Sir..yours all the vedio is very important for eng.and also electrician .ur teaching style is a great.i had many doubts clear from the help of this vedio .but I have a request.sir..pls vedio will make in the discription .some equation and drawing also includes in the vedio.after all thank u so much for improving our ideas . continue with us ..sir
Sir we are providing protective devices in CB so now my question is why we can start the motor in fault condition .... How the breaker will give permission to start the motor in fault case
hii. Thank you for posting very informative video. Just got one doubt, when the contacts of a breaker is same for making & breaking then how can it fulfills the requirements of different ratings(making & breaking)?
As he explained making current is 2.55 times of breaking current , and the breaking current have direct relation with voltage , if voltage increases current will reduce
Sir if the contacts can bear a breaking current of 40KA(say),then how can they bear a making current of nearly 102 KA.I mean to say when the contacts can't bear current of more than 40KA,how can they bear current of 102KA. Also please explain why is there a rise in the current at the time of making?
And one more dout is breaking means we isolate the motor in supply so this off condition y we need higher current there coil supply only going to cut off ....I cant able to understand this
Sir Maine abhi check Kiya ,ek HT breaker hai uske rating hai 800A ,aor braking current hai 25/3sec ,aor LT breaker hai 3200A breaking current 60ka/1sec ,doosra hai 1600A beaking current 50KA/1sec,aor 800A ka braking current hai 50Ka/1sec ,laykin sir enme making current nhi diya hua hai ,agar mai aapke btye formulla say nekaalu to Jo current value aayega wo making current hoga per time bhi wahi rhega jyese 50ka*2.55=63.75/3sec timing ka doubt hai
@@electricalwithabhishekjoshi tthank you sir for reply but sir hamare yaanh L&T ke breaker hai,Maine aapka video dekhene ke baad preker me check Kiya to usme Sirf breaking current hi likha hua tha

Please make video on acb
Sir i think making current ki safety 1 second hoti hai aur breaking ki instant or milli seconds...??
That's good explanation.

how to find making and breaking current capacity of CB. Is it mentioned on nameplate or do we have to perform certain test.
Mention on name plate
Hii sir kindly share videos on ZSI in breakers and Discripution in breakers
per jab breaking capacity per CB damage ho jayega to replace karengey na use ,doosri baar kyu ON karengey
Sirjii...
Both breaking current and Short Circuit current rating are same. Right..?
Sir,
Please explain what is Operating Duty of VCB?
O-0.3 sec -co- 3min -co
Difficult to explain it in message.
Good
Sir, what is different between 33kv /415and 6.6kv/415v,pl explain.in trafo.
Very nice sir
Can we said that Making current and inrush current same
Why the current will be more at the time of making the contact in CB?
The ways to reduce this current to be explained.
Give details of 3 phase welding set connection to rccb

Sir, which coil has more resistant, making coil or breaking coil?
Subham it's more or less same..
Because both closing and tripping coil is important.
sir what is a bus raiser and how it different from bus coupler.
Vikash, ispe ek video bana denge.
Sir
Ct calculation in the relay settings
Kedar, watch my video on CT operated relay setting. Aapko Sab information mil jaegi.
Making current is peak value or RMS value?
Making current is a peak value of Circuit Breaker
Breaking current is the RMS value of Circuit Breaker.

Great job sir👌👌
Thank you Dhruv...

What is the reason, oftenly making current of 33kv breakers are less than that of 11KV breakers?
As he explained making current is 2.55 times of breaking current , and the breaking current have direct relation with voltage , if voltage increases current will reduce
Sir how I know what is the making current and braking currentof a vcb..
Is it mention at vcb name plate
Keep it up bro
Thanks Ali Mehboob..
Sir if the contacts can bear a breaking current of 40KA(say),then how can they bear a making current of nearly 102 KA.I mean to say when the contacts can't bear current of more than 40KA,how can they bear current of 102KA.
Also please explain why is there a rise in the current at the time of making?
Gud question my dout is also same
And one more dout is breaking means we isolate the motor in supply so this off condition y we need higher current there coil supply only going to cut off ....I cant able to understand this
I think making current trip is for 1 second
And breaking trip for instant fault in any system.
Thk
Good explain
Thank you Surendra...
Sir how direct testing of circuit breaker is done?
Can you please tell me the equation to find out the Breaking Current?
short ckt breaking current = 44 kA rms
what is meant by this,
I found it on a VCB nameplate
Nice video, Great
Thank you Praful 🙏

Suryakant Breaker pe breaking current ki timing likhi jati hai.

Ha sir braking ka timing likh hai mai ye punch rha tha ki making current ka timing aor current dono nhi likha hai
Yes dear. Jaise motor pe sirf output Power likha rehta hai. Input power nahi rehta.
Waise hi Breaker mein breaking current likhte hai.

How to do setting of ACB
भाई मेने सुना है vfd से कुछ होर्मोन निकलते है
ये क्या होते है और इसका किसी मोटर या पैनल बोर्ड पर क्या प्रभाव पड़ता है
Please reply me bhai🙏
I think aap harmonics ke bare mein bol rahe hai.
Harmonics ka simple meaning hai disturbance. Harmonics se panel ne losses badh jate hai.
Harmonics se hear produce hoti hai.
