Synchro-Check
SPRECON-E-C-SYNC
The synchro-check device measures two voltages with regard to phase, frequency and voltage difference in order to interconnect grids which are under voltage. SPRECON synchro-check may act as a decentralized or a centralized system. It can be either activated on request or used for continuous monitoring.
Various conditions can be defined for command output blocking. Beside the synchrocheck function, the voltages can be simultaneously monitored.
Command initiation for the circuit breaker is finally approved by the synchro-check, which monitors the synchronising condition as well as the voltages. This allows a secure reconnection of separated networks. The status of the synchro-check can be simultaneously requested. In this mode, only the current status (synchronous, asynchronous, dead line, dead bus) is indicated.
Beside application of SPRECON-E-C-SYNC as a stand-alone device, the synchro-check functionality can be also integrated into a SPRECON-E-C bay computer together with other control functions. Six parameter sets can be changed via commands or directly out of process.
