8. Change the magnitude of the voltage and current for phase 1 to a value higher than the set
value
9. Check that the pickup output signals PU_DV_A and PU_DI_A and the general pickup signals
PU_DV or PU_DI are activated.
10. Check that the pickup 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.
11.9.2.6 Completing the test
continue to test another function or end the test by changing the
Restore connections and settings to their original values, if they were changed for testing
purposes.
11.9.3 Fuse failure supervision
Prepare the IED for verification of settings as outlined in section
section "Preparing for test"
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.
Checking the operation of MAINFUF and PILOTFUF
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. Decrease one of the three-phase voltages on main fuse group or pilot fuse group. The voltage
change must be greater than the set value for
PILOTFUF signals are activated without any time delay.
3. Set normal conditions as mentioned in step 1. MAINFUF or PILOTFUF signals should reset.
4. Set
5. Apply three-phase voltages with the value slightly below
6. Decrease one of the three-phase voltages on main fuse group. The voltage change must be
greater than the set value for
7. After more than 5 seconds increase the measured voltage back to the value slightly below
VSealIn level. MAINFUF signal should not reset.
8. Slowly increase measured voltage to the value slightly above
resets.
9. Record the measured voltage and compare with the set value
