Sir , The Reality of Synchronization or Synchronism in respect of Alternators , You made to realize via this Video while explaining the "load angle limit" . Anyways Synchronization is somewhat naturally highlighted in case of Synchronous Motors - I mean the trend is like that . However , synchronization in respect of alternators , is somewhat limited to that Infinite Busbar (Constant Voltage & Constant Frequency) Concept only & this realistic approach of yours , truly excellent Sir .
No doubt for today Sir . Outstanding Explanation . CT 2ndary Rating Query I am yet to understand Sir whereas Induction Motor Unbalanced Currents how exactly causes overheating that also I have asked .
@@ElectricalTalks Yes Sir : Earth Leakage Earth Fault along with Induction Motor Overload & Overcurrent basic differentiation - These 2 also I have asked Sir .
@@ElectricalTalks Thank You Sir , I have also tried to develop my understanding about the basic difference between Earth Leakage & Earth Fault which is as follows : 1/ Earth Leakage is the condition where non-current carrying metallic surface of an equipment gets electrically charged due to failure of the internal insulation of the equipment & Earth Leakage Relay basically provides tripping against it in 30 mA range which is the limitation of human body to feel electric shock . To ensure no shock to human , Equipment Body Earthing is done ; I mean leakage current takes the low resistance path provided by the earthing & the human touching the charged equipment surface gets saved from electric shock . 2/ Earth Fault is the Condition where current carrying part of an equipment forms an inadvertent contact with the ground & Earth Fault Relay basically provides tripping against this short circuit current . To ensure no damage to the equipment , System Neutral Earthing is done ; I mean earth fault current takes the low resistance path provided by the neutral earthing & the equipment gets saved from damage . In fact , Neutral Earthing has got nothing to do with Short Circuit Fault between live phase conductors . My Understanding may please be reviewed & acknowledged Sir . But I am of course eagerly waiting for release of your video in the same context .

Your confusions are very obvious. These are on the basis of practical limitations of the generator. Generator manufacturer gives instruction about these values. Those are not calculated. And Thanks for your appreciation & keep learning....
Very basic but interesting question. For large alternators connected to grid, just increase the mechanical input, For thermal units, increase the steam inflow to turbine. The output of the alternator will increase accordingly maintaining the grid frequency. Its bit tough to understand thie answer through comments. If you understand. Its nice. Otherwise you may ask again.

Excellent explanation with outstanding animation. Learnt the concept of Generator capability curve after many years.
Glad it was helpful!
nice explanation
Thanks...
Difficult concepts explained in simplistic manner🙏

Thanks buddy
You made it very easy to understand, with your hard work , I appreciate and respect.
So awesome content and very easy to understand
Thanks
Explained very well. Why have you stopped making videos on the channel?.
Very good. Thanks 🙏🙏🙏🙏🙏🙏🙏
Very nice explanation
Nice presentation... Can u make one video to understand how to draw capability curve.
Thanks for clear concept.
Thanks
Thank you so much sir 🙏
Most welcome
How it is applicable in case of solar PV module generation system
This is for thermal power plant generators
No doubt for today Sir . Outstanding Explanation . CT 2ndary Rating Query I am yet to understand Sir whereas Induction Motor Unbalanced Currents how exactly causes overheating that also I have asked .
I will try to answer your queries as soon as possible.
@@ElectricalTalks Yes Sir : Earth Leakage Earth Fault along with Induction Motor Overload & Overcurrent basic differentiation - These 2 also I have asked Sir .
At the end of this month, I will publish a Q&A video on that your doubt & questions will be answered.

You are absolutely correct 👍

Nice vedeo sir,only certain doubt remain such as 120mvar,20mvar and 50mvar calculation .how did the value was calculated
Your confusions are very obvious. These are on the basis of practical limitations of the generator. Generator manufacturer gives instruction about these values. Those are not calculated.
And Thanks for your appreciation & keep learning....
Lekin sir practically generator ko unity pf pe kyo nhi chalate hai max pf 0.91 to 0.95 tak hi rakhte hai aisa kyo
good question. Its depends on system demand.
Active power/pf= MVA
not MVar
Yes. Its my mistake
bus reactor and line reactor explained
In case of lagging pf var may increase upto120 mvar but for leading pf on 50 mvar gen heating limitation is coming how??plz explains
Nice one. It will be discussed
Please explain this doubt sir
Is that 247 MVA or MVAR sir!
247 MVA
Right.. it's MVA
dear sir,
247 mvar kis waqt dey skta he?
thanks
Its 247 MVA brother, not mvar
Sir
Out put 247 Mvar lika hows he
210/0.85=247 MVA he
Sir
Jb 210 mw genration ho raha hota he
Us waqt 120 mvar b system me inject horaha hota he
Plz ye specify kren
How to increase load in alternator.
Very basic but interesting question.
For large alternators connected to grid, just increase the mechanical input, For thermal units, increase the steam inflow to turbine.
The output of the alternator will increase accordingly maintaining the grid frequency.
Its bit tough to understand thie answer through comments.
If you understand. Its nice. Otherwise you may ask again.
U didn't tell this condition is true only in gen parallel operation not in single operation.
