each individual function in a chain, to be tested next. Remember to set the parameter
Blocked to Yes , for each individual function that has been tested.
6.11 Testing monitoring functions
6.11.1 Event counter CNTGGIO
The event counter function CNTGGIO can be tested by connecting a binary input to
the counter under test and applying pulses to the counter. The speed of pulses must not
exceed 10 per second. Normally the counter will be tested in connection with tests on
the function that the counter is connected to, such as trip logic. When configured, test it
together with the function that operates it. Trig the function and check that the counter
result corresponds with the number of operations.
6.11.2 Fault locator LMBRFLO
Prepare the IED for verification of settings as outlined in 5.1 "Preparing the IED to
verify settings" .
Values of the logical signals for LMBRFLO are available on the local HMI under
Main menu/Tests/Function status/Monitoring/LMBRFLO/1:LMBRFLO . The
Signal Monitoring in PCM600 shows the same signals that are available on the local HMI.
The Fault locator function LMBRFLO depends on other functions to work properly,
that is, phase selection information from distance protection function and analog
information supplied by the trip value recorder function. Check that proper binary
initiate (pickup or tripping) and phase selection signals are connected and voltage and
current signals are configured (parameter settings).
The fault locator LMBRFLO function, supports kilometer and mile for
the line length unit. The fault distance will be presented with the same
unit as the line length and is mapped to IEC61850 -8-1 communication
protocol, where the fault distance is supposed to be in kilometer (km).
Select the line length unit to kilometer for compliance with IEC61850.
The result is displayed on the local HMI or via PCM600. Distances to faults for the last
100 recorded disturbances can be found on the local HMI under
Main menu/Tests/
Function status/Monitoring/LMBRFLO/1:LMBRFLO/Outputs
If PCM600 is used, the result is displayed on the recording list after upload, including
loop selection information.
