I was searching this type of video... In which all the information about excitation system has been covered.... And finally I found this... No bakavaas only to the point u make me understand

[@ALOKKUMAR-ln1oy]

U demonstrate things very smartly and clearly so that anyone can understand easily and quickly....thanks a lot for the lectures ❤❤

[@dee309sammansaha6]

Sir your explanation is so good that i am able to explain this topic to any other of my friends. Thank you sir ❤️. Love from bengal

[@er.jogendargarhwal1795]

Sir working in industry
1.) AVR is hardly 20 cm *20 cm pcb (not big in size) for 4 MW generator
But as AVR is taking feedback from output voltage of main alternator we can't fix it on rotor
3.) Main exciter has high frequency ( using more number of poles) so that we can get smoother AC for main field without filters

[@Juyal_K]

[@thepurposeofmyexistence2511]

nice video sir , but I think reason behind making avr out side is that for the input wires coming from the load we can't connect directly to some moving part inside rotor

[@shubhamverma3875]

Thanks bro very useful

[@akshayporate7262]

Best explanation given by you sir, Is it possible for you to explain this with circuit diagram the thing is that i want to simulate brushless excitation system in a power electronics simulation software.

[@AkashKumar-sw6rb]

Great Sir

[@arbazansari7647]

Maybe there is a confusion in this lecture, from my knowledge split ring use to make DC output, and slip ring is use to make AC output. But in this lecture its reverse, kindly correct me if I am wrong.

[@techinsight1418]

Slip rings are of 2 types.... Split and complete.....
Split - for dc output
Complete - for ac
Generally we call complete ring as slipring.... And broken ring as split ring...
These are just conventional names...
Concept is same.... Complete ring or slipring for ac.... And split ring for dc

[@haritripathi302]

why cant pilot exciter field be directly used to main exciter in dc excitation system?

[@deshmukhdatta8564]

good exaplain

[@electricalaspirantshub6259]

Sir power speed relatiom kaise niklega is par video ka deep analysis,,parrallael operation par bhi

[@shashankyadav8707]

thank you sir🥰

[@pawankumar-mp5gy]

Good job👍💯

[@VijayKumar-gz5gu]

But the main drawback of brushless excitation system is the response time is large as compared to static excitation system.

Sir excitation control panel ke bare me jankari de please

[@bittuelectricalwork387]

Sir please make video on agra made alternator with turn ratio calculation.in this type of alternator have two winding in one pole shoe,one is the thik wire winding and another one is thin wire winding.i need pole shoe winding turn ratio calculation for constant voltage supply

[@mdtasnim9470]

why dc shunt generator which produces dc is not directly connected to rotor winding of alternator. why separately excited generator is used.

[@sanjeevrana8317]

Make video on excitation system of hydro power plant generator

[@bittuelectricalwork387]

This type of alternator will have two bridge rectifier and capacity will be 3kv,5kva,7.5kva,10kva and so on

[@bittuelectricalwork387]

If it is posible i will give you some photo of alternator and its field windings

[@saurav6148]

What is the input to avr? Is it from pilot excitor or from alternator output?

[@AnandKumar-dd2eo]

Good Information. I have a question though. In a brushless excitation system, why cant the pilot exciter be eliminated and output of alternator connected to controlled rectifier which will in turn control the field winding of the main exciter?

[@dee309sammansaha6]

As we know that the avr is a very sensitive device we don't want any type of convenice. The ac we get from the armature viz dc through the scr is rotating dc and if we want to give the static dc to the field winding of the avr we still need brush and slip rings. So ultimately we can not remove the picture of slip ring so we don't use the excitation from the alternator. Thank you

[@er.jogendargarhwal1795]

Because when we initially start the alternator we need some source of power.
Same is needed after blackout
Pilot excitor is of very smal capacity generally of size of pedestal bearing so it gives us self sufficiency for starting the system

[@er.jogendargarhwal1795]

​@@dee309sammansaha6AVR don't have field winding Mr it is a small PCB having PID and taking reference from output voltage of main alternator

[@sushantshekhardubey7345]

Explained beautifully 🙏

[@antonypt1829]

Sir pls send me 230volt portable brush less alternater winding diagram.

[@bijulal7497]

[@syedhassnainali2917]

S, please tell me about kvar and kva in generator

[@techinsight1418]

Kva is the unit of total apparent power [actice + reactive ] developed by generator.
Kvar is the reactive power supplied by generator.

[@geoblungamer4606]

Sir op❤

[@mukeshsah6306]

nice explanation. Thank you

[@psharavan143]

U explained 3 types of excitation , among them which one is double excited and which one is self excited.....plz confirm Me sir plz....

[@dee309sammansaha6]

Double excitation is the dc excitation and self excitation is static one.
