11.10.2 Autorecloser for 1/2/3-phase operation SMBRREC (79)
Verification of the auto recloser for single-phase, two-phase or three-phase auto reclosing attempts can
be considered to consist of two parts.
• One part to verify the internal logic and timing of the auto recloser
• One part to verify its interaction with the protection system
This section deals with verification of the auto recloser itself. However, it is practical to initiate the auto
recloser by activating a protection function, for example, by secondary injection tests.
Prepare the IED for verification of settings outlined in Section
The purpose of verification before commissioning is to check that entered selections, setting and
configuration render the intended result. The auto recloser 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 up verification, be careful to set the auto recloser at intended
operational values at the end of the verification procedure. One such parameter is the tReset time that
must be timed out before a new test sequence can be performed.
The verification test is performed together with protection and trip functions.
