11.5.13 Broken conductor check BRCPTOC (46)
Prepare the IED for verification of settings as outlined in section
section "Preparing for test"
11.5.13.1 Measuring the trip and time limit of set values
1. Check that the input logical signal BLOCK to the BRCPTOC (46) function block is logical zero
and note on the local HMI that the output signal TRIP from the BRCPTOC (46) function block
is equal to the logical 0.
2. Set the measured current (fault current) in one phase to about 110% of the set operating
current
Observe to not exceed the maximum permitted overloading of the current circuits in the
terminal.
3. Switch on the fault current and measure the operating time of BRCPTOC (46).
TRIP is controlled by Gate 13 in the configuration.
Use the TRIP signal from the configured binary output to stop the timer.
4. Compare the measured time with the set value
5. Activate the BLOCK binary input.
6. Switch on the fault current (110% of the setting) and wait longer than the set value
No TRIP signal should appear.
7. Switch off the fault current.
8. Set the measured current (fault current) in same phase to about 90% of the set operating
current
9. Switch on the fault current and wait longer than the set value
No TRIP signal should appear.
10. Switch off the fault current.
11.5.13.2 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.
