FeedbackHow to Handle Transformer Fire Protection Emergencies

·As the vaporized oil has a larger volume than the original oil,a large pressure rise occurs inside the tank.Once the internal pressure exceeds the transformers tank or lid pressure rating,the transformer tank ruptures at a seam or the lid,allowing flammable oil to escape and possibly ignite. How big of a fire hazard is a transformer?How big of a fire hazard is a transformer?Arrangements which tend to minimize the fire hazard of the escaped fluid are preferred.The layout of an outdoor installation shall be such that burning of a transformer with a liquid volume of more than 1,000 litres will not cause a fire hazard to other transformers or objects,with the exception of those directly associated with the transformer.Fire Walls Fire Risk Hazards Electrical Equipment - BS EN 61936-1 2010 What causes a transformer tank to go over 50kV?What causes a transformer tank to go over 50kV?Phase to phase and earth faults are virtually impossible.Lightning takes out a lot of pole transformers causing them to explode oil over an area greater than any bund could catch.Again,the root cause is now well understood.A lightning induced flash over on the HV bushing causes the transformer tank to rise to more than 50kV.Bunding Oil Filled Transformers To Bund or Not to Bund

Why is oil in a transformer tank dangerous?Why is oil in a transformer tank dangerous?Power transformers are one of the most dangerous electrical equipments because of the large quantity of oil they contain which is in direct contact with high voltage elements.Under such circumstances,low impedance faults that result in arcing can appear in transformer tanks once the oil loses its dielectric properties.Prevention of Oil-Filled Transformer Explosions1ZSE 5492-115 en,Rev.6 On-load tap-changers,type
