Transformer Protection
Transformer Protection
(OP)
Hi,
I would like to know is there any specific section in NFPA 15 or 850 or IBC that specifically says that all transformers shall be protected by water spray system for outdoor or indoor installation and where transformer has oil capacity 500 U.S gallor less or more. I know NFPA 15 mentions water spray but it does not mentions whether it is required or not and if required (is it for big transformers or small in terms of their oil capacity).
Thank you for help.

I have very limited experience with Canadian construction codes so good look in your analysis.

Make sure you have the sound on so you can hear the explosion. The liquid you see coming out before the explosion is oil.

Insurance inspectors give a lot of importance on oil spill containment (check IEEE980) and fire walls in general.
The risk of fire/explosion is related to the inspection and maintenance of the transformer. In my country Costa Rica the inspection and maintenance is very good since there is a big very good lab that do most of the maintenance of mostly all of the transformers here, and mostly all use the same naphtenic modern oil, even it is not a fire safe oil, it is very safe from the operation point of view, we have never had a big transformer fire. Only small incidents you can count with the hand in the last 60 years.
I work for an electric facility and in general we use spray protection, due to the amount of oil stored where the transformer is critical for business, where fire walls or containment installations of existing facilities does not go with the code.
