SGP202 Arc Phenomena in Circuit Breakers

[@aryanzee3072]

Sir ,in this lecture
1. Is 1ohm resistance is medium resistance which is in between the contact ?
2. Contact area means ?
Pls sir reply

Thanks alot sir🙏....very helpful for me while preparing for competitive exams..

[@ellareddyk]

Sir...I watch your videos and learn, thanq so much sir

[@nileshamigoo3829]

When contacts are separated the contact area will be increased or decreased tell mee

[@JUNAIDIKRAM555]

How you are calculating voltage gradient kindly elaborate b/w 5 to 6 min you discussed this point

[@aniruddhmathur3535]

Sir Thank you so much for such a wonderful explanation

[@aparnajoshi7457]

sir, why arc voltage is maximum at current zero? U said the arc is purely resistive, so arc voltage and arc current( which is the fault current) are in phase .

[@aparnajoshi7457]

@@lecturesinelectricaleng sir, but why voltage is maximum at current zero point ?For inductors due to 90 degree lag , voltage is maximum at current zero point. but here arc is purely resistive right.

[@sabashaikh6119]

@@lecturesinelectricaleng How does arc voltage vary for different types of faults? is voltage maximum for current zero for all types of faults?

Thanku sir for your valuable lectures 🙏

Very nice lecture

[@chandrasekhar9424]

As contacts are seperated then how contact decreases.

[@prabhatlalkarn1880]

is 132kv or 33kv sufficient for field emission??

[@prabhatlalkarn1880]

isn't this high voltage sufficient to cause breakdown of air or oil??

[@prabhatlalkarn1880]

sir, why heat is produced as current passes through arc??

[@prabhatlalkarn1880]

But a well established arc has very less resistance, then how such a huge amount of heat is produced??

[@prabhatlalkarn1880]

can we say that the arc current is equal to fault current ??

Sir try to make video in sysmetrical or unsysmetrical

[@rohitbhat5714]

Sir please try to make the videos of sysmetrical or unsysmetrical faults because I have lots of problem occuring during understanding the concept .

Sir I have sent u email of Murray loop test questions problem please try to solve it
