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 are running asynchronous, a
synchronizing function is provided. The main purpose of
the synchronizing function is to provide controlled
closing of circuit breakers when two asynchronous
systems are going to be connected. The synchronizing
function 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 parameter setting.
Autorecloser SMBRREC
The autorecloser SMBRREC function provides high-
speed and/or delayed auto-reclosing for single or multi-
breaker applications.
Up to five three-phase reclosing attempts can be
included by parameter setting. The first attempt can be
single-, two and/or three phase for single phase or
multi-phase faults respectively.
Multiple autoreclosing functions are provided for multi-
breaker arrangements. A priority circuit allows one
