Synchronizers

A.T. GENERATORS Perform different types of synchronizing projects between the diesel generators.

• Direct upgrade/replacement using custom synchronizing panels

• Engineered upgrades of legacy synchronizing systems using automatic synchronizing relays

•  Engineered upgrades of synchronizing systems using utility-grade PLCs for multiplexing multiple generators

Synchronizing panel will operate on an automatic mains failure system, so that when the main supply is interrupted on one or all phases (after an adjustable delay period) the generator sets will start-up together. After an initial warm-up period (adjustable) the generators will synchronize with each other by means of motorized circuit breakers or contactors onto a common buss bar. Next, the motorized change-over switch will be closed and the load connected to the main distribution box.

The load share units continuously monitor the load and during low demand periods one or two generators will be shut down to save on fuel consumption. As demand rises again the second generator and third generator will be restarted, synchronized and reconnected to load. When the AMF control unit detects that the main supply has been restored an adjustable observation period is activated before the main supply is reconnected. A cool down period will then follow, after which the generator sets will be shut down.
