The Depressurization StrategyThe Experimental CampaignsExperiments and Results AnalysisNumerical SimulationsLarge Transformer Explosion PreventionMitigating the effects of a transformer explosion consists of either limiting the explosion consequences by extinguishing the subsequent fire,usually with fire walls or sprinklers,or preventing tank explosion by using mechanical technologies that absorb the high overpressures generated by the electrical arc,thus preventing the tank rupture and the subsequent fire.Indeed,the electrical fault generates a dynamic pressure peak,which travels at the speed of the sound inside the transformer oil,1,200 meters per secSee more on power-engThe Masterpiece Aquarium of David Saxby Reef Builders Sep 30,2016·Unlike most large tanks where the technology is housed in the basement or adjacent garage,for this tank David placed the filtration and all related technology in a 200-year old cellar approximately 40 meters away.Both the tank and the filter room are sited at the same level.Therefore gravity cannot be used to return water to or from the tank.PADMOUNT EQUIPMENT LOCATIONS / CLEARANCESVOLUME 17 ENGINEERING CONSTRUCTION STANDARD PE0010U PADMOUNTED EQUIPMENT LOCATIONS Where NVE desires to install transformers and padmount equipment on customer's premises,the customer shall furnish a satisfactory right-of-way for such purposes,and shall provide adequate space for the installation. and to meet fire safety PADMOUNT EQUIPMENT LOCATIONS / CLEARANCESmasonry fire barrier wall 3' from the back or s ide of the equipment to the side of the combustible wall (see figures below).Barriers must be at least 9' wide and 15' tall.If there is a combustible overhang on the building,that overhang must be 16' or greater from the bottom of the transformer (10' radial clearance from a 6' high transformer).
