The system uses proven SYNCHROTACT® 5-components
and may be individually adapted. Typical configurations are as
follows:
1. Safety: Single- or dual-channel solutions
2. Availability: Redundant manual synchronizing or redundant
automatic synchronizing or both
3. Number of circuit breakers to be synchronized: up to four circuit
breakers, one or more of which may be generator breakers
4. Power supply: In case of redundant synchronizing, the
power supply on the cubicle entrance can be redundant too.
5. Synchronizing control: Remote, local or both
6. Adaptation of the measuring voltages: Especially with
synchronizing of several circuit breakers it may occur that the
two secondary voltages have different amplitudes and
phase angles with closed circuit breaker.
Examples of synchronizing concepts
Automatic synchronizing (sketch shows dual channel version)
including separate synchrocheck for redundant manual
synchronizing (with its own hardware and power supply).
Redundant, automatic dual channel synchronizing with
the additional possibility of a manual synchronizing (using
parameter set 7).
