements"
and section "Preparing for test" in this chapter.
One of the new facilities within the general current and voltage protection function
CVGAPC is that the value, which is processed and used for evaluation in the
function, can be chosen in many dif
ferent ways by the setting parameters
CurrentInput and VoltageInput.
These setting parameters decide what kind of preprocessing the connected three-
phase CT and VT inputs shall be subjected to. That is, for example, single-phase
quantities, phase-to-phase quantities, positive sequence quantities, negative
sequence quantities, maximum quantity from the three-phase group, minimum
