Internal Arc pressure calculation

If you are meaning LV Air circuit breakers, there is a good paper from Schneider.

There are many papers from Dr Lindmayer which you can google and find.

May not give you exactly what you are looking for, but lots of excellent information about arc phenomena.

I am looking for data on arc pressure calculation inside LV Switchboard (Panels); not the arc quenching in ACB or MCCB.

Energy produced due to arc flash can be calculated based on fault current and time to clear the fault,similar to arc flash to study.

May be you can take the worst case of fault current and duration of arc and calculate the energy produced.

>50 people have seen this question. Only two answers. i was hoping to increase my own knowledge with some expert giving his/her view (sigh)

Well, rpsamel. have you got your answer yet?

If not....

The arc pressure in a good panel is due to the individual circuit breakers clearing short circuits .. (i am ignoring the output from contactors, switches etc here)... so, if you use good equipment, you don't need any pressure vent in the panel !

Yes? No?

i am provoking a discussion here, please respond in that spirit, thank you...

Dear sir

If you want further inputs can be given by calculating the actual energy produced by taking examples.But I thought we have given just tip from which the poster can pick up the thread further.

Quite correct. However, figures of arc energy are not usually published by CB manufacturers to the best of my knowledge, so i was curious as to how one can calculate this.

I haven't got any answers yet. But I am aware of an article written by F.Pigler in 'Energiewirtschftliche Tagesfragen', but unable to retreive it from the internet. It will be great if sombody can paste link to this article.

Perhaps the omission of an 'a' did not give you the correct result ? "Energiewirtshaftliche ..." Here is what i got : energie-online.de

But no luck with a sub-search for Pilger. Good luck searching.
