1. Quickly set the measured current (fault current) in one phase to about 300% of
IRef (to
minimise the trip time), and switch the current off.
2. Reset the thermal memory on the local HMI under Main menu/Reset/Reset
temperature/ThermalOverload1TimeConst(PTTR,26)/LFPTTR:x, Main menu/Reset/
Reset temperature/ThermalOverload1TimeConst(PTTR,26)/LCPTTR:x,
3. Switch the fault current on and take note of the temperature, available on the local HMI
under Main menu/Test/Function status/Current protection/
ThermOverLoad1TimeConst(PTTR,26)/LFPTTR:x/TEMP, Main menu/Test/Function
status/Current protection/ThermOverLoad1TimeConst(PTTR,26)/LCPTTR:x/TEMP,
4. Check the time until the actual temperature TEMP has reached the
AlarmTemp level
during injection.
Monitor the signal ALARM until it appears on the corresponding binary output or on the
local HMI.
5. Measure the LCPTTR/LFPTTRprotection trip time.
Use the TRIP signal from the configured binary output to stop the timer.
6. Take the TEMP readings.
Compare with the setting of
TripTemp.
7. Activate the BLOCK binary input.
The signals ALARM, START and TRIP should disappear.
8. Reset the BLOCK binary input.
9. Check the reset limit (TdReset).
Monitor the signal START until it disappears on the corresponding binary output or on
the local HMI, take the TEMP readings and compare with the setting of
ReclTemp.
10. Compare the measured trip time with the setting according to the formula.
11. Reset the thermal memory.
12. Continue to test another function or end the test by changing the test mode setting to
Off.
9.3.6.2 Completing the test
M14950-48 v5
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.
9.3.7 Breaker failure protection, phase segregated activation and
output CCRBRF
M12104-2 v13
Prepare the IED for verification of settings outlined in Section "Preparing the IED to verify
settings" .
The Breaker failure protection, 3-phase activation and output function CCRBRF should
normally be tested in conjunction with some other function that provides a start signal. An
external START signal can also be used.
To verify the settings in the most common back-up trip mode
1 out of 3, it is sufficient to test
phase-to-earth faults.
At mode 2 out of 4 the phase current setting, IP> can be checked by single-phase injection
where the return current is connected to the summated current input. The value of residual
(earth fault) current IN set lower than
IN> is easiest checked in back-up trip mode 1 out of 4.
9.3.7.1 Checking the phase current operate value,
IP>
M12104-23 v14
The check of the
IP> current level is best made in FunctionMode = Current and BuTripMode = 1
out of 3 or 2 out of 4.
