Hi
NFPA 850 established fast depressurization system like a mechanical passive system designed to depressurize the transformer a few milliseconds after an occurrence of an electrical fault. Currently there are several systems to avoid transformers explodes like: Sergi, Sentry, CTR, Jiangsu among...
Hi, I need to know if the Electrical Hazards Laboratory or any facility of FM can test an explosion prevention system for a transformer. Specifically a destructive test in order to prove effectiveness of and passive mechanical system according to NFPA 850 recommendations. Thanks for your help...

According to my knowledge: maintenance cost and time of vertical turbine fire pump are significantly greater than using a centrifugal fire pump. so if money or terms is an important issue,the best choice is CP.
dont try, do it!
Thanks Guys for your comments, actually I'm checking some data sheets about blast preventing systems for oil-isulated outdoor power transformers, I dont have so much time working on Fire prevention in my job, but this forum has been very useful as long as I've been studing the NFPA standard...
Im designing a deluge system for a 230 kV transformer in a electrical power station, at the moment of calculate area of transformer NFPA 15 suggest the following: "The water shall be applied al a net rate not less than 0.25 gpm/ft2 of the proyected area of a rectangular prism envelope for the...
