Testing the voltage selection for single CB arrangements
This test should verify that the correct voltage is selected for the measurement in the
SESRSYN function used in a double-bus arrangement. Apply a single-phase voltage of
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.
6.8.1.5 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/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.
6.8.2 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)/X:SMBRREC .
The Signal Monitoring in PCM600 shows the same signals that are available on the
local HMI.
