ABB Relion 670 series - Completing the Test; Function Revision History; General Current and Voltage Protection CVGAPC; Multipurpose Protection

1. The test above can be repeated to check a positive setting of PickupFreqGrad.
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.

Continue to test another function or end the test by changing the TESTMODE setting to Disabled.
Restore connections and settings to the original values, if changed for testing purposes.

J 2.2.5 • The harmonic restraint function changed to freeze the definite and IDMT timers.
• The maximum value of the settings IMin1 and IMin2 has been decreased to 1000.0 %
of IBase.
• Setting BlkLevel2nd was removed from the function.
• Previously called stepwise settings t_DefOCx and tResetDef_OCx had their names
changed to t_OCx and tReset_OCx for more clear understanding.
11.9.2 General current and voltage protection CVGAPC
SEMOD56488-3 v4
Prepare the IED for verification of settings as outlined in section "Requirements" and section "Preparing
for test" in this chapter.
One of the 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 different 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 quantity from the three-phase group, difference between maximum and minimum
quantities (unbalance) can be derived and then used in the function.
