Fire Suppression (Water Mist) Metalclad M/V Switchgear
Fire Suppression (Water Mist) Metalclad M/V Switchgear
(OP)
Can anyone provide me with information on water mist fire suppression systems. I have previously read an article where water mist jets were installed in the air insulated bus chamber of 11kV S/G for extinguishing fire. I would appreciate any information on this type of system.

Sounds bogus to me!

I have seen smoke detectors installed directly above, but not water sprinklers.
Of course oil dilled equipment is another issue.

Aside — AFFF has been used in large pulsed-power research facilities, but I've not witnessed related post-discharge mopup.

And consider the potential of a leak in the misting system while the power was on! I will not entertain the arguments that "it won't leak". That is just a challenge to good 'ole Murphy.

jraef, that is a good point. I'll bet the ‘3-6% additive' does not hasten evaporation, much less decrease conductivity of the medium. Seems kneejerk reaction to Halon [via the Montreal Protcol] tended to promote hasty {but surely politically correct} support of "new and improved."
