Section 7
Testing functionality
7.4.12.1

Verifying the settings

1. When CCRPLD is set for external, set setting
Settings/IED Settings/Current/CCRPLD/CCRPLD:1 to activate the logic that detects
pole discordance when external pole discordance signaling is used (input EXTPDIND) in
the application configuration.
2. Activate the input EXTPDIND on CCRPLD function block, and measure the operating time
of CCRPLD.
3. Compare the measured time with the set value
4. Reset the EXTPDIND input.
5. When CCRPLD is set for unsymmetrical current detection with CB monitoring, set setting
CurrSel under Main menu/Settings/IED Settings/Current/CCRPLD/CCRPLD:1 to On .
Use the TRIP signal from the configured binary output to stop the timer.
6. Repeat point 4 and 5 using OPENCMD instead of CLOSECMD. Set all three currents to
110% of
NO TRIP signal should appear due to symmetrical condition.
7.4.12.2

Completing the test

Continue to test another function or end the testing by setting the parameter
under Main menu/Tests/IED test mode/TESTMODE:1. If another function is tested, then set
the parameter
CCRPLD(52PD)/CCRPLD:X for the function, or for each individual function in a chain, to be
tested next. Remember to set the parameter
has been tested.
7.4.13

Broken conductor check BRCPTOC

Prepare the IED for verification of settings as outlined in section
settings".
Values of the logical signals for BRCPTOC are available on the local HMI under Main menu/
Tests/Function status/Current/BRCPTOC(46,lub)/BRCPTOC:X. The Signal Monitoring in
PCM600 shows the same signals that are available on the local HMI.
7.4.13.1

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
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
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.
