Synchrocheck, energizing check, and synchronizing
SESRSYN
The Synchronizing function allows closing of
asynchronous networks at the correct moment including
the breaker closing time, which improves the network
stability.
Synchrocheck, energizing check, and synchronizing
(SESRSYN) function checks that the voltages on both
sides of the circuit breaker are in synchronism, or with
at least one side dead to ensure that closing can be
done safely.
SESRSYN function includes a built-in voltage selection
scheme for double bus and 1½ breaker or ring busbar
arrangements.
Manual closing as well as automatic reclosing can be
checked by the function and can have different settings.

For systems, which can run asynchronously, a
synchronizing feature is also provided. The main
purpose of the synchronizing feature is to provide
controlled closing of circuit breakers when two
asynchronous systems are in phase and can be
connected. The synchronizing feature evaluates voltage
difference, phase angle difference, slip frequency and
frequency rate of change before issuing a controlled
closing of the circuit breaker. Breaker closing time is a
setting.
Autorecloser SMBRREC
The auto recloser (SMBRREC) function provides:
• high-speed and/or delayed auto reclosing
• single and/or three phase auto reclosing
• support for single or multi-breaker applications.
The auto recloser can be used for delayed busbar
restoration.
Up to five reclosing shots can be performed. The first
shot can be single-, two-, and /or three-phase
