Testing the voltage selection

Testing the voltage selection for single CB arrangements
This test should verify that the correct voltage is selected for the measurement in
the energizing check function used in a double-bus arrangement. Apply a single-
phase voltage of 100% UBase to the U-Line and a single-phase voltage of 100%
UBase to the U-Bus.
If the UB1/2OK inputs for the fuse failure are used, they must be activated, during
tests below. Also verify that deactivation prevents operation and gives an alarm.
1. Connect the signals above to binary inputs and binary outputs.
2. Connect the voltage inputs to the analog inputs used for each bus or line
depending of the type of busbar arrangement and verify that correct output
signals are generated.

Completing the test

Continue to test another function or end the testing by setting the parameter
TestMode to Off under Main menu/Tests/IED test mode/1:TESTMODE. If
another function is tested, then set the parameter Blocked to No under Main menu/
Tests/Function test modes/Control/SESRSYN(25,SYNC)/X:SESRSYN for the
function, or for 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.

Autorecloser SMBRREC

Verification of the Autorecloser function SMBRREC can be considered to consist
of two parts.
• One part to verify the internal logic and timing of the function
• One part to verify its interaction with the protection system
This section deals with verification of SMBRREC itself. However, it is practical to
start SMBRREC by activating a protection function, for example, by secondary
injection tests.
Prepare the IED for verification of settings as outlined in
verify settings".
Values of the logical signals for SMBRREC are available on the local HMI under
Main menu/Tests/Function status/Control/SMBRREC(79,0->1)/
X:SMBRREC. The Signal Monitoring in PCM600 shows the same signals that are
available on the local HMI.
The purpose of verification before commissioning is to check that entered
selections, setting parameters and configuration render the intended result. The
function is flexible with many options and facilities. At commissioning only the
