Completing The Test; Fuse Failure Supervision Vdspvc - ABB Relion 670 Series Commissioning Manual

Section 11
Testing functionality by secondary injection
1. Simulate normal operating conditions with the three-phase currents in phase with their
corresponding phase voltages and with all of them equal to their rated values.
2. Change the voltages and currents in all three phases simultaneously.
The voltage change must be higher than the set value
be lower than the set value
•
•
3. Apply normal conditions as in step 1.
The BLKU, BLKZ and 3PH signals should reset, if activated, see step
4. Change the voltages and currents in all three phases simultaneously.
The voltage change must be higher than the set value
be higher than the set value
The BLKU, BLKZ and 3PH signals should not appear.
5. Repeat step 2.
6. Connect the nominal voltages in all three phases and feed a current below the operate
level in all three phases.
7. Keep the current constant. Disconnect the voltage in all three phases simultaneously.
The BLKU, BLKZ and 3PH signals should not appear.
8. Change the magnitude of the voltage and current for phase 1 to a value higher than the
set value
9. Check that the start output signals STDUL1 and STDIL1 and the general start signals
STDU or STDI are activated.
10. Check that the start output signals for the current and voltage phases 2 and 3 are
activated by changing the magnitude of the voltage and current for phases 2 and 3.

Prepare the IED for verification of settings as outlined in section
section
Checking the operation of binary input and output
1. Simulate normal operation conditions with three-phase voltage on the main fuse group
and the pilot fuse group. Ensure the values are equal to their rated values.
2. Disconnect one of the phase voltage from the main fuse group or the pilot fuse group.
Observe the binary outputs of the IED. The MAINFUF or the PILOTFUF signals are
simultaneously activated. Only the output circuit related to the open phase will be active
i.e either MAINFUF or PILOTFUF.
3. Establish a normal voltage operating condition and observe the corresponding output
signals. MAINFUF or PILOTFUF should change to
4. Set normal conditions as mentioned in step 1.
5. Enable the BLOCK binary input and repeat step 2. MAINFUF or PILOTFUF should not
appear.

The BLKU and BLKZ signals appear without any time delay. The BLKZ signal will be
activated only if the internal deadline detection is not activated at the same time.
3PH should appear after 5 seconds, if the remaining voltage levels are lower than
UDLD< of the dead line detection function.
