WEBVTT - High voltage simulations with QuickField

00:00.000 --> 00:20.000
Hello and welcome to our webinar. Today we will speak about high voltage modelling with QuickField FEA software. My name is Vladimir, I will make a short introduction and then my colleague Alex will continue with live presentations of various simulation problems related to high voltage equipment.

00:21.000 --> 00:44.000
High voltage is formally a term used in electrical engineering for systems carrying more than 1000 V between conductors, or 600 V between conductors and ground. But in fact, all systems which may have a risk of electrical arcing between the electrodes or electrical breakdown through the insulation may be considered as high-voltage.

00:44.000 --> 01:04.000
And QuickField provides plenty of features useful in the high voltage electrical engineering. Analysis formulations required for such simulations are from the Electric suite family – it may be Electrostatics, AC Conduction or Transient Electric analysis.

01:05.000 --> 01:22.000
Here you see a list of all analysis options available today. They include AC, DC and Transient magnetics, Electrostatics, AC and DC conduction, Transient Electric analysis, Transient and Steady State heat transfer and mechanical stress analysis.

01:22.000 --> 01:51.000
They are bundled into three suits for Magnetic analysis, Electric analysis and THermostructural analysis. All types of analysis are available for 2D, and for 3D we now have Steady State Heat transfer, DC conduction and Electrostatics. And as I mentioned – for high-voltage simulations Electrostatics, or AC Electric modules are most often used.

01:51.000 --> 02:18.000
2D modules may be used separately or in some combinations, to perform the coupled analysis with Multiphysics coupling. This slide shows possible types of combined analysis – bringing the electromagnetic losses as heat sources for thermal analysis, importing the thermal loads to stress analysis, using the electromagnetic forces in the mechanical stress analysis. 

02:28.000 --> 02:52.000
QuickField workflow is extremely simple. You need to specify the model geometry and build the Finite Element mesh in the Model Editor (from scratch, or starting from CAD geometry file import), define the physical properties and field sources in the Data Editor, and after running the automatic solving procedure – analyze the results using powerful interactive graphical postprocessors.

02:53.000 --> 03:27.000
Geometry of QuickField models may be chosen from the following classes- 2D plane-parallel or axisymmetrical, which is presented by an upper half of the axial cross-section, and for those types of analysis which are possible in 3D – geometry may be defined using the 3D extrusion from the planar sketch, or imported from the STEP file with 3D geometry created in CAD.

03:29.000 --> 03:47.000
Unique feature of QuickField is the existence of the full-features open object Application Programming interface, which allows interaction with QuickField FEA core for other applications, created in many programming environments.

03:47.000 --> 04:02.000
This allow using QuickField model as a part of a larger simulation or control system, for automation of the repetitive tasks, optimization and anything where the manual interaction with the FEA model is not sufficient.

04:03.000 --> 04:30.000
Unique feature of QuickField, which makes it the tool of choice of many researchers and engineers around the world – its simplicity. We are proud to say that QuickField does not need any dedicated training. Now my colleague Alex will demonstrate it showing you the live simulations of various high-voltage problems. Alex – please continue.
