Introduction - Controlled Switching with Switchsync
TM
Introduction Application
It should be noted that circuit breakers of
other design, e.g. using other types of mech-
anisms, may show larger variations in op-
erating times, statistically from operation to
operation, and also as a result of variations in
ambient temperature etc. It may therefore be
less beneficial to use such circuit breakers for
controlled switching applications. The dielec-
tric properties between the contacts, upon
making or breaking operations, may also be
less suitable.
For good results, and appropriate limitation
of the switching transients, we recommend
use of Switchsync
TM
controllers only with
ABB’s SF
6
live tank circuit breakers.

Switchsync
TM
for Condition
Monitoring
The Switchsync
TM
controllers F236, L183 and
T183 have integrated data memories that
store information on make times for a large
number of operations. This information may
be used for condition monitoring of the con-
trolled circuit breaker.
Experience
ABB has nearly 20 years of service
experience with controlled switching,
and the first generation of Switchsync
TM
controllers was launched in 1986. ABB is at
the forefront of development in this area and
has built up unique expertise in switching
transients and mitigation of related problems
in both main and secondary circuits, as well
as EMC aspects.
Presently, thousands of Switchsync
TM
controllers are in operation. More than
half of the applications are for capacitor
banks and harmonic filters, about 25% for
shunt reactors and about 15% for power
transformers.
Testing and standards
IEC is at the moment defining test require-
ments for circuit-breakers intended for con-
trolled switching applications. The outcome
of the IEC work will be published in Technical
report IEC 62271-302.
