Scope This volume outlines basic considerations and requirements for fire protection of large, mineral-oil-filled, GSU transformers at Reclamation powerplants.Second Revision No. 18-NFPA 59A-2015 [ Section No. 2.4 ]A fire over the whole surface of the liquid contained in the tank, assuming the roof is completely lost (2) The analyses shall account for the following: (a) The duration of the fire, the radiant heat emission characteristics of the fire, and the physical attributes of the fire Transformer tank rupture mitigationsystems. Slow clearing of the internal fault can lead to tank rupture, and potentially spilling tens of thousands of gallons of oil causing fire, and a horrendous environmental cleanup. If this happens, many power companies generally prefer to replace the faulty transformer, rather than attempt to fix the tank with an unpredictable result.

Where a firewall is provided between transformers, it should extend at least 1 ft (0.31 m) above the top of the transformer casing and oil conservator tank and at least 2 ft (0.61 m) beyond the width of the transformer and cooling radiators or to the edge of the containment area, whichever is greater. Power transformer fire protection systemsDespite design precautionsvolume of gas builds up, the pressure inside the tank increases significantly. As the metal tank starts to expand, it will deform and may even rupture. The consequences of such an explosion can include oil spills and even extensive fire damage to both the transformer and surrounding equipment.

Transformer - Wikipedia

Transformer oil is a highly refined mineral oil that cools the windings and insulation by circulating within the transformer tank. The mineral oil and paper insulation system has been extensively studied and used for more than 100 years. It is estimated that 50% of power transformers will survive 50 years of use, that the average age of failure , togo transformer tank fire volumeThe Purpose Of Transformer Gas RelayThe transformer gas relay is a protective device installed on the top of oil-filled transformers.
