Cable Tutorial Series
In this set of eight tutorial models and associated documentation, you can investigate the resistive, capacitive, inductive, and thermal properties of a standard three-core lead-sheathed XLPE HVAC submarine cable with twisted magnetic armor (500 mm2, 220 kV). The series includes a 2D, 2D ... Читать дальше

Permanent Magnet
As an example of a magnetostatic problem, consider how to model a horseshoe-shaped permanent magnet. One way is to treat the entire magnet as a ferromagnetic material, where the two end sections are defined as being pre-magnetized in different and opposite directions. Читать дальше
Magnetic Field of a Helmholtz Coil
A Helmholtz coil is a parallel pair of identical circular coils spaced one radius apart and wound so that the current flows through both coils in the same direction. This winding results in a uniform magnetic field between the coils with the primary component parallel to the axes of the ... Читать дальше
Heating Circuit
Small heating circuits find use in many applications. For example, in manufacturing processes, they heat up reactive fluids. The device in this tutorial example consists of an electrically resistive layer deposited on a glass plate. The layer results in Joule heating when a voltage is ... Читать дальше
Computing Capacitance
A capacitor, in its simplest form, is a two terminal electrical device that stores electric energy when a voltage difference is applied across the terminals. The stored electric energy is proportional to the applied voltage squared and is quantified by the capacitance of the device. This ... Читать дальше
High Voltage Insulator
This example demonstrates how to use the Electrostatic interface to calculate the surface electric field of a typical high-voltage insulator. It is shown that the inhomogeneity and the maximum of the surface electric field are greatly reduced with the installation of the grading rings. ... Читать дальше
Permanent Magnet Motor in 3D
Permanent magnet (PM) motors are used in many high-end applications, such as in electric and hybrid vehicles. An important design limitation is that the magnets are sensitive to high temperatures, which can occur through heat losses caused by currents, particularly eddy currents. In ... Читать дальше
Computation of losses in a three-phase power transformer
Electromagnetic analysis of a 400kVA, 15kV/400V three-phase power transformer with Y-d connection and multiple primary and secondary coils with hundreds of turns. The model features the standard open- and short-circuit test in 2Daxi and 3D simulations to estimate electrical quantities ... Читать дальше
Inductive Heating of a Copper Cylinder
The induced currents in a copper cylinder produce heat that in turn change the electrical conductivity. This means that the field propagation has to be solved simultaneously with the heat transfer through the cylinder and surrounding system. This model shows this coupling between eddy ... Читать дальше
