Broken conductor check BRCPTOC
Prepare the IED for verification of settings outlined in section
.
10.4.14.1
Measuring the operate and time limit of set values
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.
