 Motor
Bus Transfer SystemsMaintain Plant Process! Avoid motor damage and costly shutdowns by ensuring the orderly transfer of the sources to your motors. Our complete SyncrotranŽ System and component relays properly execute the transfer of your critical motor loads.
Synchronizing Systems
Synchronizing systems are designed to provide both a manual and an automatic synchronizing function for one generator or multiple generator breakers. Control switches in the front panel provide for manual raising and lowering of both speed and voltage of the generator in order to match the bus frequency and voltage prior to synchronizing. Digital frequency meters and volt-meters provide both generator and bus measurements. An operator is assisted during manual synchronizing by both a synchroscope and synchronizing lights. Synchronizing Systems typically include: a Generator Control Unit that automatically matches generator frequency and voltage levels to those of the bus; a Syncrocloser Unit that sends the closing command to the breaker at the precise moment of phase coincident; and a Syncrocloser Check relay that provides a permissive function, verifying that voltage and phase angle conditions are within preset limits before allowing the breaker to close.
