5. Activate the CBOPEN input signal.
6. Slowly decrease the injected current below the CurrStartLevel value until the
START signal disappears.
7. Compare the current magnitude value to the set value.
Verification of voltage band limit check logic
1. Ensure that the settings in the IED are appropriate to the default settings,
especially the CurrStartLevel, FreqHighLimit, FreqLowLimit, UHighLimit and
ULowLimit settings.
2. Ensure that the EnaVoltCheck is enabled.
3. Supply the IED with three-phase currents and voltages at their rated values.
4. Check that the VOLTOK signal appears.
5. Slowly decrease the frequency of the applied voltage until the START signal
appears.
6. Slowly decrease the positive-sequence voltage of the injected voltage below
the ULowLimit value until the START signal disappears.
7. Check that the VOLTOK signal disappears.
8. Compare the reset value to the set voltage low limit value.
9. Readjust the positive-sequence voltage of the applied voltage to a value within
the set voltage band limits.
10. Check that the START signal reappears.
11. Slowly increase the positive-sequence voltage of the injected voltage above
the UHighLimit value until the START signal disappears.
12. Compare the reset value to the set voltage high limit value.

Completing the test

• Continue to test another function or end the test by changing the Test mode
setting to off.
• Restore connections and settings to their original values if they were changed
for testing purposes.

Multipurpose protection

General current and voltage protection CVGAPC

Prepare the IED for verification of settings as outlined in section
and section "Preparing for test"
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 different ways by the setting parameters
CurrentInput and VoltageInput.
