AVR

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.

@@AsadElectrical THANK YOU MY GOOD TEACHER ..ALLAH HELP US..my NAME MUHAMMAD NAWAZ..

I already added on this video

Because we need DC supply to make constant magnetic field around the rotor.

New video coming soon also

Ok i will try

PMG makes regulation more reliable and stable instead of self excitation. kzfaq.info/get/bejne/r76Cfbmrv822XXU.html

Yes, but PMG helps if residual magnet get lost

i have the same problem too

kzfaq.info/get/bejne/pKmmmrJlkrGXeqc.html

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

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.

Jab ham rotor ko rotate krengy to wo field bhi rotate hogi

Yes it is brushless system.

If any phase missing, you need to check windings/connections

Duty cycle ratio ya percentage ko kehtay hen. kisi bhi equipment k kaam karne ka ratio

DC

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 🙏🙏

Main Excitation voltage remain same, PMG only helps AVR

Different hotay hen

Ye output ko monitor karta he auto/manual modes par agar koi difference ho to signal deta he warna null rehta he

Theek Alhamdulillah

60/70 volts three phase

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

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

Hi. Your question is not clear

How much the throttle will open according to the load. want to know the use of woodward hand heald, thanks sir,
