Chala baga chepparu sirrrr🎉

[@PalikaSekhar-df9pe]

Such as a great explanation sir

[@ElectricalEngineeringTelugu]

You are welcome

[@azeezsheik6254]

Please upload vedios on other dc generators also

[@ElectricalEngineeringTelugu]

Okay azeez

[@pallapupavankumar1597]

Superb explanation sir

[@ElectricalEngineeringTelugu]

You are welcome pavan kumar..

[@kishorechandaluri11]

Sir plz do video on commutation in DC generator

[@ElectricalEngineeringTelugu]

Okay, I will do..

[@kishorechandaluri11]

Sir I had some doubts how can I contact you sir ?

[@ElectricalEngineeringTelugu]

You post your mobile number here, I will call You..

[@shailajashailu920]

Hi andi, can you explain battery charger and batteries of substation

[@ElectricalEngineeringTelugu]

I will try to make a video on it in near future , don't worry, all the best.

OCC characteristics lo generated voltage =terminal voltage kadha sir ?

[@ElectricalEngineeringTelugu]

Yes.. you are 100% correct. To give some more exposure to you , i am giving you following explanation too.. Incase of separately excited dc generators, under noad load conditions, the terminal voltage is equal to induced e.m.f. Incase of self excited dc generators, under noad load conditions, the terminal voltage (Vt = Eg - Ia * Ra - b.c.d). Where Eg = induced e.m.f in armature Ia = armature current =field current ; because machine is self excited and load is zero Ra = armature winding resistance b.c.d = brush contact drop As, under no load ia = if only, as load current iL is zero. Ia is comparatively very low hence Ia * Ra and b.c.d are negligibly small. Hence terminal voltage is almost equal to induced e.m.f.
