fleet of 765kV transformers over a 20-year period [1]; only 0.14 percent of these involved fires. gEORgE FRiMPOng, STEPHAnE PAgE, kJELL CARRAnDER, DOn CHERRY Every year, a number of transformer failures result in a fire. Because the transformers insulat-ing fluid is flammable, fires can be sustained for several hours or days. The fire,Transformer Foundation - Oil Containment Area Sizing uzbekistan transformer tank fire volumeMar 24, 2011I am working on a design of a transformer foundation. Transformer contains 1050Gal of oil. That is quite a bit of oil, that would require 146 cu. ft. of containment volume around the transformer pedestal, if I add crushed stone into the pit, it will quadruple the volume. I have an option of building an underground containment tank with a sump pump.Transformer Foundation - Oil Containment Area Sizing uzbekistan transformer tank fire volumeThere are a few variables with cooling fins for Air Natural convection cooled transformers. The ratio of weight of oil to kVA rating follows a power series. I digitized one design for an example into a spreadsheet. I estimate 9 kg/kVA at 300kVA or uzbekistan transformer tank fire volume

volume 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, forFire Protection in Substation Transformers T&D WorldWhere 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.

These values show the varying degrees of separation needed between a transformer and an adjacent building. The distances increase depending on the fire hazard introduced by the volume of liquid in the transformer and the liquid type.
