9.3.9 Broken conductor check BRCPTOC
SEMOD175021-3 v5
Prepare the IED for verification of settings as outlined in section "Requirements" and
section "Preparing for test" in this chapter.
9.3.9.1 Measuring the operate and time limit of set values
SEMOD175021-7 v6
1. Check that the input logical signal BLOCK to the BRCPTOC function block is logical zero
and note on the local HMI that the output signal TRIP from the BRCPTOC 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
IP>.
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.
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
tOper.
5. Activate the BLOCK binary input.
6. Switch on the fault current (110% of the setting) and wait longer than the set value tOper.
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
IP>. Switch off the current.
9. Switch on the fault current and wait longer than the set value
tOper.
No TRIP signal should appear.
10. Switch off the fault current.
9.3.9.2 Completing the test
SEMOD175021-42 v4
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.
9.4 Voltage protection
SEMOD53540-1 v1
9.4.1 Two step undervoltage protection UV2PTUV
M13796-2 v6
Prepare the IED for verification of settings as outlined in section "Requirements" and
section "Preparing for test" in this chapter.
9.4.1.1 Verifying the settings
M13796-9 v3
Verification of start value and time delay to operate for Step 1
M13796-29 v10
1. Check that the IED settings are appropriate, especially the START value, the definite time
delay and the
1 out of 3 operation mode.
2. Supply the IED with three-phase voltages at their rated values.
3. Slowly decrease the voltage in one of the phases, until the START signal appears.
4. Note the operate value and compare it with the set value.
