Fire Protection systems for transformers
(OP)
Power Transformers are provided with various types of fire protection systems like deluge (water sprinkler), water mist with high pressure water, nitrogen injection system, water curtain etc. The water mist system came in to use during last 20 years. What is the service experience of it? Any where this is extensively used? Whether the nitrogen injection system(originally by French) is widely used in US &UK? Any account of success rate?

Similar, albeit smaller, systems are commonly in use in older British substations where the switchgear is legacy oil-filled equipment. The CO2 suppression is provided in case of a fire in the switch house. The system is manually disabled before entry into the protected zone. I haven't see anything similar used to protect against an oil-filled transformer fire, but most of our transformer are located outdoors where the gas flood would quickly disperse. Vault-type installations are unusual.

These transformers were in hewed out-of-rock rooms buried deep in the rock structure. As I was marveling at how they even got them into place a guy told me they were the only power plant transformers that were inside a dam in the USA. I'm not sure if it was true but it was definitely not something I'd seen before.
