Transformers

Some specific types of transformers:

Transmission and Distribution Transformers

If the core of the transformer is constructed from a stack of identical laminations, a MAGNETO (2D/RS) analysis may be sufficient though complicated geometries may require AMPERES .

Often, analysis of the electric fields in and around the transformer is even more critical than the magnetic analysis. Usually this requires COULOMB , though simple geometries may permit the use of ELECTRO (2D/RS).

Instrument Transformers

In addition to magnetic analysis, analysis of the electric fields in and around the transformer may be critical to the safe operation of the device. Usually this requires COULOMB , though simple geometries may permit the use of ELECTRO (2D/RS).

Power Supply Transformers in Electronic Devices

Normally MAGNETO (2D/RS) would be sufficient, though transformers with air gaps might require AMPERES for design analysis.

High voltage transformers may require analysis of the electric fields in and around the device to determine safe operating conditions. Usually this requires COULOMB , though simple geometries may permit the use of ELECTRO (2D/RS).

LVDT

Usually OERSTED (2D/RS) or FARADAY (3D simulation) will be required because of eddy currents induced in the sensor components. If the sensor is composed of ferrite and/or laminated materials, MAGNETO (2D/RS) or AMPERES (3D simulation) should be sufficient.

Simulations using INTEGRATED software permit determination of transformer performance as well as equivalent circuit parameters.
