ABB UNS 2980 Synchronizing devices SYNCHROTACT® 4 TO 6

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
