ABB’s SYNCHROTACT 4 device exited production in
2010 and is in the limited phase of its life cycle.
Inventory of spares and device availability cannot be
guaranteed at this stage. Securing the plant life cycle
by retrofitting to the SYNCHROTACT 6 will keep
assets productive, safe and reliable.
Upgrade benefits
• Long-term availability of parts
• Minimum shutdown and commissioning time: the
SYNCHROTACT 6 has similar mechanical
installation dimensions and the same electric
control concept as its predecessor
• Long-term availability of engineering and support
competences, including 24/7 telephone support
Launched at the beginning of 2018, SYNCHROTACT 6
is the sixth generation of ABB’s proven and popular
synchronizing technology. Over 22,000
SYNCHROTACT units have been sold since its
introduction, more than any other synchronizer on
the market.
The SYNCHROTACT portfolio is the most
comprehensive on the market, extending from the
smallest to the largest power requirements and
covering all power generation applications.
Typical applications
• Power plants with machines of any type
up to 2000 MW
• Thermal power plants (diesel, gas, steam),
including combined cycle and nuclear power
• Hydropower plants, including pumped storage
• Industrial plants with own power generation
• Grid paralleling in substations and islanded
power networks
• Large AC motors, soft-started and running above
nominal speed by means of a drive and then
synchronized during coast down
SYNCHROTACT 6 features
• The latest generation has two diversely
constructed channels in the same device. The
channels operate with different hardware and
software, to minimize the danger of a systematic
error. They also monitor each other
• State-of-the-art communication protocols,
including IEC 61850 Ed. 2, offers a choice between
an electrical or optical interface
• IEC 60255-26, IEC 60255-27 and ANSI/IEEE C37.90
product standards for protection and measuring
relays
• The unit’s robust design is in accordance with the
IEC 61508 SIL2 safety integrity level
