Continue to test another function or end the test by changing the TestMode setting to
Off. Restore connections and settings to their original values, if they were changed for
testing purposes.
10.10.2 Autorecloser for 1/2/3-phase operation SMBRREC
Verification of the Autorecloser for 1/2/3-phase operation function SMBRREC for
single-phase, two-phase or 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 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 outlined in section
"Preparing the IED to
verify settings".
The purpose of verification before commissioning is to check that entered selections,
setting parameters and configuration render the intended result. The function is
