Transformers & Power Engineering Simulation Software

High voltage and high power devices and equipment  are the backbone of modern power transmission networks and systems.  Such devices and equipment include switchgears, transformers, bushings, busbars, high voltage insulators, cables, corona rings, and power chokes.  Their design is a daunting task for the power engineer due to the challenges and physical limitations that they pose, including:

  • Insulator or dielectric breakdown which result in corona and sparking.
  • Eddy current and core losses which lead to overheating and deformation.
  • Skin and proximity effects which may cause cross talk and distortion and the melting of conductors.
  • Electrostatic discharge which damages electronic devices and circuits.
  • The expected long life of components in the electrical grids such as transformers.
  • Transient phenomena such as eddy current resulting from lightning strikes.

Accurate computation of electric and magnetic fields

All electric power phenomena such as transmission, dissipation, loss, and reflection  are Maxwellian in nature and hinge on the knowledge and understanding of the electric and magnetic fields.  All other auxiliary quantities such dielectric breakdown, eddy current, eddy loss, core loss, magnetic force, electric force, power loss,  impedance, and inductance are derived from the main field quantities.   Hence, the accurate computation of the fields is the clue to all of the above challenges and limitations that the power engineer faces.  EMS with its seamless integration in  SOLIDWORKS®, Autodesk® Inventor®, and Ansys SpaceClaim and multi-physics capabilities, is an accurate, powerful, and a must-have electric and magnetic fields simulator.  Below is a list of power engineering examples that testify to the power and accuracy of EMS.
