I have naver seen such a good teacher ..... what a good method of teaching ....... salute sir
wa'alaikumussalaam
Hi Sir.. im Indonesian,
Useful Video about Generator
bery Nice n Thanks u👍
What an excellent explanation ! you are amazing in teaching Sir.. I'm a Maintenance Engineer from Srilanka.
Thanks
Great source of DG knowledge..thank you
Brother very nicely explained thanks
Well explained. Great. Like your lectures
Kia baaat h bht khoob ...
exceelent ..stay blessed keep working :-)
Thanks you sir 🙏
Great..... Sir
Good..keep it up👍
Excellent video bhai
Salut 🙋👍🏻👍🏻💪🏻💪🏻🙏🙏
thanks bhi
Nicely explained Sir..Just a req...if you can make a video in AVR circuit and how it works,that would be more useful and defects related to generrators.Thank you so much for so many educacative videos.
Great explanation sir
Superb 👌
Masha,Allah
Dear sir
AOA
We can only pray for your health and happiness, may GOD bless you.
I've one question
Suppose from AVR's output sensing volt is 30 volt dc to excitation stator then this excitation voltage convert it into AC VOLT then again this AC convert it into DC by rotating bridge rectifer , which will again same 30 volt dc? this dc provide to main rotor
AVR output Sensing volt and main rotor dc supply voltage from bridge rectifer will same ?
My question is this.
W,salam. After conversion voltage will be increase but we can check only Exciter stator voltage with multimeter and main rotor voltage are different also we cannot check it.
Superb
Thanks sir
I have a request bai, please make video for how connection identify alternator terminal box (all sensor & Engine control connection from cat Generator).
❤❤❤

2 hours bad Voltage Variation hota hei AVR 449 and 731 Hei kya problem ho sakta hei
I have a one query...about voltage control and load control.
Actually when we need to increases or decrease voltage/load set.. avr only feed excitation current to exciter where as rom almost fixed. But i want to ask u what happen when excitation current feed to exciter from avr to fulfill our setpoint (either volt increases/Decrease Or load increases/decrease) ...confusion is here that field excitation is same but why volt increases or load current increases..
Excitation field is not fixed, its always vary on load
@@AsadElectrical may be I can not explain quesrion perfectly ..
Suppose: rpm 500, load 18mw, volt 11kv, current 1200 A, excitation current 10A, excitation volt 105 volt, pf 0.8,
If we change pf 0.8 to 0.85,
Gen volt, load is being same, rpm same, just output current getting low Slightly.
My question is actually it's control by excitation feed by avr. But excitation feed is send to aux exciter, then it creat 3 phase power to diode bridge, then pure DC actual feed to main rotor field ..which is totally not physically connected with any control.
How this actual rotor field control for pf 0.85 and actually what is going on this situation.
Any body can explain??
Physical connection is not necessary because magnetic fields also work to reduce or increase amps.
Very nice explain and informative video's, But couldn't understand residual voltages available in stators
th-cam.com/video/nCvgO4-K3Js/w-d-xo.html
@@AsadElectrical THANK YOU MY GOOD TEACHER ..ALLAH HELP US..my NAME MUHAMMAD NAWAZ..
And also explain why first we convert from AC to DC then again From DC to AC and finally convert AC to DC.
Because we need DC supply to make constant magnetic field around the rotor.
Sir please one video on PMG
th-cam.com/video/yXRJVzZgR-A/w-d-xo.html
New video coming soon also
Sir excitor me chumbak q lagate hai plz bataiye
Asad bhai dvr ko bhi breif kre and AVR aur DVR mein difference bhi btae
th-cam.com/video/ymxpGTpsT2E/w-d-xo.html
PMG using for what purpose you saying in your video for sensing are you sure about it, and also what is dynamic excitation you know about this system.
PMG makes regulation more reliable and stable instead of self excitation.
th-cam.com/video/yXRJVzZgR-A/w-d-xo.html
Sir can you add English subtitle. It would be a big help for us who didn’t understand other language. Thank you
I already added on this video
👌💐👌💐
Sir written notes mil sakte hai kya pls?
Assalamualaikum
Sir singal fase me avr lagane ke liye diwod konse nikalna he please bataye connection samajh me aagaye par diwod kese niklenge
Asad bhai AVR duty cycle kia hota ha genset k display pe?
kia kam hota ha iska?
Duty cycle ratio ya percentage ko kehtay hen. kisi bhi equipment k kaam karne ka ratio
If we have a PMG do we need residual voltage for initial magnetic field
Yes, but PMG helps if residual magnet get lost
Sir till now not explained the generator rotor earthfault protection system with diagram
Ok i will try
Same procdure in brushless excitor system ?
If we don't get y phase of residual voltage during synchronised generator in power plant then what is the main cause ?
Yes it is brushless system.
If any phase missing, you need to check windings/connections
AC input Acoutput AVR ho sakta hai
Dc current kese rotating field bna sakta hai?
Jab ham rotor ko rotate krengy to wo field bhi rotate hogi
What is residual voltage? How its produced? Plz mention link of ur video thanks
th-cam.com/video/nCvgO4-K3Js/w-d-xo.html
How much ohms does the exciter coil is thanks bro keep it up
Exciter field is about 4 ohms and exciter rotor is less than 1 ohms
Thanks that is for big generator like 10 k and up
hello dear, please may you add subtitles for the video because it's really difficult to understand your ideas.
Thank you and all my respect
i have the same problem too
😍😍😍😍
Main rotor Input supply DC or ac
DC
Avr se kitten volts DC generate hote hai
Different hotay hen
If PMG excitation produces 60 to 70 voltage then what will be the mains excitation voltage.
Main Excitation voltage remain same, PMG only helps AVR
Assalamualicum Sir. Could you please inform that how much sensing voltage come in AVR for 11 kv alternator??
Its depend on AVR. 11 kv step down to 110, 220 or 380 from PTs than come to the AVR
Walykum assalam
@@AsadElectrical Sir Thank you so much. Kindly make video about this very soon 🙏🙏
Bhaiya single ya three phase janeretor mai kis janeretor mai kaun sa avr lagega kaise ptaa karey
Ya phir kitne volt ka avr lagegaa kaise ptaa karey
As per manufacturer requirement
@@AsadElectrical bhaiya kisi bhi janeretor k liye avr select karne k perametar kya hai
@@DevendraSingh-pt1qr generator rated voltage aur excitation current and voltage range k hisab se koi bhi AVR use kr sakty hen.
@@AsadElectrical bhaiya kitna excitaion volt aur reted current hone per kitne volt ka avr lagegaa
@@DevendraSingh-pt1qr Generator nameplate pe uska maximum excitation current aur volt mention hota he uskay hisab se. Warna max 10 amps ka use krsaktay hen aur excitation volt 40 tak hona chahye agar 400 v ka generator he
Kya krna chahiye. Senci ka ganretr

Avr take in put from pmg ....how many voltage pls...?
th-cam.com/video/i4QCNs8bncQ/w-d-xo.html
60/70 volts three phase
How to check efficiency of DG set
Sir our gen pmg op voltage is 240v ac 275hz 3phase.. So why output frequency is so high??
PMG frequency is always high because of many poles in exciter and this is need because of smooth operation
Sir but how it becomes smooth by increasing no of poles and that in turns increses frequency
If generator is off than from where the excitor will get the initial field supply ?
