Sažetak

Liquid-filled power transformers typically contain thousands of liters of flammable insulation. When this insulation breaks down, there is a high risk of transformer failure that would endanger human life, generate environmental hazards, and destroy valuable assets. Because live tests involving arcing are expensive and potentially dangerous, numerical simulations are a useful alternative to study faults over a wide range of transformers. Since bushings are common sources of transformer failure, we examine the role of deploying a transformer fast depressurization system on two simulated transformer designs, with protections localized in the bushing turret region, to ensure that the transformer is robust to internal arcs.
