Synchronizing Panel are used when there is three or more power source are connected to the common busbar like one  main power supply and two or more DG are installed. These panels are usually seen in shopping malls, airports, seaports, hospitals large industries etc. During main power fails, AMF Panel will start the DG: 1 automatically if the load exceeds more than 90% in DG: 1 synchronizing relay gave command to start DG:2 and DG:2 will start automatically.  The synchronization relays checks the parameters like magnitude of Voltage, Phase angle and Frequency if the all are the three parameters matches then the relay will give command to start the DG-2 incomer breaker in Main Panel to synchronize the operations.
