30% GblBaseSelLine to the V-Line and a single-phase voltage of 100% GblBaseSelBus to
the V-Bus.
If the VB1OK or VB2OK 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.
6.7.1.5 Completing the test
Continue to test another function or end the testing by setting the parameter TestMode to
Disabled under Main menu/Tests/IED test mode/TESTMODE:1. If another function is
tested, then set the parameter Blocked to No under Main menu/Tests/Function test
modes/Control/SESRSYN(25,SYNC)/SESRSYN:X 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.
6.7.2 Autorecloser for 3-phase operation SMBRREC (79)
Verification of the Autorecloser for 3-phase operation function SMBRREC (79) for three-
phase reclosing attempts 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 (79) itself. However, it is practical to
initiate SMBRREC (79) by activating a protection function, for example, by secondary
injection tests.
Prepare the IED for verification of settings as outlined in
5.1 "Preparing the IED to verify
settings".
Values of the logical signals for SMBRREC (79) are available on the local HMI under
Main menu/Tests/Function status/Control/SMBRREC(79,0->1)/SMBRREC:X.
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 selections and settings
intended for use are verified. If one chooses to reduce some time settings in order to speed
