Bunding Oil Filled Transformers To Bund or Not to Bund andorra transformer tank fire volume

Apr 25, 2019Matthew Pilgrim Senior Consultant Engineer (FM Global). Carl, in general transformer bunding is a good idea, but can be a costly exercise for existing installations. Factors to consider are the cost and lead time of the transformer, its impact on production, whether an oil fire would expose adjacent transformers or buildings and the type of oil used (mineral oil, natural or synthetic esters).Code Requirements on Aboveground Storage Tanks Uniform Fire Code, 2000 Edition Protected Tank.

When an internal fault occurs in an oil-filled transformer not protected by the TRANSFORMER PROTECTOR (TP), the electric arc produces a large amount of explosive gases. Those gases quickly create an overpressure that leads to transformer tank explosion. The tank cover is often damaged, opened, and the explosive gases being in contact with air (oxygen) causes a fire.Conservator ShutterWhen an internal fault occurs in an oil-filled transformer not protected by the TRANSFORMER PROTECTOR (TP), the electric arc produces a large amount of explosive gases. Those gases quickly create an overpressure that leads to transformer tank explosion. The tank cover is often damaged, opened, and the explosive gases being in contact with air (oxygen) causes a fire.Despite 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. Traditional mitigation methods use, for
