ABB SYNCHROTACT ® 5 Synchronizing and Paralleling Equipment
SYNCHROTACT® 5 is the fifth generation of synchronizing equipment produced by ABB Switzerland Ltd in Switzerland. SYNCHROTACT products from ABB are used for automatic synchronization of generators with power lines and for paralleling of synchronous lines. They are designed for fully automatic operation by dual-channel or single-channel systems.
Synchronizing equipment are used in power stations where a generator needs to be paralleled with a power line or in substations to parallel two synchronous lines.
Power circuit breakers can only be closed if voltage at both ends is synchronous. If it is not, it will cause a disturbance in the power network, trip the breaker, shock the generator and unit transformer. In extreme cases, it can damage both.
SYNCHROTACT 5 guarantees a safe and reliable synchronization whether as a monitoring element for manual paralleling or as an independent fully-automatic synchronizing unit.
SYNCHROTACT 5 covers the following areas of application:
Automatic synchronization and paralleling of generators with power lines (see Fig. 1 below),
2. Automatic paralleling for synchronous and asynchronous lines and busbars (see Fig. 2 below),
3. Monitoring (Synchrocheck) of automatic or manual paralleling of power lines, generators and voltage-free lines (dead bus), see Fig. 3 below.
