Prevention of Oil-Filled Transformer Explosions

Otherwise,when the tank is not equipped with any protection system,and if it is subjected to a similar low impedance fault,the tank is still exposed to very dangerous pressure levels (up to 15 bars,217 psi) after 120 ms (Figure 5.b) without the tank protection,the static pressure stabilizes around 7.5 bars (109 psi) and the transformer PADMOUNT EQUIPMENT LOCATIONS / CLEARANCESbelow).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).All NVE equipment will be installed in areas only,and have unobstructed vertical access for the accessibleOil-Filled Transformer Explosions Power EngineeringNov 01,2008 chad transformer tank building volume#0183;Moreover,without the tank protection,the static pressure stabilizes around 6 bars abs (87 psi) and the transformer would violently explode,as transformer tanks are designed to withstand static
