SYNCHROTACT® Systems

Application

SYNCHROTACT® synchronizing cabinets can be designed specifically for customer requirements and are

used to synchronize generators and to parallel lines.

Depending on available space, other systems, as for example measuring and metering functions, may be

used in the same cabinet, in addition to the synchronizing system.

SYNCHROTACT® Systems

Typical configurations of a synchronizing system

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).
