Function
The Synchrocheck module recognizes and signals if the synchronism conditions exist
between two independent voltage sources (example: generator + network) for closing of the
interconnection circuit-breaker.
NOTE:
• The Synchrocheck functions are activated only in the presence of the Ekip
Synchrocheck module.
• All the operating specifications are described in the paragraph that describes the
Synchrocheck module, on page 171.
