Dear chetan, Yes, you can run two alternator in parallel but there is some necesosory condition which your must have to fulfill. 1. Phase(terminal) Voltage must be same. This is obtained by adjustment of the incoming generator’s field strength. 2.Frequencymust be same. This is obtained by adjustment of the incoming generator’s prime-mover speed. 3. Phase sequance must be same.

@nkur Posts: 202 Rating: (16)	Dear jeet2907 All the points that you have mentioned are upto the mark but what about phase angle of different source does it has any effect on parallel operations of alternator???
