Sir please add all generator protections in details, for that you can make bigger videos if needed. Your videos are very useful and concept clearing also. Please continue your good work
Whenever load varies, it is because of current consumption increases instantly, we don't have control over current demand. Here torque is converted into current through mechanical input. As current consumption increases, voltage n pf reduce, reactive power increases, all of sudden AVR get signal of current demand, as reactive power communicate to AVR. So voltage increases simultaneously with governor increases mechanical power .so first response of variation always through AVR. My question is load increases, mean AVR will increase excitation, then how we will have control over rpm, practically what actually happening there. Is it because of armature reaction
I am an expert in this field but i can take a guess. I think AVR controls the excitation and not the governor . Excitation is controlled by varying field strength to rotor windings thereby controlling output voltage. It doesnot effect the mechanical rotation of turbine. Governor speed is controlled by turbine controllers and not AVR.
I never thought in my life I’d be here, yet here I am
Sir, very nice explain
On this topic one more videos with full explanationsize.
Thank you

During referring this capability curve, How minimum we can go down generator output voltage than design??
Very nicely described ! Great job bro!
If Under- Excitation Limiter Act alarm came in AVR system, What to do .
Very good. Thanks 😊🙏🙏🙏
can you elaborate on armature end heating, I don't see any reason for these heating!
Sir you are doing great.I have some queries regarding turbine efficiency. Please can you explain these.
Good work...pl upload more video on generator protection....
Dear sir can u please tell us how we can set the control regulated voltage limits nd fro limits with stab..!! please share if possible
Thanks sir. I understand clearly

sir plz explain about generator low forward power protection
super lecture sir
Sir plz upload rotor earth fault and pole sliiping video
