Answer / kiran

polarities should be matched and relative speed between two
machines should be zero....

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 / monika hassan

The rating, phas sequence & speed of the both generators
should be same.

Answer / priya

the bus bar voltage of the two dc generator must be the same

Answer / abhishek

polarity, terminal voltage & drooping external char (Vt vs
Il).... if rising char. equalizer or cross connected fld is reqd

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 / devikumar

both voltages,phases and frequency same

Answer / paramesh

both generators having same voltage,phase
sequence,frequncy.then only we cpnnected two generators as a
parallel

Answer / bharat3832

those two machines should have same output voltage and in
same frequency
