Answer / bhavya
Its not actually the phase sequence in case of DC. its polarity i guess... and also the votage rating must be the same... i go with the answer 2

Answer / lucky
The following conditions must be satisfied for the paralleling of DC generators:
a. The polarities of the generators must be identical.
b. The terminal voltages must be the same.
c. The change of voltage with the change of load must be the same character.
d. The prime movers driving the armature of the generators must have similar and stable rotational characteristics.

Answer / paramesh
both generators having same voltage,phase
sequence,frequncy.then only we cpnnected two generators as a
parallel
Is This Answer Correct ? | 9 Yes | 10 No |
Answer / bharat3832
those two machines should have same output voltage and in
same frequency

Hello friends., my question is related to testing of current transformer... A Ct having knee point voltage of 750 volts., and I have two step up transformer's of rating 230 v to 440 volts., can I obtain the value of 750 volts by using the two transformer's.... If yes then how could I connect the transformer's to obtain knee point voltage?? thank you in advance
