To accurately compute the pressure wave propagation inside a transformer tank, the MTH model is based on:

• A theoretical description of the gas and the liquid oil as compressible media
  

• A robust and accurate numerical tool to solve the complex physical model equations on complex transformer geometries
  

    Various configurations can thus be defined and numerically tested. Various physical effects can be accounted for.

    This numerical tool also enables the accurate computation of the pressure wave (dynamic pressure) interaction with the tank 
    structure.
