Answer / k.prakashchandra

Size , capacity do not matter ?

Answer / e.subhash

If a.C generator means

The following condition should be same before synchronizing the generator (whatever it may be it's size)
1) bus voltage and machine voltage
2) bus frequency and machine frequency
3) bus and machine phase sequence
4) phase angle

The following method is using for synchronizing.
1) dark lamp method
2) bright lamp method
3) synchroscope method

Answer / tasawar abbas suddle

When I sync. the two more than generator we must knowledge of the generator like as its frequency, phase seq, voltage magnitude & phase angel. and its capacity is also same.

if these generator capacity not same then when i start the generator will give the power to the system the other generator is small when big generator give the power to system and the other small generator will absorbed the power and it work like as motor.
and the second small generator will also absorbed power there is no benefit

I have an existing old MCCB. ABB Model SACE, the rating are: Ue = 660 volts, Iu =1250 Amps, 3 poles, Ith (max) =800 amps at 45 deg C. I need a circuit breaker for my 3 phase motors, 380 volts 60 hz. the supplier required the minimum ampacity of the breaker to be 911 amps. can i use this breaker with rating of Iu =1250 amps but Ith = 800amps maximum?
