insulating medium. This volume entitled, Facilities Instructions, Standards, and Techniques (FIST), Volume 3-32, Transformer Fire Protection, includes a discussion of this alternative. 2. Scope This volume outlines basic considerations and requirements for fire protection of large, mineral-oil-filled, GSU transformers at Reclamation powerplants.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.Guide for Transformer Fire Safety Practicesfor good Transformer Fire Safety Practices that would help transformer designers and users to define and apply best practices in the domain of transformer fire. The working group WG A2.33 has endeavoured to do this by preparing this Technical Brochure which covers the following aspects of transformer fire safety:

Fire protection for indoor transformersDespite 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

Fire detection for oil filled transformers - NFPA (fire , slovenia transformer tank fire volume

I am not sure about the reason for a heat/ smoke detector to cover an oil filled transformer. The oil is normally a non combustible (under definition of NFPA) product and transformers under many circumstances blow up at which point smoke detectors would be meaningless. I have never seen a transformer fire but I have seen them blow up.Fixed water spray systems for fire protection (NFPA 15 , slovenia transformer tank fire volumeThe volume which can be controlled by a single system actuation (control) valve can not exceed 500 gal (1893 liters). , slovenia transformer tank fire volume Every water spray system shall have at least one automatic water supply, being either a gravity tank (please refer to NFPA 22), a fire pump with adequate supply (please refer to NFPA 20) or a pressurized tank (please refer , slovenia transformer tank fire volumeTransformer - WikipediaTransformer oil is a highly refined mineral oil that cools the windings and insulation by circulating within the transformer tank.
