3. Control
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.
Apparatus control APC
The apparatus control functions are used for control and
supervision of circuit breakers, disconnectors and earthing
switches within a bay. Permission to operate is given after
evaluation of conditions from other functions such as

apparatuses is used for control and supervision of circuit
breakers, disconnectors and earthing switches within a bay.
Permission to operate is given after evaluation of conditions
from other functions such as interlocking, synchrocheck,
operator place selection and external or internal blockings.
Apparatus control features:
• Select-Execute principle to give high reliability
• Selection function to prevent simultaneous operation
• Selection and supervision of operator place
• Command supervision
• Block/deblock of operation
• Block/deblock of updating of position indications
• Substitution of position and quality indications
• Overriding of interlocking functions
• Overriding of synchrocheck
• Operation counter
• Suppression of mid position
Two types of command models can be used:
• Direct with normal security
• SBO (Select-Before-Operate) with enhanced security
Direct commands are received with no prior select command.
M13444-3 v15
SBO commands are received with a select command first and
on successful selection, a proceeding operate command.
