Magnetohydrodynamic modelling of high-energy power-frequency arcs in transformer oil: Energy partition and impedance-plasma-property relationships

Internal short-circuit faults in ultrahigh-voltage transformers can generate high-energy power-frequency arcs in transformer oil, creating substantial fire and explosion hazards. To investigate the coupled electrical, thermal, and fluid-dynamic behavior of these arcs and the influence of electrode geometry, a two-dim...
