Automatic Synchronizer (Optional)
Two methods of generator synchronization are offered: phase lock loop and anticipatory
A . In both
methods, the DGC-2020 adjusts the frequency and voltage of the generator to match that of the bus
(mains) and then connects the generator to the bus by closing the breaker. Anticipatory mode has the
added capability of compensating for the breaker closing time (the delay between when a breaker close
command is issued and the breaker blades close). The DGC-2020 calculates the advance phase angle
