Thank you so much sir, i cleared my doubt after watching this video.....

Sir What is relay used in vaccum circuit breaker

@ashishverma6713 3 года назад

Thankyou very much sir finally I got chopping ❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤

@vysyarajunagasriraju5454 3 года назад

sir it is why only occur in air break CB why not occur in other CB's

@veena3889 3 года назад

Nice explanation Thankyou sir

@surendrakverma555 2 года назад

Very good. Thanks 🙏🙏🙏🙏🙏🙏

Excellent, make video on single pole circuit breaker and compare same with gang operated. Sameway phase shift transformer and vector surge relay too

In current choping why high voltage across circuit breaker cause ionization where as in method of arc extinction we have studied that high arc voltage causes extinguish the arc since arc voltage is greater than system voltage.

@ramitmahendra 4 года назад

@@lecturesinelectricaleng thank you sir for your prompt reply :) Sir, I am still confused. Arc voltage greater than system voltage causes ionisation or deionization.

Great content!

Thanks Sir

@sudhakaravv9444 3 года назад

Why arc votage is in rectangualr shape sir? Any particular reason?

@parthshaha7663 7 месяцев назад

Not specific reason, but ig due to plasma state of arc

Nice explanation

Sir, if current chopping is having huge sudden change and we have to use a shunt resistor to damp the oscillations why are we using it ? because we can anyhow damp the oscillations just by using a shunt resistor even without current chopping

thank you sir...

@nikhill.ambule7447 3 года назад

Sir you are great. Thankyou ❤️

@vamsivakalapudi3391 3 года назад

sir, at 10:45 sec, you said "When using resistance switching, change is only 2.5 Amp and when not using it, it is 5 Amp", How sir ?

@sasidher8922 4 года назад

sir,again after some time, how medium is deionized in circuit breaker during high voltages?

@himanshu2232 4 года назад

Thank u sir

@S.j-ze3nz 3 года назад

Thx sir 🙏🙏 Google metting attemp kase kre sir

@sasidher8922 4 года назад

sir, in vaccum CB and SF6 CB , how to overcome current chopping?

@kwakubiney5175 3 года назад

@@lecturesinelectricaleng Not entirely true. Can happen in vacuum CB as well.

@pikuroy3084 3 года назад

Sir why the TRV is superimposed on the system voltage in the negative direction unlike in the previous topics where the TRV is appearing in +ve direction when the system voltage is in +ve half cycle?
