Hello sir I want to make a 3-phase AC current regulator (0-10A) using an old stepless transformer. Thank you for guiding me on the principles. Thank you
By using stepless transformer, you want to regulate three phase whose maximum current is 10 amperes. Three phase has 415 volts from phase to phase. For this, you will have to buy a variable transformer. Variable transformers can be known by other names such as auto transformer, dimmer set, variac. It comes in different current ratings such as 2 amperes, 5 amperes, 8 amperes, 10, 12, 16 and more. It comes in three phase as well as single phase. You will have to take three variants of single phase. All three will have to be installed in a ratio. For example, all three variable transformers will have to be connected to the same software. You will use three phase and Newton in the input. When the three phase output is correct, that three phase can give voltage from 0 volts to 415 or even more than 415. For more information, I have already uploaded a video about variable transformers. You can go to the channel and watch it. Can I help you further? Thank you for watching. Have a nice day.
Video mein 68 ohm ki resistance ki jagah per 5 k ka potentiometer lagakar aap Mili empier set kar sakte hain Mili ampere set hoga vah voltmeter ki display ki maximum account maximum Mili empier hoga
Sir , in my atx smps i am getting 8.8v on 12v yellow channel while all other are showing okay what to do? Where is the fault and how to fix it? Where are you from? Can i sent it to you to fix it.
I understand your problem. You should repair the power supply with great patience. Sometimes the voltage in the output is not correct due to faulty feedback area in the PWM IC of the computer's power supply or due to weak capacitor or faulty diode. This happens due to excess load in the SMPS. Use the repaired power supply in the computer only when the voltage is correct or you can use a new power supply in the computer. Thank you. Have a nice day
You are right but when we give 10 amperes of current to the primary winding of the CT, it gives an output of about 8 to 9 volts in the secondary winding. If there is a loss of current in the output, you can set the current with the help of 200 ohm preset. This is the simplest method but there is no accuracy. For accuracy, you can make an AC to DC converter using an operational amplifier IC. I will definitely tell you about AC to DC converter in the next video. Thank you. Have a nice day.
@@totalcircuit yes sir but first never to check voltage on open circuit ct always put burden resistor or short circuit when you apply 10amp ac current sec side is approx 10 mA. Putting a resistor of 200ohm will give you approx 2v. If you wanna try ac to dc converter there are lots of ckt on the internet but most do common mistakes only good for demonstration purposes but not accurate. I was looking for 1 mA resolution can say I have achieve most of it . If you need any help feel free to contact me. Thank
AC voltmeter Ho chahe DC voltmeter Uska maximum Mili empier display ki maximum counting hoga for example 3.5 digit display counting hoga 1999 Aap ICL7107 analog to digital converter Laga kar AC ya DC 1999 counting maximum Mili ampere dekh sakte hain jyada jankari ke liye AC voltmeter aur DC voltmeter ke bare mein Maine video banaa Rakha hai channel mein jakar aap use video ko dekh sakte hain Thanks for watching have a nice day
भाई साहब नमस्कार जी। आपने विडियो तो अच्छा बनाया है। लेकिन जो Screen(डिस्प्ले)उपर काली पट्टी दिखाई जाती है ईसी वजह से मिटर के अंक दिखाई नहीं देते।.... धन्यवाद।
1 empier se niche ka current test karne ke liye shunt resistance ke man Ko badhana hoga iske liye volt empier bhi dusra Lena hoga Mili empier mein current test karne ke liye AC voltmeter ka video banaa Rakha hai please channel mein aap use video ko dekh sakte hain Thanks
Utna acurate nhi bata raha hai sir video me jo apne ac volt meter ko ac amp meter banaya, lekin dc wala ko jo apne ac amp meter banaya hai wo acurate aisa work kar raha hai.
AC voltmeter ko Empire meter banaya usmein ho sakta hai setting karne mein thodi si bhi preset ko Sahi set nahin hota hai vah jyada empier per accurate nahin dikhata
good
Bahut achcha knowledge ❤❤❤❤❤
Very nice video.. Very well demonstrated.. 👍👍
Good idea ❤❤❤
Very good sir g .bht achay.shukria
Very nice

@@totalcircuit Thank you for your response. Could you please help me draw the diagram by hand? Thanks for this support
You are awsome sir. Make videos on making smps also.
Thank you very much! I will put in a video of SMPS soon
Amplifier mein Bluetooth headphone ka circuit kaise lagate Hain left right aur ground please detail video please 🙏🙏🙏🙏🙏🙏
Ok wait
This possible make with DC measurement?
There is a different method to measure DC current, for which shunt resistance is used.
Sir aapne adjustable ac load use kiya he vo kese kaam karta he ?
Variable Transformer se
❤❤❤❤❤❤
इसी मीटर को MiliAmpere meter कैसे बनाये मुझे 12 mili Ampere कॉऊंटिंग के लीये चाहिये

Mili ampear meter 4-20ma
A good idea.
But I think it doesn't work because a bridge rectifier need atleast 1.5 v or above to oprate so lover current is not measured

Is DC voltmeter ko AC 220 voltmeter kaise banaen
Okay
Sir मुझे AC 0 volt to 2500 milivolt meter बनाना है पर youtub पर कोई व्हिडीओ नही मील रहा कैसे बनाये
AC voltmeter Ho chahe DC voltmeter
Uska maximum Mili empier display ki maximum counting hoga

Subtitle hai aap band kar sakte ho
0.5 amp ke niche nehi araha hai.1amp ke upar tik hai.
100watt ke niche koe bulb jalane par amp read nehi karega.
1 empier se niche ka current test karne ke liye shunt resistance ke man Ko badhana hoga iske liye volt empier bhi dusra Lena hoga Mili empier mein current test karne ke liye AC voltmeter ka video banaa Rakha hai please channel mein aap use video ko dekh sakte hain

Sir ji 47ohem hi not 68ohem
Yes 47 ohm laga do
Yes 47 ohm lag do
