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

any one can explain the stages of a knee point which is taken during ct magnetising curve.

I hv a question regarding power factor improvement just after transformer. I request you to reply me plzz. thank you sir. My friend has a small unit of fabrication. in his factory the main load is a welding machine, lathe machine, grinding machine. this load is not continuous type. now our electricity board has installed 16 KVA, 11000/433 V transformer for our factory. In the energy meter (trivector meter) at LV side of transformer, i hv seen power factor value of 0.15 only when only 3 KW load was flowing. Further electricity board has suggested to install 4 KVAR capacitor at LV side after energy meter. Now my question is that if we permanantly install and switch on 4 KVAR capacitor after energy meter, during some load on transformer and also without any load on transformer, wht will be the power factor shown in energy meter?i dont want to get any penalty by electricity board, so plz suggest me if i can permanantly install and switch on the 4 kvar capacitor or not at LV side of transformer just after energy meter? Thank you again and awaiting for ur positive reply soon.
