In gerator syncronisation there are follwoing three steps.
we will call machine to be syncronised as incoming machine
(1) same voltage
(2) same frequency
(3) same phase angle

Scoboscope is used for syancro. also there are another
method named 2bright 1 dark and vice vrsa.

The power angle delta between induced emf and terminal
voltage determines the power transfer.

Answer / lava kumar.v

1. Run first set to voltage and frequency and switch to the main bus bar
2.connect at least 25% Load if regulation is poor.
3.set upto voltage and frequency.
4.synchronize phasing up to bus bar manually or automatically

Above mentioned points are satisfied the Dg will ready for operation
* Adjust engine power as necessary if it takes most of the power it will go out over load ,This will bring down the system.
